Random stops during job

gSender ❓ Question
1

Hi team -

I was running a surfacing job this morning (the built in one) and the job just stopped a few passes in.

Console showed the job still running, and all of the motion controls were greyed out, but router wasn’t moving.

I closed and opened gSender, and it seemed normal. I set up another surfacing job, and this one made it further, but it stopped again with the same behavior.

I haven’t had a chance to try a different job yet, and this is the first time I’ve had problems - not exactly sure where to start troubleshooting.

Any ideas or advice? Thanks!

Hello! Have you checked your settings for your USB port? It maybe going to sleep along the way and interrupting the communications between your computer and CNC. Note I didn’t say computer going to sleep, just the port. That, in my opinion would be a good place to start. Please let us know your solution once you find it.

Have a look at this post, may explain it better than I can with only one cup of coffee. USB Selective Suspend in Windows 11 - #4 by Condor00

Thanks! I did make this change, but the problem persists.

I’m pretty sure now that it’s something on the cnc side - either the cable (hopefully) or the controller.

I tried to run a job from my laptop, same results. I’m going to replace the cable and give it another shot this afternoon.

Thanks!

So I thought I had an epiphany - and maybe I still did. The piece I was flattening was zebrawood/epoxy board -not sure if that makes a difference.

Anywho, during the time this job kept stopping, I touched the router and it shocked me a little - static. I read that most causes of random disconnects have to do with RF or other interference with the USB connecting cable. I thought maybe static electricity might be the issue.

I ran over to rockler and got an anti-static dust collector hose, installed it, and got back to work. I had a piece of cherry sans epoxy I needed to cut for a project, so I did that. 2.5 hour total time, no stops, no issues.

Figured I had it sorted, so I got the epoxy board out again to finish the flattening - half way in, stopped again.

So for clarity - it seems to only happen with this epoxy board. Does epoxy generate more static during a surfacing operation? Something else specific to the material?

@timarland Milling epoxy and any of the acrylics definitely creates more static than milling wood. I’m not suggesting that this is the definitive cause of your problem, though.
