Job consistently fails with Alarm:17

Hi,

I’m having issues running a job. Every time I run it, it fails after the sixth helix cut with an Alarm:17 error. I searched the error online and I get conflicting descriptions. one source says it’s "Laser mode requires PWM output”, and another says "ExecAlarm::GCodeError” (which seems the more likely candidate since I have not lasers).

I created the gcode in FreeCAD’s CAM workbench using the same postprocessor that I have used successfully on other jobs.

Things I have tried/tested:

  1. Adding padding to the stock in FreeCAD in the X and Y directions. My thinking was that it was somehow going into “negative” space and this might resolve it. Nope.
  2. Running the job in the air with vaccuum and router off, just cuz.
  3. Checked grounding of vaccuum hose with multimeter. it is connected to ground. this also seems unlikely to be the issue since it always fails at the same point (i.e. the problem is not intermittent)
  4. Switched to my home WiFi, partially cuz I wanted to do this anyway, partially to see if it had to do with a device connecting and/or dropping from the AP. Again, a Wifi issue seems unlikely to cause a failure at exactly the same point every time

I have attached the actual gcode file. It’s right around line 123 where the Alarm is triggered each time. I opened the gcode on ncviewer.com and it displays and runs as expected. I also attached the FreeCAD file and a screenshot of the terminal output shortly after the Alarm was triggered.

anyone have any ideas?

I think it might be that I didn’t define a feedrate for the drill operations (it helps to actually read the error messages :roll_eyes:). I can’t test right now, but I’ll reply whether I have success later tonight.

Missing feedrate was the problem :man_facepalming:

Looks like it’s time to create a template for Mr. Forgetful
