Steel is an alloy of [[Material:Iron|iron]] and carbon (in the dimensions of 1%) and sometimes other [[metals]]. Depending on its exact composition, steel can have very different properties such as:
*Mechanical:
**Hardness: Resistance to indentation or abrasion, there are a lot of different scales and measuring procedures
**Strength:
***yield strength: maximal stress the steel can take before permanently deforming
***tensile strength: maximal stress the steel can take before rupturing
**Ductility: how much it can be plastically deformed before rupturing, good if you want to bend it in to shape but softer
*Physical:
**Electrical Conductivity
**Density: how much g/cm²
**Thermal Conductivity
**Thermal Resistance, melting and boiling point: BTW all of the above and below change depending on the temperature
*Chemical:
**Corrosion resistance: How strong it rusts

But not only the composition of the alloy but also the crystalline structure heavily influence the properties, just like coal and diamond (different structure and properties but both are carbon). The structure can be altered by the following processes:
*Heat treating
*Tempering
*Annealing

 
== Rebar ==

Rebar ('''re'''inforcing '''bar''') is a common steel product that is designed to reinforce [[concrete]] structures against tension.

As it is cheap and available in different diameters, it's suitable for many [[welding]] projects! You have certainly seen it on construction sites, although it probably looked more rusty than fresh from the store...

Stainless steel is worked with many similar tools as regular [[steel]], but there are differences!

Make sure to check whether you need special blades/bits/etc. for the machine you plan to use.

}}
Brass is an alloy of [[copper]] and [[Material:Zinc|zinc]]. As with [[steel]] or other alloys, its physical properties change with the proportions of the mixture.

It is easy to machine and "stronger" than [[aluminum]]. Due to its high copper content, it conducts heat and electricity quite well. The downside is the price which makes it unappealing for bigger parts.

Aluminum is a soft and lightweight [[metal]]. It is not magnetic and shows virtually no corrosion. Due to its low melting point it is often [[Aluminum Extrusions|extruded into pipes and profiles]].

== Shaping ==
=== Cutting ===
[[Hacksaw|Hacksaws]] (or a [[Pipe Cutter|pipe cutter]] if you're dealing with a pipe) can cut aluminum. Cutting sheet aluminum should also be possible with [[Fretsaw|fretsaws]] or our [[Scroll Saw|scroll saw]], but we haven't tested that yet.

Caution - abrasive discs as used with a [[Disc Grinder|disc grinder]] or [[Rotary Tool|rotary tool]] are reported to '''overheat and fail as the soft aluminum clogs them!'''

== Joining ==
Aluminum can be [https://m.youtube.com/watch?v=jtvOkI_pvMI brazed rather than welded].

MobiTobi: /* Electronic Prototyping */

== Welcome to my page :^) ==

I am now a not-so-new member of the comakingspace.
Below you will find a list of what I am working on and what I have created so far.
When I have made acceptable photos of my projects the write-ups will follow.

So far I have engaged primarily with the laser cutter, 3D printing and Autodesk Fusion.
Next I want to learn sewing 🪡 and improve my soldering.
In the long term I would like to work on expedient furniture, like collapsible desk designs and atlas compatible housing.

I have outlined help pages on creating [[ collapsible_designs | collapsible designs ]] based on reversible tenon and miter joins and on [[Advanced_laser_cutting_pipelines | advanced techniques ]] that made using the laser cutter easier for me.
It will take some time to write the text body. If you want to learn about any of the subheaders ''now'' shoot me a message on slack and I will get back to you.

Also trying to lobby for more morning opening times. Wish me luck 🍀

MobiTobi: /* Materials I have used */

== Welcome to my page :^) ==

I am now a not-so-new member of the comakingspace.
Below you will find a list of what I am working on and what I have created so far.
When I have made acceptable photos of my projects the write-ups will follow.

So far I have engaged primarily with the laser cutter, 3D printing and Autodesk Fusion.
Next I want to learn sewing 🪡 and improve my soldering.
In the long term I would like to work on expedient furniture, like collapsible desk designs and atlas compatible housing.

