I just installed a new set of the next gen linear rails. When I print now, the prints are “slanted”, by which I mean that every new layer moves forward on the Y axis. The bed is not shifting during print, and bed adhesion is excellent. The rails appear to have full range of motion - the head goes to the top left, then homes correctly to the bottom left, and appears to move up correctly during print. The bed moves on the Y axis using the controller to the full length. There are no unusual noises, no catching, no jerking in motion.

I’ve used both newly sliced models, and models that were previously sliced and ran successfully and both have the same issue.

Any help would be appreciated.

There was another user with this issue a little while ago, let me see if I can find it. Is this what you’re seeing?

> Hi all, so the issue was that I pulled out the black sensor from the 3d printing head too much. I tucked it in and it worked. Snapmaker also suggested the following, but when I checked, this was Ok for me. For sure, if you take the 3d printing head down, be sure to turn off and restart the printer. It is probably doing some extra checks and that’s how you can avoid trouble. ———— The issue is caused by the Y-axis linear modules. Here are the steps for your reference: Dismantle the heated be…

This is resolved. For anyone who comes along later, I did a factory reset on the machine, and that solved the problem.

Hypothesis: I ran a calibration set on the machine after replacing the rails, and saved some settings directly, One of them was probably bad.

I don’t think so. Resetting to factory settings solved id.
