This page is INCOMPLETE and still missing some important information before it can be used as a resource. Please use the "Discussion" feature above or talk to one of the tutors if you would like to help improve it. Thanks!
This is the content required for an introduction to our CNC router - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)
Before you get this introduction, please make sure you already have the Handheld Router Introduction, this will help you understand the machine much better and is required before using it.
Let's begin! First off, make sure you have read the machine's manual, if available (check its "InfoBox" in the wiki for instructions how to find it).
Safety
Dangers
- sharp, fast spinning bits (end mills or - rarely - certain router bits)
Precautions
- wear personal protection
- stay clear of the CNC router when in operation
- unplug the router when changing a bit or touching the chuck for any other reason
- monitor the CNC router closely when in operation
- push the emergency shutdown button if anything goes wrong
Suggested Reading
Besides these safety notes, you should read about the different end mills (and router bits, if you want to try those) to know what you're doing! Different materials usually require different mills, and the feedrate depends on the mill as well as the type of material.
Demonstration
The tutor will show you these steps in detail:
- at the machine
- selecting the right bit
- inserting a bit
- turning the machine on and off (easy to forget!)
- on a computer
- generating G-code from a design in Fusion 360
- uploading the code to the CNC router
You should then be able to do a small practice cut.
Temp Notes
Please use gcode sender nightly (some what stable ugs classic interface)
In gcode sender: first click on $h for home Xy step size 100 Z step size 1 Feed rate 4000 Use x/y +- to navigate close to your ursprung Lower step size Use x/y +/- to navigate exactly to your ursprung Use a paper to properly figure out the correct Z position. Note down the coordinates (in case something goes wrong)
