At each layer start there are some odd gaps.
Any idea what could be causing this? Maybe too much or too little retraction during travel?

#

this is most likely underextrusion

Underextrusion?

#

either your extrudr config is very slightly off and you should change it or you can adjust flow rates in the slicer

#

not enough plastic coming out of the hotend

#

Oh cool cool, how do I test / tune for that?

cinder stratus Jul 22, 2024, 4:33 AM

#

you can just up the flow rate in klipper and see how prints turn out

#

Flow rate? Like the rotation of the extrusion motor?

cinder stratus Jul 22, 2024, 5:12 AM

#

yes

#

#

"extrusion factor"

#

do like 105% and see what happens

#

Ah okay, but when savingit in the actual printer.cfg do you save it with rotation rate? I don't see extrusion factor anywhere

#

#

"rotation_distance"

#

this is just an example from my v0 don't use that number
