@kickjaw Oh, you have too many objects.

@kickjaw as @alankilian said there is a limit to how many object on the build plate can be named which caused a bug to crash RRF before 3.4b2 it was fixed in 3.4b2:

If the slicer uses the M486 command to label objects in the GCode file, and there were more than 20 (Duet 2) or 40 (Duet 3) objects, then RRF crashed when printing the file

You can upgrade to 3.4b6 or if you would prefer to wait until 3.4 stable then you need to reduce the number of labelled objects.

@t3p3tony

Thank you, is there a way to delete the labeling so it doesn't crash? I will upgrade to the beta either way.

[kickjaw]

@t3p3tony I have upgraded to 3.4.0 b6 and I tired running a different job with a lot of objects again and it still crashed. this on had 100. is there still a limit to how many objects can be on the build plate? I reduced it to 50 and it seems to be running fine.

@kickjaw it should be OK with 100 objects, although it will only track the names and positions of the first 20, and you won't be able to cancel beyond the first 64.

Please post the GCode file with 100 objects on Dropbox or Google Drive or another file sharing site, so that I can try to reproduce it.

@dc42 Hi

Here is the file.

@kickjaw thanks, I'm running that print now on my bench setup. It's running OK so far. How long did it take to crash? Can you post a M122 report taken after the crash?

[kickjaw]

@dc42 It crashed sometime right after the wait for temperatures. I will re run and get the M122

[dc42]

@kickjaw please try RRF 3.4.0beta7 and see if this problem still occurs.

[dc42]

@kickjaw did you test RRF 3.4.0beta7 to see if this problem still occurs?

[dc42]

@kickjaw I'm closing this due to lack of response. Feel free to open it again if you can provide more data, using 3.4.0beta7+4 or later.
