Hello smoothiers,
I’m having terrible issues with my 3D printer. When I print, the extruder nozzle collides with layers that have just been laid down. I see the z axis rod threads rotate, but they don’t rotate enough to avoid the previous layer. I’ve been trouble shooting this for 2 weeks. What is going on?
This is my setup: Printer - Rigidbot Regular with 10x10x10 build volume
Motherboard - Smoothieboard 5xC v1.1 with 1/32 micro-stepping, latest firmware, config file
My z motors have a step angle of 1.8 degrees, 1.68amps, and rods with 12 tpi or 2mm pitch
My config file:

Yes, I can manually operate everything.
So this is currently what my printer is doing after starting a print. My previous config file had me cutting the steps per mm on all my motors in half so I could “trick” my printer into even getting a first layer. So with my current config (with all the steps per mm as they SHOULD be) this is what happens…why does everything get so out of wack?

Your acceleration values look way off.
I’d suggest lowering it to 1000 for X/Y and 500 or even lower for Z to start with. You can raise and tweak those values later when you’re fine tuning your printer.
It’s working WAAAAY better. Finally got to print a half decent calibration cube. The problem seemed to be my bed level after all, but I will fix the acceleration as you said. Check this out though, the last few layers came way off from the print, wondering what went wrong. I’ll keep trying. Thanks guys!
