Hi all, yes, I checked it in bugfix 2.1.x. Problem is remaining.
See file https://github.com/MarlinFirmware/Marlin/tree/bugfix-2.1.x/Marlin/src/gcode/feature/pause/M701_M702.cpp and compare line 122 and 225, please.
Best regards David
Did you test the latest
bugfix-2.1.x
code?Yes, and the problem still exists.
Bug Description
The final Z-position after M702 completion is incorrect when upper limit of Z may is to be exceeded during filament unloading process. The similar command M701 was modified in this fix: "Fix Resume Print with UBL (#21564)", the M702 code still unchanged. The M701 working correctly, M702 do not.
Bug Timeline
It is old bug, it was partialy solved in 2.0.8
Expected behavior
The nozzle will travel to the upper limit (less than the value in the Z parameter), unload the filament and return to the same position as before the command.
Actual behavior
The nozzle will travel to the upper limit (less than the value in the Z parameter), unload the filament and go down by value in Z parameter. The final position is deeper than before the command.
