I have two problems, so I will break my questions into two posts. First, my printer and current settings:
Folger Tech Kossel 2020 kit build ((C) 2011 Marlin firmware from factory)
Simplify 3D slicer/printer software
Until yesterday, my delta printer was "dialed in" and printing whatever I threw at it. My bed is flat, auto-leveling was working like a charm. I have a part fan that is off for the first layer and set to 50% at layer 4. My bed is at 60 C and my hot end is at 210 C for the first layer and backs off to 200 C for all layers after that. I work in PLA.
Then, problem.
I found that suddenly all my endstops, leveling data changed. My bed used to measure out (X,Y,Z,0) at 1.1, 1.1, 1.1, 1.0. I am using a zero-offset magnetically attached mechanical switch to do the auto bed-leveling. I then measured the "new" bed level stats at 1.4, 1.4, 1.4,1.3, and the Z offset of the probe obviously moved.
As I re-leveled everything to find the new settings, they changed and finally settled to 1.2, 1.2, 1.2, 1.1.
Huh? Why did these all change, and why did they settle back down (most of the way)?
I updated my configuration.h file and kicked some prints off. This almost worked. If I have flat objects with large contact area-to-height ratios, the print will work. Things that have multiple, smaller contact points will not print, by about the 20th layer the print head will snag on something and pull it off the bed.
Any ideas, and thanks for looking!