I have outlined help pages on creating [[ collapsible_designs | collapsible designs ]] based on reversible tenon and miter joins and on [[Advanced_laser_cutting_pipelines | advanced techniques ]] that made using the laser cutter easier for me.
It will take some time to write the text body. If you want to learn about any of the subheaders ''now'' shoot me a message on slack and I will get back to you.

Also trying to lobby for more morning opening times. Wish me luck 🍀

== Finished Projects ==

==== laser distance gauges ====

==== desk pen organiser ====

==== desk trading card shelf ====

==== speed token for mtg ====

==== fountain pen leather case ====

==== photography light box ====
(backdrop still missing)

== In the pipeline ==
In no particular order

* canvas roll-up cases
* Upcycle mint tins with custom linings
* Geometry teaching tools

Waiting Lists

2025-10-21T20:05:38Z

MobiTobi: /* Table Saw Introduction */

An overview of the waiting lists for our [[introductions]] that take more time than the [[tutors]] can usually invest spontaneously.

''If you want to "wait" for a vehicle spot, see [[Vehicle Workspaces|vehicle workspaces]].''

<big>'''How to Use'''</big> Please '''link''' your [[Special:MyPage|user page]] at the bottom of each list you're interested in after you've filled it with enough information to contact you and/or activated "Allow other users to email me" in your [[Special:Preferences|preferences]]!

DO: link yourself for the introductions you need for your project(s)

DO NOT: link yourself for all available introductions just because you might need it at some point in the future - chances are you'll forget something important by the time you actually use the machine!

If a list is full enough and/or you have been waiting for a while, please reach out to the tool's tutors and kindly ask for a date - maybe they've just been too busy, but it could also be that they missed the list filling up and would appreciate the reminder.

|similar=[[Belt Sander|belt sander]], [[Disc Sander|disc sander]]
}}
This machine stands in the [[Metal Workshop|metal workshop]] (next to the [[Bench Grinders|bench grinders]]) on a wooden box containing the manual and the accessories.

It is a combined disc and belt sander with a 203 mm sanding disc and a 914x100 mm belt sander. Both are always simultaneously driven by the 550W motor. Belt speed is 9,5 m/s and disc speed is 2850 rpm.

=== Features ===
The machine has the following features

* pivoting aluminium table for disc and belt sander (up to 45°)
* sanding belt unit tiltable from 0-90° (can be used horizontally and vertically)
* mitre fence for precise angle sanding
* suitable for longitudinal and front edges, round and mitre sanding and plane faces

In the factory version, the sanding disk was glued. We modified the machine to accept velcro-backed abrasive discs for much more comfort!

To change discs without disassembling half of the machine, you should slide a separator between the velcro pad and the sanding disc:

[[File:sanding disc removal.gif|thumb|remove it using the semicircular piece...]]
[[File:sanding disc replacement.gif|thumb|replace it using the circular piece!]]

=== Materials ===
As by the makers specification, the machine is permitted to process wood, and wood-like materials.

Use the disc sander for rough shaping, or to create outside curves on wood. Use the belt sander to sand your wood or other material. Should you use it to process other materials or light metals, such as Aluminium, adhere to the special precautions mentioned in the machine introduction, and make sure that the mounted sanding belt/ disk supports your material.

=== Proper Use ===
Always check the following before you start to work with the machine

* All cables and plugs
* Loose screws and connections. Damaged parts have to be replaced immediately, no operation of the machine in the meantime!
* Tight fit of table and safety fence
* The free and centered run of sanding belt and disc
* Attention! To prevent ﬁngers from being squeezed between the band and table, a maximum separation of 3 mm has to be maintained between the table and grinding band. Check that this is the case.

Configure the machine for your use case (table-angles etc).

* The angle stop can be used for angles of up to 45°, to the left or right, by releasing the locking button and adjusting the angle stop to the desired angle.
* The backing plate of the grinding belt has to be adjusted so it almost touches the grinding belt. In order to adjust it, release the two screws holding the plate in the machine rack. Tighten the screws again after you adjusted the plate.
* To remove the plate to perform special jobs (e.g. polishing or contour-grinding), loosen the two attachment screws

When working with the machine, do not apply too much pressure to the sanding abrasive.

