Reading came back consistently low, from 1.67 to 2.05. There is a regular 2d printer sitting next to it, but not in operation during calibration or any 3d printing. More importantly, I can't seem to replicate the issue anymore so, this may be unnecessary! I'll keep an eye on it and post again if that issue returns. Thanks for your help, gr5!

Ah, I see. So it does a separate active levering for each printcore, and the second one, for whatever reason, seems to be failing. That makes sense. I'll run that test and report back. Thanks!

Hi All, Just started working with a new print core, the AA 0.8, and I'll have an occasional issue where the Z height isn't calibrated correctly and the hot end will scrape across the face of the print bed after calibration and while the print is starting, plugging the filament into the core and scraping up the bed. This happens every time I attempt to do a dual extrusion print with with the AA 0.8 print core and only sometimes when printing with just the AA 0.8 core. I can't quite tell the rhyme or reason to what causes it. One file printed just fine, but when I reoriented the print by 90 degrees, it scraped across the bed. I'll attached a picture, just incase that's got any clues on it, as well as the gcode. Running Cura 5.6.0 and firmware 8.3.1. Any advice would be appreciated. Thanks! UMS5_Corrugated.ufp
