Compressor motor turning on and off is cutting out my cnc spindle

There is a general consensus on the forum that USB interfaces are more susceptible to electrical noise than ethernet, and general advice is to chose ethernet over USB for this reason. However, no-one here can state whether this would fix your issue (I suspect it'd certainly help).

First things though - can you not try to dampen your electrical noise - get some ferrite filters for your compressor (remove noise at source) and IEC leads for your CNC get-up. <- that might not be very effective - yeah, some noise when switching an induction motor on/off, but not as much as a brushed motor.

A UC300ETH would, as well, open you up to try the UCCNC software, rather than Mach3 - I for one much prefer this, I know this is a view shared with others.

Thanks Doddy, how simple of a process is switching over the controller?

I'd like to move away from the cracked mach3 that came with the machine asap.

My only worry is getting is all setup again in UCCNC, or a new mach3 license because I have no clue and the cracked mach3 that came with the omio had everything setup ready to go/