As the machine offers no possibility to clamp your material, it is vital that the workpiece maintains stable contact with the worktable at all times!

This machine stands in the [[Metal Workshop|metal workshop]] (next to the [[Bench Grinders|bench grinders]]) on a wooden box containing the manual and the accessories.

It is a combined disc and belt sander with a 203 mm sanding disc and a 914x100 mm belt sander. Both are always simultaneously driven by the 550W motor. Belt speed is 9,5 m/s and disc speed is 2850 rpm.

=== Features ===
The machine has the following features

* pivoting aluminium table for disc and belt sander (up to 45°)
* sanding belt unit tiltable from 0-90° (can be used horizontally and vertically)
* mitre fence for precise angle sanding
* suitable for longitudinal and front edges, round and mitre sanding and plane faces

In the factory version, the sanding disk was glued. We modified the machine to accept velcro-backed abrasive discs for much more comfort!

To change discs without disassembling half of the machine, you should slide a separator between the velcro pad and the sanding disc:

[[File:sanding disc removal.gif|thumb|remove it using the semicircular piece...]]
[[File:sanding disc replacement.gif|thumb|replace it using the circular piece!]]

=== Materials ===
As by the makers specification, the machine is permitted to process wood, and wood-like materials.

Use the disc sander for rough shaping, or to create outside curves on wood. Use the belt sander to sand your wood or other material. Should you use it to process other materials or light metals, such as Aluminium, adhere to the special precautions mentioned in the machine introduction, and make sure that the mounted sanding belt/ disk supports your material.

=== Proper Use ===
Always check the following before you start to work with the machine

* All cables and plugs
* Loose screws and connections. Damaged parts have to be replaced immediately, no operation of the machine in the meantime!
* Tight fit of table and safety fence
* The free and centered run of sanding belt and disc
* Attention! To prevent ﬁngers from being squeezed between the band and table, a maximum separation of 3 mm has to be maintained between the table and grinding band. Check that this is the case.

Configure the machine for your use case (table-angles etc).

* The angle stop can be used for angles of up to 45°, to the left or right, by releasing the locking button and adjusting the angle stop to the desired angle.
* The backing plate of the grinding belt has to be adjusted so it almost touches the grinding belt. In order to adjust it, release the two screws holding the plate in the machine rack. Tighten the screws again after you adjusted the plate.
* To remove the plate to perform special jobs (e.g. polishing or contour-grinding), loosen the two attachment screws

When working with the machine, do not apply too much pressure to the sanding abrasive.

As the machine offers no possibility to clamp your material, it is vital that the workpiece maintains stable contact with the worktable at all times!

Disc Grinders

2025-10-14T15:07:45Z

MobiTobi: /* Discs */ added inner diameter needed from our angle grinder discs to the wiki. Essential information for beginners in the face of the number of different mounting systems.

We have a couple of disc grinders in the [[Metal Workshop|metal workshop]]. For small-scale applications, try using a [[Rotary Tool|rotary tool]] before you whip out this beast.

They can be used to cut or grind [[metal]] or [[stone]], depending on the disc used. [[Cut-Off Wheels|Cut-off wheels]] ''(Trennscheiben)'' should not be used for grinding and [[Grinding Discs|grinding discs]] ''(Schruppscheiben)'' should not be used for cutting as they are primarily reinforced for one of the purposes and could otherwise overheat and break.

== Safety ==
Due to the high amount of sparks generated, it is a good idea to wear a [[Face Shield|face shield]] as a second layer over your [[goggles]]! In addition, you should put on some [[gloves]] and [[Hearing Protection|hearing protection]] before using a disc grinder.

'''Make sure the disc is securely fastened and spins without an offset before cutting anything! The manual suggests letting it run for a minute without load, only if there is still no increased vibration after that it is safe to use.'''

