When I try to run a job the machine starts up goes to 0,0 and then moves then stuters and the z goes down and I get a 327 Fault. What I notice is that the DRO reads that the machine is at a certain position and it is nowhere near that spot, which is why I am guessing I get the fault. I can’t figure out why it is happening. I can home and jog the machine and even use my ATC. Anyone have some insight? ---

Looks like the issue described here: > [@Intermittent "Drive Fault" error – job stops randomly (EX Controller)](https://forum.avidcnc.com/t/intermittent-drive-fault-error-job-stops-randomly-ex-controller/4602): > > Hi everyone, I’m experiencing a recurring issue with my CNC and would really appreciate your insights. When I launch a job, the machine sometimes stops suddenly with a “Drive Fault” error. What’s strange is that it doesn’t happen consistently — if I relaunch the exact same job, it often works fine the second time. For example, if I run the same job 10 times in a day, it might fail 3 or 4 times. It usually fails when the spindle is plunging and I sometime loose accurate homing, so I always re-h… @Eric helped me with that. We tried many things. Last thing was to update the Z Axis firmware two or three weeks ago. I didn’t get the issue since then but I’m still monitoring because it was quite random. ---

I’m not getting a drive fault. It’s a generic job fault. I think it’s telling the machine to be somewhere and it isn’t. I’m just not sure how to fix it. Strange things was that I was able to run a job but now running into this. ---

Actually, on my side, it started with a Drive Fault. We did a couple of changes in some CNC12 parameters, but then it gave me a “327 Fault: job cancelled”. Then the next step was to update the firmware of the Z motor and now I don’t get this error anymore (so far). Here is a video of the last issue I got: [![](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/f/f5d0346bbd8d322ef7f1a70aa19cad3a4a1f2450.jpeg "Avid 327 Fault") ](https://www.youtube.com/watch?v=O7DtmJp_5L0) And the machine was loosing its home position. I think it really looks like what you are describing. ---

So I just spent quite a bit of time with Ahren on the phone and ultimately we adjusted the z motor in the settings and everything is working again.
