At the start of print, I have a sudden shift in my print. The belts are not loose at all, so I don’t understand what the cause is. Here you can see the video:video
Does the sliders move smoothly?
Do you feel sudden resistance?
The sliders moved, but not very smoothly. I added some extra fine oil, and now it runs fine, thanks.
I have encountered another issue. Sometimes, with a fast travel form one point to another, the printing nozzle scrapes over the printed part, sometimes resulting in magnets of the print head detaching from the rods. What can I do to solve this?
Hello Scalle0479,
Check your first layer this if very important. Not too deep or too high in Buildtak.
If not oke => calibration is not oke. So go through this troubleshooting guide:
1. 3D printing tips § Calibration issues. Check every step and adjust were possible.
Note:
Degrease the bed each time before printing, and do this on both sides as the bed level sensor rely on a clean surface to work properly. Also a clean Buildtak sheet works much better.
For “nozzle scrapes over printed part” You can follow this topic to solve it: Scratching surface when travelling - #32 by Arthur - Software (Repetier & Cura) - Whadda forum - Community Help and Support
Use also these “travel” settings:
Use also the Ultimaker Cura software for slicing the 3D models: UltiMaker Cura It has a newer engine than Repetier.

Hey,
Thanks for the tips! I’ll try them later today. If the problem still persists, I’ll come back to you.
Kind regards!
