Z axis canted

Heyo,

I've run into a rather weird spot. I've test printed a 60x60x100mm box and I noticed that the top seemed shifted. Further measuring on the printer confirms that the entire Z axis seems to be tilted towards a couple of degrees, so it actually prints level, but shifts a couple of fractions of a millimeter forwards with each layer. Any tips on what to do about this?

Thanks!

Cheerio,

Thanks!

Maybe I'm blind, but that doesn't actually help me. I've measured my bed against the Y axis rods with a water level and they're parallel according to my water level.

However, the Z axis in its entirety is not, its canted slightly forwards, as explained, resulting in minimal layer shift with each layer. The printer is unable to detect this and thus vertical surfaces that should be squares are parallelograms. The deviation seems to be at about 1mm per 100mm.

What was the result of check 4 under the YZ-axis heading on that page?

Cheerio,

both rods were touching the steel sheet on the left, while on the right ( i.e. near the Z tower) there was a minor gap between the lower rod and the steel sheet.

That sounds like a minor twist - go through the process at step 5 and try to level it across the whole width.  Once they are the same go to step 42 on: https://help.prusa3d.com/guide/2-yz-axis-assembly_196824 and the following steps.  Check the Z connections have not vibrated out of line;  loosen each half a turn, wiggle into place and retighten.

Cheerio,

I loosened pretty much every bolt related to every axis, then retightened them all according to the manual and now the problem seems to be gone.
Thanks for the help though!
