[SOLVED] Layers not aligning on Y
Hi all,
I've recently bought an Original Prusa MK3 kit, it's my second kit printer and I just finished assembling it.
The printer autotest ran without problems giving all OK, the first layer calibration also ran flawlessy.
But when I started my first prints I've noticed there is an align problem on the Y plane
The one on the right is with Crash Sensor turned ON (you can see the Y slide on the bottom part below PRUSA), the second one is in Stealth mode, so without Crash Sensor and it has those zigzags at the bottom (still Y slide)
On this side image the Y slide is more evident
I'm running on the last Firmware, I tried both Slic3r PE and Simplify3D and they get the same error
I checked the Y belt tension and they look ok with the pulleys free to move
I'm using the magnetic steel plate
Any ideas?

Thank you,
Robert
Re: Layers not aligning on Y
Loose belt, loose grub screw on motor pulley, u bolt too loose or tight.
Re: Layers not aligning on Y
The belt look ok, not too lose not too stiff, the grub screw is firmly on the motor, what puzzles me is that the problem appears around 2-3 layers and then disappeat 😮
Re: Layers not aligning on Y
Today I had the time to run a close inspection to the printer
Turns out it was really a slightly loose grub screw, coudn't see it at first glance