Do NOT operate a grinder without its semi-circular collar - it will protect you from a lot of the sparks and shrapnel of the disc (if one breaks on you). Stay away from [[aluminum]] unless you bought special discs, it can reportedly clog and overheat regular metal grinding discs up to the point of explosion!

== Discs ==
Be prepared to bring your own [[Abrasive Discs|discs]] if you have specific needs! There are usually some leftovers of the basic types:

Laser Cutter Material Settings

2025-09-03T10:51:35Z

MobiTobi: add cotton fabric material settings

[[File:laser setting tests.jpg|thumb|right|200px|aftermath of a [[plywood]] testing session]]
Unfortunately you can't just calculate the perfect settings based on the '''power''' ("Watts") of a [[Laser Cutter|laser cutter]] because the actually delivered energy is always based on a combination of power and '''''speed''''', which is different for each brand or model of laser cutter. To make things more complicated, 100 % power in a cutting profile is not the same as 100 % power in an engraving profile... 

As there is always some trial and error involved, please share your experience with the others! You can often use experience from other machines as a ''rough'' starting point.

In general, cutting is usually done at 100 % power and the highest speed that will still result in a reliable cut. If 100 % speed still gets you through (e.g. paper or cardboard), you should reduce the power until you find the sweet spot. Besides the power setting, you can influence the invested energy by altering the pulse '''frequency''' - you may want to go lower on flammable materials like wood, where edges might otherwise become black, and higher on plastics like [[Acrylic Glass|acrylic glass]] where you are aiming for a "flame-polished" edge. [https://www.epiloglaser.com/assets/downloads/manuals/zing-manual-web.pdf page 46]

The width of the kerf ''(Schnittfuge)'' also depends on the laser settings and the material you're using and could be important for certain designs. [[User:Sebastian|Sebastian]] recommends to use the "DXF for Laser" [[Fusion 360]] export plugin [https://apps.autodesk.com/FUSION/en/Detail/Index?id=7634902334100976871] and testing different settings for each material so you get tight fitting joints.

== Laserscript LS6090 (80 W) ==

Check '''[[Laser_Cutter#Forbidden_Materials|Forbidden]]''' and '''[[Laser_Cutter#Possible_Materials_(Cutting/Engraving)|Possible Materials]]'''.

* Power range: 1-100 %
* Speed range: 200-400 mm/s ''recommended'' for engraving; higher speeds are achievable according to the [https://hpclaser.co.uk/wp-content/uploads/2019/07/LS6090-PRO-Data-Sheet-2019a.pdf data sheet] [what is the actual limit??]
* Why look at the '''date'''? CO2 lasers loose power over time! New tubes installed: 2020-01 / ...

Here's what we've tried so far - please add your own experiences!

Waiting Lists

2025-07-08T11:51:11Z

MobiTobi:

An overview of the waiting lists for our [[introductions]] that take more time than the [[tutors]] can usually invest spontaneously.

''If you want to "wait" for a vehicle spot, see [[Vehicle Workspaces|vehicle workspaces]].''

<big>'''How to Use'''</big> Please '''link''' your [[Special:MyPage|user page]] at the bottom of each list you're interested in after you've filled it with enough information to contact you and/or activated "Allow other users to email me" in your [[Special:Preferences|preferences]]!

DO: link yourself for the introductions you need for your project(s)

DO NOT: link yourself for all available introductions just because you might need it at some point in the future - chances are you'll forget something important by the time you actually use the machine!

If a list is full enough and/or you have been waiting for a while, please reach out to the tool's tutors and kindly ask for a date - maybe they've just been too busy, but it could also be that they missed the list filling up and would appreciate the reminder.

MobiTobi: /* Material testing */

== Welcome to my page :^) ==

I am now a not-so-new member of the comakingspace.
Below you will find a list of what I am working on and what I have created so far.
When I have made acceptable photos of my projects the write-ups will follow.

So far I have engaged primarily with the laser cutter, 3D printing and Autodesk Fusion.
Next I want to learn sewing 🪡 and improve my soldering.
In the long term I would like to work on expedient furniture, like collapsible desk designs and atlas compatible housing.

