First layer calibration help
Hello all, I watched the first layer videos and understand the concepts. But I think I need some mechanical adjustment to help the live Z changes in software. I calibrated the PINDA like in the guide and run the openeing calibration and the paper does not move. Then I run the z adjustment calibration, and I can not get the nozzle close enough to the sheet ( I was at like -3), so I am guessing I need to adjust the PINDA sensor again to help get the nozzle closer to start with.
When doing the original PINDA adjust the first time the paper moved, so I moved the PINDA down and it looked like in the guide pic, and the paper no longer moved. I am guessing I need to move the PINDA up some to get the nozzle closer to the heat bed in that calibration, I have feeling when I do that the paper may move, since that's what happened prior to moving it down. Can I ignore the paper slightly moving? Is the correct set of adjustments to make to get a better starting point on the nozzle and hopefully not hit over a -2 on live z?

It wont let me edit the post for some reason now, but the secondary question I have to this is the PINDA sensor, when it was too high and the paper moved, I had to move the sensor down. Did this increase the accuracy of the sensor so then it found the right spot or is there a correlation with PINDA height and nozzle height (PINDA up -> nozzle down, PINDA down -> nozzle up)? I guess if its the first I shouldn't mess with the PINDA since it is not hitting the bed with the nozzle at this point and passes. And I am not sure how to fix my live Z adjust to get the nozzle down to the bed.

The lower the PINDA, the higher the nozzle, and visa versa, is how it works. It sounds like you need to raise the PINDA a little so it is just above the tip of the nozzle if you are having to adjust the Live Z that much.

Perfect, that's the info I needed, I didn't want to keep adjusting over and over without the correlation. I will redo the PINDA again, thanks.
