Hi folks,
I’m looking for help as I’m running out of ideas on my z-banding issue, see picture.
I lubricated all rods and spindles, adjusted Vref for the extruder (Titan direct), it’s not skipping. Hotend is free of debris (several cold pulls performed).
There seems to be some kind of regularity in the distance of the Bands.
Anything more I could check?
Thanks in advance.
is it a heated bed? if yes what power supply do you use?
belt tensions possibly?
Temp variation cycling perhaps. Execute PID to prevent huge variation of hothend temp.
@Chris_Bigpaws_Chambe belt tension is good
@Cristian_Nicola Yes. Standard switching power supply
@Lio_Nel did that prior to the print
@1111161 it’s a p3steel frame
Normally when I see z banding I go to the z rods, however that is too wide of a band for me to think it’s the rods. I would lean towards heat bed temp fluctuations
Are you sure that the lead screws rotating straight. From the mark looks that you have 8mm pitch.
When I see the difference in banding height, especially around the big hole, I have the impression it has something to do with the spool. Did you already tried an other spool?
アイテムの反対側の画像も見せて欲しい。Z軸のスパイラルのシャフトが歪んでいるのかもしれない。
それを回避する方法はあったりする。
Does it do this with different types of filament, what about filaments from different suppliers? It could be a symptom of periodic non-uniform diameter filament.
A high-res image would help a little I think. However have you double checked vref on Z? I guess it could be a driver/motor overheating periodically. Otherwise could be heated bed temp variances. Print with heated bed off is a simple test assuming you can get it to stick.
@Griffin_Paquette how does heat bed temp affect layers that far away from the bed?
A picture of the machine here would be useful here.
If you aren’t using PID on the bed, you should enable it and calibrate.
@Stephanie_A I do

@David_Sherwood that somehow makes sense. But the period between the potential partial jams seems too regular for me. Any idea to improve?
