Misaligned P.I.N.D.A. Probe
Misaligned PINDA probe is a very common issue that can be fixed by fine-tuning the build of the printer. There are several factors and adjustments to consider in order to fix it.
To fix it, you must consider PINDA probe position on multiple spots around the heated bed. However, once we get the first three right, then you should not experience any calibration errors at all.
Below you can find the description of the 3 main errors:
Side shift is not very common due to the built design. However, End-stop can be misplaced a little. In order to fix it, you must unscrew the End-stop and push it to its proper place - and while holding it, screw it again.
This can happen if you do not have the Frame perfectly perpendicular to the Front and the Rear of the printer. In order to fix it, simply unscrew the M12 bolts holding it and move the Frame to its designed position (either to the front or back, depending on the relative position of your PINDA probe).
Pay extra attention to the flatness of your Y-axis. We would recommend checking that all 4 corners are touching the ground as they did before this operation.
This is probably the most common shift of the Y-axis built you can experience. Just like in the Front shift, simply unscrew the M12 bolts holding it and move the Frame to its designed position.
Most of the time it will be a combination of two problems. Take your time with fine-tuning, as it is crucial to properly calibrate your printer.
