A CNC mill is similar to a CNC router, but usually more precise and designed for smaller workpieces.
|Material:||just foam for now|
|Used with:||1/8" endmills|
|Status:||working out initial problems|
|Software:||CAD/CAM software (e.g. Fusion 360); G-code sender|
|Similar (More or Less):||CNC router|
- 130 × 90 × 40 mm working range (less Z freedom depending on the length of your endmill!)
- there are no endstops
- manually home the mill before a job
- you should use the (X/Y center, Z surface) as your origin
- make sure the size of your part does not exceed the working range!
- motor speed: ???
- compatible shaft diameter: 1/8" (3.175 mm)
- controlled like the CNC router (Fusion 360 or similar CAD/CAM software; G-code sender)
- connection via USB - bring your own laptop!
The current solution is not ideal, but many the workholding options for our larger CNC router should also be suitable if scaled down.
- figure out motor speed to calculate proper feedrates
- what else?
- screws/nuts used to come loose due to vibrations
- fixed with loctite or counternuts (where possible)
- Z axis used to be too hard to turn => mill drifted deeper and deeper into the workpiece as upwards movements failed but downward movements were still possible
- was caused by a faulty spring
