Duet3 mini 5+ on CR-10S Rediculously Slow Print Speeds (8mm/s)

[wmccoy61]

Machine has been upgraded to 24V. I have a BL Touch installed and working. I have a BIQU H2 Direct drive Hotend Installed. I am using a 0.6 Nozzle. (Config File at end of Message)
The machine will home all axis in a decent manner no problem. but once I star a print it drops into granny gear forever more... I know it's probably something I have set wrong, but I'm not figuring it out and decided to ask for some guidance. While I am not new to 3D printing, I am new to REPRAP.

Cura Settings ? which ones do you need to know... Don't know how to dump them so I can show them all... But I suspect the slicer is the main culprit here..

@wmccoy61 said in Duet3 mini 5+ on CR-10S Rediculously Slow Print Speeds (8mm/s):

But I suspect the slicer is the main culprit here..

Cura is likely set to marlin gcode flavor and/or your printer profile has some commands in the slicer start gcode section that is setting some very slow speed values.

There was some extra code in the start code section that somehow got put back after I deleted it.. I edited the gcode to verify it wasw gone and printer is much better now/ Thanks!
