After upgrading to 2.5, printer can‘t find calibration point
Hello,
After upgrading to 2.5, printer can‘t find calibration point.
My story:
After upgrading to 2.5, printer can‘t find calibration point. Sometimes it can’t find first point, sometimes third point, but mostly it can’t find point number 4. Couple months ago when I upgraded my printer, I have tried 20-30 times to calibrate it.. but nothing happens, always comes messages that he can’t find calibration point. Then next day in the morning he found all the points. I was happy. Yesterday I wanted to print some stuff and I see that the nozzle is 2-3 mm above the bed makes the first layer. I calibrated the high with live z ( more then one 1000) and it worked well. After I though maybe I should make new xyz calibration, and now the same problem can‘t find calibration points. And always different, sometimes 1 point or 3 point or 4 point. I have tried to put PINDA up and down, but nothing happens. Maybe the PINDA or the bed it self has some hardware problems and I need to change it?

sounds a bit like the problem I had

During the first calibration he couldn't find the second calibration point.
Try again without the steel sheet.
Move the nozzle by hand down until it nearly touches the build plate, take a zip tie but use the thinner front end to set the distance for PINDA.
afterwards follow the wizzard for setup.
In my case it helped with the calibration point as well with the head crash.
wish you luck.
