Cannot set Z low enough

Just got a prusa mini and in calibration i cannot set the Z level low enough to print with my textured print sheet as it caps out at -2 so currently I can only print on the flat steel sheet. Is there any simple fix to this?

What Steve Smith meant is, slightly raise PINDA sensor 🙂
Don't pull it up too much, because you can damage coating on print sheet (about 0.5-1mm should be enough).

Mini+ with Bondtech upgrade & modified firmware...

Hi

Procedure  well explained in Prusa knowledge base https://help.prusa3d.com/en/guide/7-preflight-check_204705#204713

I did it on my MINI+ and 1st layer calibrations for both scooter PEI and textured plates went perfect
