We are experiencing similar issues and I was reading along all these threads. @Starla, if you want me to open up a new one let me know.
Mostly during engraving, but also noticed with cuts, we have drop outs. The console reads “disconnect”, the machine homes but our air-assist stays on weirdly enough. To me it feels like a reboot of the laser motherboard, but unfortunately I cannot find an uptime function in the commands (or is there?).
Due to our large bed (1200x1200mm) we have engraving jobs that easily go over half an hour and if they drop out half way, we can throw away our sheet…
Stuff we’ve tried:
- encase the motherboard in an aluminum box as RF shield
- switch to a different 24V power supply
- Get the whole machine on a 3-phase connection, so now the motors are phase 1, motherboard phase 2, and laser powersupply and cooler are phase 3
- We suspected the water cooler causing a ripple in the line when switching on/off, so we’ve placed a line filter on the 3rd phase

All help is very appreciated! Feel free to ask any question or more info that is required
