having a hard time with first layer calibration, and PINDA
I've read many posts about first layer problems, and pinda placement, I'm running into the same issues. When I use a flashlight and watch my nozzel extrude during print, there's no "squish", it's just laying out a line, and it never sticks to the bed. I cranked the live z to nearly -1.435 at one point, and still had some issues with that first layer being a bead of plastic instead of a layer of plastic, as the print head moved over the surface it would drag the corners, so I knew something wasn't right.
After reading many posts, I'm assuming my PINDA isn't set right. My PINDA also doesn't look like anyone elses, it's just got some glue on the top above the spring and I sometimes see a light in it. Honestly, I hardly know what the PINDA does. Anyway, I've tried multiple heights for the PINDA. I follow the manual, home the printhead, take it to center, put the sensor on the center of a ziptie and tighten it down, then I go through wizard calibration (I'm not even sure I need to do that). I've seen some PINDA calibration prints, but I can't print anything to apply that technique.
Each time I can't get first layer adhesion. I have the steel sheet bed. I've been trying to just print the included batman logo, and every single print has failed.
So here are my questions:
I appreciate anyone's time and help in this.

Ok, I missed this note in the manual..
The aim is to lower the nozzle until the extruded plastic sticks nicely to the bed and you can see it is being
slightly squished. The value set should not exceed -1 mm. If you have to adjust it more, move the probe slightly higher.
So that answers my greater than .1mm question.. raise the probe more.
Also - it looks like XYZ calibration is needed after moving the PINDA. Is this correct?

That is correct! If you move pinda do a calibration.
Do not move the PINDA to much! If it is to high, the nozzle will dig into your bed! So take your time and do it like it is recommended in chapter 9 of the build manual

Thank you! Good to have validation. When things are failing and you just don't know what to look at, it helps to have a definate answer to turn to for a specific problem.
