Extruding blob after (custom) pause

Recommended Posts

Posted · Extruding blob after (custom) pause

I created my own 'Filament Change' plugin, as the ones in Cura (FilamentChange and PauseAtHeight) both seem to have issues.

My plugin inserts the gcode as I want and it works pretty well.

But, after it resumes printing, the printer starts by extruding a large amount of filament on the starting position on the object.


No idea why it does that, as I do a Extruder reset before the end of my code

G92 E0 ; Reset Extruder

Anyone any idea why this is happening and how to solve it?


Here is a snippet of the full gcode:
