I’m trying to bore hole in spoil board and after spindle spins up positions itself to correct location then just starts to adjust Z axis down it throws that error. I am able to home and jog in all axis fine so I assume it is something with the gcode I generated. How do I debug this?

@DavidB Dis you enable check mode on file load? This runs the file without moving the spindle. So you can see where the error might be.
@DavidB Ran your file. Runs fine for me.
If you are getting Alarm 17 (Alarms List – Sienci Labs), the troubleshooting document points to here: Alarm 10 Warning - Motor Troubleshooting – Sienci Labs (I’m guessing Alarm 10 and 17 are similar enough in troubleshooting steps)
Just tried it again after I had everything off and turned back on again and now it worked?? Why would it just start working after it kept failing on me before?
Now I tried rest of holes and is failing with error 1:
ALARM:1 (Hard limit has been triggered. Machine position is likely lost due to sudden halt. Re-homing is highly recommended.)
Even though I did an “outline” first which worked fine but then when I actually ran it it generated that error after moving about half way towards the front in Y direction.
Then ran it again and worked this time completing 4 more holes but then when returning to home got the hard limit.
@DavidB After power cycling, did you re-home the machine?
Outline does just that, it moves the spindle along the outline. It’s a good test for XY movements but not z.
Using the check file option verifies all axes virtually, including safe height movements.
Why am I missing where the “check file option” is?? 
and yes I would re-home every time.
@DavidB I believe it is under the Basics section in Options
“Check on file open” or something like that.
It threw another motor fault 17 when I simply jogged Z axis manually down a bit. Cleared the error and it allowed me to jog z axis down without issues then. Should I be concerned about this flaky behavior?
Probably.
The document I linked to has another link to this: Motor Components Troubleshooting Chart. It references Y1 but I think it’s valid for any motor.
It might be worthwhile to create a ticket with Sienci. Good luck. Troubleshooting intermittent problems is a pain.
Support is sending a new motor. It is also the only motor that makes a lot of weird noises occasionally. I had swapped cables with the X axis for testing as requested by support and it still made weird noises. I then had to show on the SLB-EXT when it did go into alarm 17 that there was these little tiny LEDs that would show which motor is faulting and it also showed the Z axis. Last item I had to do was send pictures of the top of the motor..
