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](https://sienci.zendesk.com/hc/en-us/articles/33321741516436-Alarms-List)), the troubleshooting document points to here: [Alarm 10 Warning - Motor Troubleshooting – Sienci Labs](https://sienci.zendesk.com/hc/en-us/articles/36090373125396-Alarm-10-Warning-Motor-Troubleshooting) (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? ---

@DavidB > [@DavidB](#): > > Should I be concerned about this flaky behavior? Probably. The document I linked to has another link to this: [Motor Components Troubleshooting Chart](https://sienci.zendesk.com/hc/en-us/article_attachments/46183514330004). 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..
