After assembling and installing my MK3 on my Ender 3 pro (modded to have direct drive) along with following all the necessary gcode and slicing procedures in prusaslicer, my printer will start the prints about a cm up on the build plate and no filament will move through the extruder. Here are a list of variables I have tried to narrow down the problem:
Leveled bed while heated with auto home to prove my bed wasn't ridiculously off, to no avail
Ran the same gcode on the printer without the chameleon, print worked normally
Checked to make sure I had actually used the correct gcode in the correct placement, even re-generating and repasting the gcode with the same values, to no avail
Tested the switch and motors manually to proved they weren't dead, both were fine.
Ran a print in cura with no special gcode, to narrow down hardware vs software. Issue still occured on both fronts (x gantry too high and not extruding)
Ran cura print again without 3d chameleon attached (just filament inserted directly into extruder) and the print did just fine
Does anyone have a possible reasoning for this and or a fix? Thank you!
I think I'd need to see your gcode. The 3DChameleon doesn't interface with the printer at all electrically or via the firmware, so it can't possibly the be the cause (unless the tubes or something are binding, but on an Ender 3, I doubt it) and we don't ever change the Z height in our gcode, so there must be something else in it. Maybe a missing line or something? And since it's starting at the wrong height, and our code doesn't inject itself until the Tool Change GCode, I'd think that it's possible that the start gcode has a bug in it around the Absolute vs Relative positioning... check for the proper mode via G90, G91 and M82, M83. That's the only thing I can think it could possibly be. (Compare the gcode between the two, with 3DChameleon and without.) Can you send me the file you're trying to print (the gcode) and I can take a look at it and run it though my printer to see what it might be?
