This is a heavily modified fork of https://github.com/martindb/mpcnc_posts_processor focusing on making the post-processor better for Marlin-based MPCNC routers.
CAM post-processor for Fusion 360 and MPCNC with RAMPS or other Marlin-based control boards. Supported firmwares:
- Marlin 2.0
- Repetier firmware 1.0.3 (not tested, but gcode is should bne the same as for Marlin)
Some design points:
- Setup operation types: Milling, Water/Laser/Plasma
- Support MM and Inches units (but all properties MUST be set in MM)
- XY and Z independent travel speeds. Rapids are done with G0.
- Arcs support on XY plane
- Tested with LCD display and SD card (built in tool change requires printing from SD and LCD to restart)
- Support for 3 different laser power levels using "cutting modes" (through, etch, vaporize)
- Support 2 coolant channels. You may attach relays to control external devices - as example air jet valve.
- Customizable level of verbosity for comments
- Support line numbers
| Title | Description | Default |
