Mini 1 having strange layer shifts

I have a mini 1 that has been working great for years. It has recently been doing a really funky layer shift thing. It has an aerostruder hot end. I have had that hotend for a while. I did recently add a motor damper to the y-axis. Any thoughts on what I should check? The cura screenshot is for reference of how it prints.

If your shifts are occurring mainly along the Y-axis, it’s going to be related to the mount or the belt tension. Reach out to the support team for assistance at https://LulzBot.com/Support. If you don’t mind, reprint your model, leave it on the bed, and take a picture of it, to help determine which axis needs the most attention.

will do

If the shifts are in the Y-axis, and given that you said you just added a dampener to the Y axis, re-check the set screw on the Y-axis pulley. A loose set screw or loose belt tension may be the culprit.

Hello ! I have a Lulzbot MINI for a few years. I changed recently the entire wires from the nozzle head. From that moment it shifts layers at some point in the print. I tighten all screw, changed the belt and one of the Stepper motor. The offset hav got much smaller . Now is at 10 mm aproximatly. Last part, shifted layers after about 2 hours. Any ideeas about what is happening ?