I have outlined help pages on creating [[ collapsible_designs | collapsible designs ]] based on reversible tenon and miter joins and on [[Advanced_laser_cutting_pipelines | advanced techniques ]] that made using the laser cutter easier for me.
It will take some time to write the text body. If you want to learn about any of the subheaders ''now'' shoot me a message on slack and I will get back to you.

Also trying to lobby for more morning opening times. Wish me luck 🍀

== Finished Projects ==

==== laser distance gauges ====

==== desk pen organiser ====

==== desk trading card shelf ====

==== speed token for mtg ====

==== fountain pen leather case ====

==== photography light box ====
(backdrop still missing)

== In the pipeline ==
In no particular order

* fans (folded, brisé)
* engraved acrylic lights
* earrings
* deck boxes
* canvas roll-up cases
* Upcycle mint tins with custom linings
* Geometry teaching tools
** pyramid cuts
** geo board

== Materials I have used ==

The full [[Laser Cutter Material Settings]] page has become unwieldy.
For quick reference I duplicate my own laser cutter settings in this table.

Laser Cutter Material Settings

2025-04-26T16:27:07Z

MobiTobi: /* Laserscript LS6090 (80 W) */

[[File:laser setting tests.jpg|thumb|right|200px|aftermath of a [[plywood]] testing session]]
Unfortunately you can't just calculate the perfect settings based on the '''power''' ("Watts") of a [[Laser Cutter|laser cutter]] because the actually delivered energy is always based on a combination of power and '''''speed''''', which is different for each brand or model of laser cutter. To make things more complicated, 100 % power in a cutting profile is not the same as 100 % power in an engraving profile... 

As there is always some trial and error involved, please share your experience with the others! You can often use experience from other machines as a ''rough'' starting point.

In general, cutting is usually done at 100 % power and the highest speed that will still result in a reliable cut. If 100 % speed still gets you through (e.g. paper or cardboard), you should reduce the power until you find the sweet spot. Besides the power setting, you can influence the invested energy by altering the pulse '''frequency''' - you may want to go lower on flammable materials like wood, where edges might otherwise become black, and higher on plastics like [[Acrylic Glass|acrylic glass]] where you are aiming for a "flame-polished" edge. [https://www.epiloglaser.com/assets/downloads/manuals/zing-manual-web.pdf page 46]

The width of the kerf ''(Schnittfuge)'' also depends on the laser settings and the material you're using and could be important for certain designs. [[User:Sebastian|Sebastian]] recommends to use the "DXF for Laser" [[Fusion 360]] export plugin [https://apps.autodesk.com/FUSION/en/Detail/Index?id=7634902334100976871] and testing different settings for each material so you get tight fitting joints.

== Laserscript LS6090 (80 W) ==

Check '''[[Laser_Cutter#Forbidden_Materials|Forbidden]]''' and '''[[Laser_Cutter#Possible_Materials_(Cutting/Engraving)|Possible Materials]]'''.

* Power range: 1-100 %
* Speed range: 200-400 mm/s ''recommended'' for engraving; higher speeds are achievable according to the [https://hpclaser.co.uk/wp-content/uploads/2019/07/LS6090-PRO-Data-Sheet-2019a.pdf data sheet] [what is the actual limit??]
* Why look at the '''date'''? CO2 lasers loose power over time! New tubes installed: 2020-01 / ...

Here's what we've tried so far - please add your own experiences!

MobiTobi: /* Materials I have used */

== Welcome to my page :^) ==

I am now a not-so-new member of the comakingspace.
Below you will find a list of what I am working on and what I have created so far.
When I have made acceptable photos of my projects the write-ups will follow.

So far I have engaged primarily with the laser cutter, 3D printing and Autodesk Fusion.
Next I want to learn sewing 🪡 and improve my soldering.
In the long term I would like to work on expedient furniture, like collapsible desk designs and atlas compatible housing.

