@Phaedrux I will make a video later as this huge printer is now printing, but let me try to describe the steps clearer:
start print pause in the middle of the print. wait until paused. 10mm retract occurs as it should. print is now paused. resume the print. unretract (extrude) of 10mm happens accordung to resume.g. This has no effect because it was retracted before. printer now extrudes another 5 to 15 mm for no reason, very quickly, much quicker than the F rate specification of the respective command in resume.g printing resumes with an ugly blob. this happens almost every single resume.
