X-axis layer shifts

I just built my kit, this past week. After initial calibration, things seemed OK. I printed the planetary gear, Prusa logo, and Buddy files from the SD with no issue. I printed another planetary gear, and noticed that there were layer shifts in the print. I checked the belt tensions, and they feel OK. The calibration menu shows that X and Y are both around 265. It's not always the same layers, and I even get this shift on layer one. The printer also shows no crashes detected in the Support menu.

I printed the 3x3 bed height calibration to see if this was happening only in a certain area, and because I had yet to print anything that had a very large print area.

I've been trying , all weekend, and just cannot seem to figure it out. 😔

RE: X-axis layer shifts

Hello,

I would verify how the screws of the X pulley are tighten on the X axis motor. You need to tighten first the screw on the flat part of the X axis motor and only after the second screw of this pulley, otherwise the pulley could rotate around the axis and create layer shifting.

Good call. I double-checked that, and it also seems OK. Both screws give enough resistance that I'm skeptical about trying to turn them any further.

Turned off crash detection, and every print since has been fine.

RE: X-axis layer shifts

Does your X axis move  smoothly by hand? 

If there is any uneven resistance it could be seen as collisions... 

Did you lubricate your smooth rods during assembly?
