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!

    You z-step might be off. I.e. z is moving too far each layer.

      I realize I’m reviving a super old post here, but I actually did end up figuring out what it was. I posted a little writeup in here if you’re at all curious. You were actually kinda close.

      I think you might be onto something but the other direction. I think it’s not moving quite enough per layer.

        You could try moving Z to +100mm and just measure with a ruler to make sure it’s at least in the correct range.
