If you like to install a heated bed on your da Vinci mini w, you need to lift the Z-axis limit switch, otherwise your nozzle crashes right into your printing bed while homing all axes. To prevent this I designed and printed a raiserblock with 12mm height which fits the dowel holes of the mounting plate and the dowel pins of the switch. To mount the switch, you need 2 longer M3 scews or 2 pieces of M3 allthread with nuts. For other heights I uploaded raiser blocks from 3 to 12mm in 1mm increments.
Have fun and print warping-free ;-)
