The mini does the leveling probe and seems to work well overall. What I’m seeing looks like the nozzle is too close to the bed, in some areas. Almost like the bed is warped. It’s more noticeable with small layer height. At 0.2mm I can see it if I look for it, at 0.1mm it’s bad enough that I cancel the print. Adjusting the Z offset doesn’t help, if I’m still too close in one area and too far in the other. I tested in Cura, including the beta, and simplify3d. It doesn’t appear to be a slicer issue. I also tried modifying the start script to heat the bed before leveling just to see if perhaps heat expansion was throwing off the probe. No change. I also manually cleaned up the nozzle and washers.
Obviously, 0.1mm is quite small. I only tried it as the designer of a part I wanted to try printing suggested it. But I would like to get higher resolution eventually. I have a 0.3mm nozzle on the way as well. From reading around it seems like the common causes are the bed actually being warped or the rods holding the X axis and extruder are flexing slightly. I thought I’d see if anyone has experienced either on a mini before I get out feeler gauges and such.
