@1ri I put this M code in the config or in each gcode?

@bearer great thanks I will try.

Recently I start a print and my slicer told me arround 21Hrs, I know that is not the right time, it took less then 21Hrs. Is there a way to see the printing time after the is done?

the problem is fixed. Thanks for all your tips very helpfull.

@fcwilt when I use M83 when I print my extruder push too much filament, on my bed it's look like a big amount of melting filament. You suggest to use the M83 how can I fix it, is it in my config.g or in my slicer that I have to modify something?

@deckingman You give me a good hint. In see in my config.g I've put the M83 in comment instead of changing it to M82. I will remove the comment and put M82 and see if that fix my problem. Thanks

At the end of my print my extruder goes backward and unfill my bowden tube. I've install my Duet2 wifi 5 days ago and before the switch I never had this problem. I didn't make any changes in my slider. Any idea why?

Thanks
