Print output randomly shifting horizontally
Hi all 🙂
Anyone know why this might be happening? It's not the first time it's happened – it's as if between two layers the stepper motor in one axis lost sync so it restarted printing 1mm off in one direction ...
It's quite frustrating as it consigns the print to the bin 😕
Many thanks for your help!
@hogster Which direction?
It could be a variety of things:
1. Belt tension is too low, causing the belt to jump a tooth if the nozzle strikes the part.
2. Nozzle strikes hard enough to cause the stepper to skip.
3. Debris causing the bed to jam.
4. Poor support causing curling causing nozzle strikes.
I would run the X and Y movement tests under Maintenance to see if everything is moving correctly. I see a lot of moire in your print; I suspect your belts aren't tight or there is something else happening that is leading to positioning inaccuracy. Have you cleaned and lubricated the movement lately?
Many thanks for your quick feedback as always Ben 😀
I will do as you've suggested when I have a moment and report back.
All the best,
