Update:
V1.5.1 resolves the first-layer issue for most users affected by V1.5.0. If your first layer is still overly squished after updating, you can download a temporary 1.5.2 beta build for further testing.
We also recommend that you:
- Run
Multi-Toolhead Offset Calibrationagain with no filament loaded in any toolhead. - Before starting a print, make sure
Heated Bed Levelingis enabled so the printer performs bed leveling automatically before printing.
