M82 - E Absolute Failsafe

Open Fienberber opened this issue 3 years ago • 0 comments

I was finally trying the calibration tool but I got issues with the GCODE generation.
The problem came from the M82, E absolute mode used by Simplify 3D. In my starting GCODE, I prime the nozzle but I use a G90 command and it reset the M82 setting.

That causes my nozzle interprets absolute E position with relative ones. So it extrudes exponentially until the end of each layer. After a few layer the print obviously fail trying to extrude 13mm of filament within 2mm.

I found the issue quite quickly but I think it could be a good failsafe to run a M82 command after the "custom start" gcode. Since at least PrusaSlicer relative E it can be that other user face this issue importing their own start and end gcode (Prusa default prime line use G90 as well).
