Any fix for the inconsistent z live adjustment issue?
Hello - I've seen a post here and there about people who continously had to adjust their z live adjustment after each print to achieve proper adhesion. I'm currently facing the same issue and was wondering if anyone had a fix - we're talking up to a millimeter of adjustment PER PRINT. I currently go to about -3 or -4 millimeters and then do a xyz calibration, but I don't really know how to actually fix it.

I have to make z adjustments of up to 0.1mm, particularly when changing the bed temperature, but never more. Are the belts tight? Are the heater, nozzle, and PINDA probe secure? Do you have the latest firmware? What materials are you printing?

Once the printer is well setup, you'll hardly have to change live z, if not when changing materials (but you'll be able to decide this by eye after 1-2 months of experience). For the first times, i recommend to use the V2calibration.gcode and a caliper to check width and height of printed line (i tend to be satisfied when height is 0.2mm).
If you get inconsistent results, you either have the bed not leveled or the pinda probe slightly loose (also check the upper nut, it must be perfectly seated).
BTW, i had experience with some broken models which caused slic3r to almost print in the air and i had to reduce live-z of exactly 0.5mm... so be sure to use good models when you're doing the checks. Also, update to the latest firmware (3.0.9 4 nov), there was a bug on live-z some time ago.
