End of print filament retracting all the way out
-
first week with duet getting somewhat ok with settings, as long as in configuration tool like speeds and direction set ups. but nothing in there for when my print finishes my filament is retracted all the way out. how would a novice find and configure end settings please

What slicer are you using?
Normally this is solved by adding M83 after the G91 command in your end gcode.
Please let me know if this solves your problem.

The usual cause for this is that Duet has been told to interpret the last extruder move as absolute by there being an M82 somewhere, then the last thing in the slicer is to do a retraction of (say 5mm). So instead of it retracting 5mm of filament, it moves the extruder to a position of 5mm from when it was last set to zero. But to be sure, we'd need to the slicer start and end gcodes and your config.g file (or least any M82 or 83 lines that are in config.g).

and that was begining
also for some reason all my prints are being streched longer vertically
think these are my last two bugs to this new setup hopfullyok just learned how to configure file but what do i change
-
I would try changing the M82 to M83 which will change it to relative positioning, it works for me. What slicer are you using?

also besides filament extracting all the way out at end of job the print jobs all stretch parts vertically, i know its in duet someware becouse other printer works fine from repitier sliced files
ok tried changing m82 to m83 in the repetier slicer but than when printed everything was wrong, motors slow and was making mini micro part. cant print nothing the right size
-
If you use M83 in your start gcode you should also select "Relative E coordinates" in the slicer settings.
The reason your prints are too tall will be because your Z steps/mm are set too high. Unless your printer is an Ormerod, i suspect that your X and Y steps/mm are wrong too. Find out the steps/mm for each axis and put those figures in the M92 command in config.g.

turned out was my step setting for E motor, the filament retraction as well as my stretch problem, instead of just retracting few mm it was retracting a foot, now with right setting just backing off pressure at end of print like sopose too, thank you everyone for replying to my petty problems but is my first week in the 3d printing world.