I have outlined help pages on creating [[ collapsible_designs | collapsible designs ]] based on reversible tenon and miter joins and on [[Advanced_laser_cutting_pipelines | advanced techniques ]] that made using the laser cutter easier for me.
It will take some time to write the text body. If you want to learn about any of the subheaders ''now'' shoot me a message on slack and I will get back to you.

Also trying to lobby for more morning opening times. Wish me luck 🍀

== Finished Projects ==

==== laser distance gauges ====

==== desk pen organiser ====

==== desk trading card shelf ====

==== speed token for mtg ====

==== fountain pen leather case ====

==== photography light box ====
(backdrop still missing)

== In the pipeline ==
In no particular order

* fans (folded, brisé)
* engraved acrylic lights
* earrings
* deck boxes
* canvas roll-up cases
* Upcycle mint tins with custom linings
* Geometry teaching tools
** pyramid cuts
** geo board

== Materials I have used ==

The full [[Laser Cutter Material Settings]] page has become unwieldy.
For quick reference I duplicate my own laser cutter settings in this table.

Unfortunately you can't just calculate the perfect settings based on the '''power''' ("Watts") of a [[Laser Cutter|laser cutter]] because the actually delivered energy is always based on a combination of power and '''''speed''''', which is different for each brand or model of laser cutter. To make things more complicated, 100 % power in a cutting profile is not the same as 100 % power in an engraving profile... 

As there is always some trial and error involved, please share your experience with the others! You can often use experience from other machines as a ''rough'' starting point.

In general, cutting is usually done at 100 % power and the highest speed that will still result in a reliable cut. If 100 % speed still gets you through (e.g. paper or cardboard), you should reduce the power until you find the sweet spot. Besides the power setting, you can influence the invested energy by altering the pulse '''frequency''' - you may want to go lower on flammable materials like wood, where edges might otherwise become black, and higher on plastics like [[Acrylic Glass|acrylic glass]] where you are aiming for a "flame-polished" edge. [https://www.epiloglaser.com/assets/downloads/manuals/zing-manual-web.pdf page 46]

The width of the kerf ''(Schnittfuge)'' also depends on the laser settings and the material you're using and could be important for certain designs. [[User:Sebastian|Sebastian]] recommends to use the "DXF for Laser" [[Fusion 360]] export plugin [https://apps.autodesk.com/FUSION/en/Detail/Index?id=7634902334100976871] and testing different settings for each material so you get tight fitting joints.

== Laserscript LS6090 (80 W) ==

Check '''[[Laser_Cutter#Forbidden_Materials|Forbidden]]''' and '''[[Laser_Cutter#Possible_Materials_(Cutting/Engraving)|Possible Materials]]'''.

* Power range: 1-100 %
* Speed range: 200-400 mm/s ''recommended'' for engraving; higher speeds are achievable according to the [https://hpclaser.co.uk/wp-content/uploads/2019/07/LS6090-PRO-Data-Sheet-2019a.pdf data sheet] [what is the actual limit??]
* Why look at the '''date'''? CO2 lasers loose power over time! New tubes installed: 2020-01 / ...

Here's what we've tried so far - please add your own experiences!

MobiTobi: /* Materials I have used */

== Welcome to my page :^) ==

I am now a not-so-new member of the comakingspace.
Below you will find a list of what I am working on and what I have created so far.
When I have made acceptable photos of my projects the write-ups will follow.

So far I have engaged primarily with the laser cutter, 3D printing and Autodesk Fusion.
Next I want to learn sewing 🪡 and improve my soldering.
In the long term I would like to work on expedient furniture, like collapsible desk designs and atlas compatible housing.

I have outlined help pages on creating [[ collapsible_designs | collapsible designs ]] based on reversible tenon and miter joins and on [[Advanced_laser_cutting_pipelines | advanced techniques ]] that made using the laser cutter easier for me.
It will take some time to write the text body. If you want to learn about any of the subheaders ''now'' shoot me a message on slack and I will get back to you.

