We need to start to fill up lemmy :) Can you solve this issue?
My HEVO (Hypercube Evolution), now 5 years old started to have very weird banding.
It has a Bowden BMG Extruder and a E3D V6 printhead with CHT-Nozzle. MKS Robin with TMC2209 and Klipper.
Benchy is ABS, lower one is HIPS. Printed at 230°/105° bed. part cooling fan off.
I took apart and cleaned the extruder. The gears look intact and i can move the extruder by hand without binding. I found the E3D V6 was loose. I retightened it, which didn't solve the issue.
I'll spend a beer to the one that solves this issue ;)
Edit: Found the Issue: hotend not hot enough.

Heyyyy HEVO brother!!!
Have you dried your filament? Also make sure the X rods don’t bend around or the nozzle/carriage isn’t loose.

Heyouu :) Nice! Showcase your printer? Here's mine.
Yeah my filament is stored in dryboxes and I janked the carriage around, it's fairly stable, no unusual flex :(.
I'm going to make my newly built DuelingZero ready for printing tonight then I can finally fix my HEVO :) I plan on Upgrading to the Hextrudort, which will hopefully fix my issues. Upgrade path ist step by step to a complete hevORT :) let's see how that goes.

I présent to you Bumblebee!
I use this carriage and the rail x gantry from the same designer.

Have you printed that blue spool before at that temp? Do you use any cooling?
My ABS kinda looks like that if I forget the fan on, or have a too low nozzle temp.

I usually don't use cooling for ABS as it leads to bad layer adhesion in the final part. But ABS should print perfectly fine without cooling.
Hmm... I print at 230° which was enough in the past, maybe my thermistor is reporting the wrong temp?

You found solution?
Do PID tuning if you changed anything or you might have wrong or unstable temps. I dont print much ABS but I think its safe to use part cooling fan at lower speeds. Picture looks like you are printing too hot

Hey thanks :) Yes I found it. It seems like I printed not hot enough. I am now printing at 250° without issues anymore.
