I used my SO5 last night and all was fine. I came out today and go to run a job and the spindle won’t start. I reinitialized it, turned everything off and back on, shut it all down and even unplugged everything. There is no error message in CM. I know little to nothing about VFDs but I did notice that if I press the JOG button the spindle starts to spin. Pressing the >> button I see the V values as 4.78, 0.0, & 177.6.
I tried some of the steps I found in the forums and /M3S18000 does nothing. The log shows:
[GC:G0 G54 G17 G21 G90 G94 M3 M9 T0 F50 S18000]
I don’t speak GRBL so I don’t know what that means though.
Also here are the other values that I think are useful:
I also checked the voltage on the spindle output and I do see 3.3VDC for a M3S18000 and 4.96VDC for 24000. It drops to .127VDC when I send M3S0.
