For one thing, I have a delta (FLSUN) printer and have spent years getting everything right. Especially the first and subsequent layers. I’ve tried everything including glue etc. What worked and has never been a problem for over a year now, is that I got a caliper (used to gad spark plugs in cars etc.) and have adjusted the head to 0.1mm - At first, I tried 1.3mm and it worked to some degree but 0.1 is the sweet spot. Forget using a piece of paper. They aren’t precise and vary from spot to spot. Since I’ve adjusted the Z to 0.1mm, I have never used glue or other substances. Even .2mm layers stick perfectly and, I can remove the print even before the bed cools down with a razor blade. I do have a latice glass plate but should work with other plates. You might have to make slight adjustments, like using 0.13mm or more or less to get the ideal Z height. Never changes anything in the .cfg file.
The high amount of backlash has a mechaical root cause.
I got rid of it and installed ball screw spindles.
Pretty significant enhancement.
Still no perfect prints but I’m working on it…
I still have problems with my first layer. When I print 3 times in a row the same first layer test it will usually start too faar away and ruin the print. then I adjust Z offset live and command apply offset with a save_config afterwards.
Then it prints beutyful until next time then its far too close and squishy.
Adjusting offset again…
Any ideas?
Strange no?
What means this plane layer in fact that floats around a bit?
Sometimes its intersecting but sometimes far away from the mesh.
Maybe I have something here as a reason. Maybe some temp induced floating?
Also this Z value canges a little bit. Does anybody know the Klipper mechanism behind it?
Because I don’t understand why its not 5mm spot on as configured.
Where can I read about it? I didn’t find anything in the reference manual…
