Hey y'all, I managed to hack together a printer from scratch and I'm struggling to get it to print well. It's a CoreXY system that's being controlled by a Octopus 1.1. Dual z screws, the works.
I have it moving under it's own power and all. It's able to actually print, but the results are atrocious.
I'm just trying to diagnose what's wrong here.
The bottom/first layer actually looks kinda good. It's just completely shredding subsequent layers.
Any advice would be appreciated!
It looks like you're under-extruding and/or clogging. If you can get filament through your nozzle in air, but not while printing, I wonder if you have enough tension on your filament? Extruder emperature variation as you move around might be another possibility. Not moving correctly in z would cause your parts to mushroom and is easy enough to check by homing, moving the nozzle to say z10, and then measuring the gap.
Good luck!