Also trying to lobby for more morning opening times. Wish me luck 🍀

== Finished Projects ==

==== laser distance gauges ====

==== desk pen organiser ====

==== desk trading card shelf ====

==== speed token for mtg ====

==== fountain pen leather case ====

==== photography light box ====
(backdrop still missing)

== In the pipeline ==
In no particular order

* fans (folded, brisé)
* engraved acrylic lights
* earrings
* deck boxes
* canvas roll-up cases
* Upcycle mint tins with custom linings
* Geometry teaching tools
** pyramid cuts
** geo board

== Materials I have used ==

The full [[Laser Cutter Material Settings]] page has become unwieldy.
For quick reference I duplicate my own laser cutter settings in this table.

MobiTobi: added electronics pliers to wish list

A list of gadgets we would like to use in the near future. If you have additional ideas, please add them!

'''For small things, e.g. consumables, we sometimes organize group orders - see "[[Centralized Buying]]"!'''

A good way to make sure something can actually be purchased is to create a page for that item and link it to the entry in this list. That way, we can keep the list neat while accumulating enough knowledge and specific suggestions to make an informed decision what to spend money on. Pages for equipment we don't have yet are in the [[Special:AllPages/Wanted:|"Wanted" namespace]].

Do you happen to know a good source for any of these items, or want to get rid of something yourself? Please let us know!

MobiTobi: /* Optimise your material usage using DeepNest */

== Optimise your material usage using DeepNest ==

https://www.deepnest.net

== Convert your 3D Model automagically to a flat arrangement of 2D shapes using Fusion ==

== Take control of curve approximations using QCAD ==

[[LaserCut 5.3]] relies on the ancient revision 14 of the dxf file standard with limited support for curved line primitives. This can lead to two problems: Either LaserCuts automatic approximation using piece-wise linear functions yields a surprisingly coarse shapes or some splines are ignored completely.

We will demonstrate how to use QCADs explode function to solve both problems and provide the user with control over the approximation fidelity.

Caveat: Librecad also contains a function called "explode", but it refers to something similar to an ungroup function.

MobiTobi: /* Preparing Coffee */

{{ToolInfoBox|tool name=Filter Holder|german=Filterhalter|image=Filter holder.jpg|material=coffee filter size 4|location=Kitchen}}

== Brewing Coffee ==

# Boil Water. While you wait for the electric kettle you can already prepare the next steps.
# Fold a 1x4 filter paper at the lower seam.
# Place it in the filter holder.
# Fill the filter with coffee grounds (~ 2 teaspoon per cup).
# Place filter holder on your vessel of choice.
# Make sure that everything stands firmly and that you have enough space for manoeuvring the electric kettle.
# Gently pour boiling hot water on the ground coffee.
# Repeat step 7 until you have enough coffee or your vessel is full.

=== Tips for Hand Brewing Coffee ===

* If you pour the water too vigorously, the coffee grounds will float resulting in uneven extraction.

MobiTobi: /* Brewing Coffee */

{{MachineInfoBox|machine name=Clatronic KA 3094|german=Kaffeemaschine|image=Clatronic.jpg|assetid=204|synonyms=DE: Kaffeemaschine|material=ground coffee}}

Our Kitchen is equipped with a basic Clatronic KA 3094 electronic drip coffee machine.

== Brewing Coffee ==

# Fill the water tank with as many cups of cold water as you want to prepare
# Fold the 1x4 filter paper at the lower seam and place it into the filter funnel
# Fill the filter paper with coffee powder (~ 2 teaspoon per cup)
# Switch on the machine
# wait for 10-15 minutes
# Remove pot when water stops flowing into the filter.
# Switch off the machine

== Descaling Notes ==

* Use only citric acid-based descaler. Follow recommended instructions.
* Boil and discard fresh water four times after descaling.
* Descale when brewing time increases substantially.

== General Notes ==

* The water tank and the filter holder can be removed for easier filling and cleaning.
* Bring your own coffee grounds. (Left-over grounds might exist in an unknown cupboard from an unknown date)
* The coffeemaker is provided with a drip stop. When you remove the pot it prevents water dripping onto the base. If water remains in the tank it will be pumped into the filter where it can overflow.
