I’m Printing calibration pieces now to test it. Its so hit and miss that i know it has to be something mechanical. Like something binds. or shakes it off course. I print at a different area of my print bed each time. not always center. Which speed settings are you asking about? there are several ones for infill and perimeters and such. Let me know which details you need and I will get them to you. On this model the first one printer beautifully. The second and third both shifted at 7MM up each. Printing a XY Resonance test first to see if i can get out the echos (or if they show up in it) and next a Z resonance test.
*EDIT It has done this on 3 different models now. So not a bad file.
