I just swapped my toolhead for the Roto with the Duet Roto toolboard. I have. a BL Touch for main z probe and the SZP. When I run the SZP heightmap I always get the error "Warning: the height map has a substantial Z offset. Suggest use Z-probe to establish Z=0 datum, then re-probe the mesh." It seems like the whole map iss offset by about -.3mm or so. I set Z using the BLtouch and calibrated the SZP at z=2. Any ideas? I'm stuck.
