Gcode from version 2.4.0 but not 2.3.3 causes printer error

[Heindal7]

Prusa Version

2.4.0 but not 2.3.3

Operating system type + version

Windows 10 Pro 21H1

3d Print Server

Repetier Server 1.2.1 on a Pi Zero W

3D printer brand / version + firmware version (if known)

Anycubic Vyper 2.3.3 and 2.4.5

Behavior

Printer stops mid print by traveling straight up in the Z direction about 20mm and stops responding to further G-code. The issue doesn't not occur in all prints. When I repeated a print with the issue, it also happened on the second run at roughly the same location. It also repeated when I re-uploaded it to the server. It has always happened (all six times) near the a perimeter of a hole and doesn't occur after the same duration of time on different prints. It happened on layer 14 of the printing of the attached file at about line 11868. tibia_l_0.2mm_TPU_33m.gcode.zip I have stopped using version 2.4.0 and have not had any issues on other slicers.

Only thing I see in that location is the following for the first colour change. ; AFTER_LAYER_CHANGE 13 @ 2.9mm ;COLOR_CHANGE,T0,#21DA30 M600

Try editing out the # from there and printing. Its possible your printers gcode parser cant handle that character. Theres also one on the second colour change so best to edit that one out too. Or you could move that comment line further up in the code and see if the printer doesnt like it at that point.

Isn't that normal behavior of your printer after M600 command?

Maybe you just added color change accidentally?

[Heindal7]

I followed your suggestion and moved the M600 command earlier in the file and that triggered the issue. That solves part of the issue even if I now know the color change command is buggy on my printer.

I rechecked the stl files that had the problem. Sometime when it finds a file that it thinks is a logo, it appears that the slicer is automatically adding color change to my prints when if I don't select the apply color change automatically. Worse than that once it happens, it appears to think all future files I load are also logos (even if it doesn't normally) and continues to apply the color change to them. If I close and reopen the program, it stops thinking everything is a logo and goes back to doing everything as a single color.

PrusaSlicer will only apply the automatic "color change" to your model if you click on the hyperlink "Apply color change automatically".

Closing. There are no similar reports, it could really have been caused by inadvertent addition of a color change.
