This self-built CNC router arrived at the Space in early 2025 and waits for your help to shine ;-)
This tool is not ready for use yet since not all commissioning steps have been completed. The process is also tracked on GitHub. Feel free to contribute to making it usable, any help is very welcome!

This page is specifically for the Blackbox CNC router, first read the CNC Overview page to get some information common for all CNC routers and mills.
All information on this page are preliminary until verified and the Blackbox router is being released to public.
Introduction
to be entered soon.
CAD / CAM
A "grbl" post processor is being used. If you are using FreeCAD follow the guide in this link for the exact settings. If you are using Fusion360 follow the guide in this link.
The Blackbox CNC is much more stable than the Workbee CNC due to the way it is constructed. Nevertheless practise on cheap material to get to know the limits of the machine.
Until more experience exist you can use as a starting point the same speed parameters as for the Workbee, but this machine should be able to handle higher speeds.
Start with
- 2mm depths per round
- speed a good starting point is 600 mm/minute.
You can read some more details here WorkBee Schnittdaten und Fräser . Eventually this page will be extended once enough experience is available
Router
The router mounted to it is a Mafell FM800 [1]. You need to consider the sizes of its collets (Spannzangen) when buying your router bits.
- no-load speed: 7000 - 25000 rpm
- max cutter diameter: 36 mm
- available collet diameters:
- 8 mm
- 6 mm
- 3 mm
RPM Chart
The RPM value is set on the router via a dial, settings in the g-code are not obeyed. You can change the router RPM value during operation if needed.
| Dial Setting | Approx. RPM |
|---|---|
| 1 | 7000 |
| 2 | 10600 |
| 3 | 14200 |
| 4 | 17800 |
| 5 | 21400 |
| 6 | 25000 |
