This “bug” has happened to me before, but not in a while: Last night while cutting the piece in the attached image (2.5"x6"x12"), the cut would constantly pause. I’m using GRBL with an X-Carve. The rough cut was 1.5 hours, and had no problem/pause. But when the final pass started (same bit, no change/pause), it got maybe 1/8th the way through (just milling back and forth on X) when it would pause. I’d press the ‘~’ button and it would resume. It would go on to do this maybe 15-20 more times over the next 3 hours. It’s obviously super disconcerting to have your cut constantly stopping.
The gcode is 4.6 megs… doesn’t seem too crazy? I was running it at 90ipm… would this have anything to do with it? It has having no trouble a that speed, I could probably go faster (technically).
Any thoughts appreciated!
I dunno about the bug but that is one lovely piece of cnc machining!
@John_Bump : Thanks, appreciated!
I’ve had problems with files larger than about 2 megs. Might be related to the PC I am using (small tablet type). I was doing a laser engrave and had the similar symptoms. Towards the end of the job, it would pause for about 2 seconds randomly. I didn’t have to restart it but pausing during a laser engrave is not good. I switched to a different PC (more powerful) and didn’t have the problem anymore.
I had a similar issue, I cleared my temp files and that helped. Must be a memory issue. How did you generate g code for the mountain range. That is cool.
I cleared my temp files files before the cut since chilipeppr was complaining I was “out of space”. I used meshcam to make the gcode, and Terrain2STL to capture the terrain data. I am using a slightly old MacBook Air to send the data.
@Eric_Pavey very nice piece nevertheless !
i think this is a reported bug with GBRL, I ve got a dirty trick to fix it here in some discussion
@Steve_Scott : Thanks: I used the terrain2stl web app to get the data, then MeshCAM to make the toolpath.
@Phil_Aldrich Interesting: Maybe I’ll steal my sons laptop and see if it has any better results on the next cut
