Cant get past Calibrate XYZ without paper moving
Hi
I've been volunteered to print out some parts using a i3 MK3 3d printer which I didn't setup (I'm a newbie to 3d printing)
Its been OK printing for a while (occasionally would mess up during printing); but as of late we have something like 90% failure rate where parts get pulled off the sheet, or filament gunk builds up on the print head or on the part itself .
I read that the issue might be with levelling and to reset the 3D printer to defaults and re-setup (not sure if this was the best thing to do; but too late now)
I can't seem to get past the XYZ calibration.
On part 2 (at the right side of the bed), the paper always moves (doesn't scrape the bed but the paper moves around). I've tried to adjust the P.I.N.D.A. sensor but the paper still moves on Calibration step #2 ( https://help.prusa3d.com/article/xyz-calibration-mk3-mk3s-mk3s_112351)
Any one able to provide some direction for a newbie to help get past this.
Sincerely Paul

Aside:
- model actually is "i3 MK3S"
- firmware is 3.10.0-4481
- Using PETC Overture filament

We'll come back to this.

What is trapping the paper?
It it's the nozzle then moving the PINDA down by a thread should fix it. If it's the PINDA then it may be failing or it's connection may be loose...
To test the PINDA move the head away from the bed and look for the red LED to light up then move a piece of metal close to the PINDA and look for the LED to turn off.
Your original problem is almost certain to be either a dirty print sheet, a poorly adjusted first layer Z calibration or both. Once the printer is working run a first layer calibration and show us the resulting print *on the print sheet*.
Cheerio,
