These are a few Q&A that I think may be more common while using µCNC.
- In terms of collisions I think it's has safe has Grbl. Always wire the ESTOP input and it shuts down everything as soon as you press that button. Limit switches triggered with hard limits enabled also prevent unwanted axis crashes.
- In terms of quality of work v1.2.0 is (I believe) capable of deliver reliable results. In any case safety precautions should be implemented. Run the code in check mode to check for GCODE errors and incompatibilities. If still not confident, do a dry run on a scrap peace or in the air to see if everything looks ok. Then run your real job.
- With minor adaptations yes.
- Pinout yes.
- In terms of settings configuration $0 is max step rate and not step pulse in ms, so for UNO the change is from value 10 to 30000. Everything else should be ok. Eventually $5 and $7 may need adjusting for inverting the limits and controls inputs depending on your wiring.
- If you installed the precompiled version available here then the startup message is with the µCNC name. Some interface software (like Candle, Candle2, and UGS) expect the Grbl startup message instead. If so µCNC needs to be recompiled with option EMULATE_GRBL_STARTUP enabled (cnc_config.h).
