Bondtech X2 tremendous under extrusion error

engikeneer

@thedragonlord you will want to use some small amount of pressure advance to help your corner bulges. Most of the under extrusion starts at them so lack of PA is only exacerbating your issue.

@engikeneer Orange material is PETG...I'll try to set a little PA but I don't think it will solve the problem

@thedragonlord worth trying a different slicer? does printing at a higher temperature make a difference?

I'm downloading Prusa Slicer to try and no, higher temperature doesn't change the issue.....

Same issue with prusa slicer.....

@thedragonlord What retraction setting do you have in your slicer?

"RepRapFirmware does not support individual motor settings where an axis has multiple motors connected to different stepper drivers. The first parameter specified will be used for all motors on the axis. "

I don't know if there's an exception for extruders.~~~~

Edit. Yes, there is :-)

@gixxerfast extruders are treated differently

@jay_s_uk Thanks, I sort of guessed it. Would be weird otherwise with all the different multi extruder combos that people have. I'll edit my response above.

@thedragonlord just a thought did you work out your extrusion steps cold or hot? I`m thinking along the lines of narrowing down the cause, cold and the fault is most likely hot side etc....

hot

@thedragonlord well what goes in must come out, and if the under extrusion is occurring on both nozzles it would be my guess its software/firmware related, maybe try someone's working config file both firmware and slicer for testing/comparison?
