I have big problems getting my first layer dialed in properly when it is covering the whole plate. I have a QIDI Q1 Pro and did a proper platform calibration right before this print until SCREWS_TILT_CALCULATE showed me that I should not adjust any of the points anymore. Then I started this print of a single layer with PLA at 0.20mm and a .4 nozzle. I used the controls to fine-tune the z offset when it started printing (in the lower left corner of the picture). I use filament from dasfilament.de. Bed temperature is 60°C and the printing temperature is 220° at the first layer, which works fine with this filament when the print is only in the middle section of the bed. Print speed and retraction are at standard and should not matter for this problem.
I do not understand how single islands on this print can be so bad when right around them the z offset and bed leveling are ok.
I'm a bit desperate now and would be happy about any help or hints. Thank you!
