Multicolor Prints produce negative values for certain G1 F commands right before the M600 command

HitLuca commented 2 years ago

What happened?

I was trying to print a multicolor calibration cube, with M600 filament changes at specified layer heights, but my print failed. Debugging the issue led me to find that right before the M600 command, the slicer produced a bunch of G1 F-2147483648 entries, which to me look like integer overflows.

my gcode file is here https://www.zerobin.tk/?166135e858db7cc6#2Lp3Y71PBkizREedCPnnhmrUC8sYCKGhK4wkoixj6j5w and I can reproduce it consistently with new multicolor prints.

If needed, I can add my printer configuration file since I don't know exactly what is embedded in the Project file I attached below

Possible workaround found and added as comment on the linked Prusa Slicer issue

I am having the very exact same issue when using color changing commands such as t1 t0 t3 and so on. Those various commands work fine on their own. My print fails just before the t command and gives this exact error and my g code is showing the exact same negative values. I will try to test this workaround to see if it successfully allows me to do a color swap. This is very frustrating as I have tested various versions of prusa as well as super slicer. I am using SMuFF V6. All macros for the printer and SMuFF are functional including park_toolhead. Also using klinky with no issues.
