thingiverse

This mod is designed specifically for Adimlab Grantry printers that utilize a single motor to move the Z axis leadscrew. This modification addresses potential tramming issues you might encounter with this printer, eliminating irregularities on the Z axis print (Z banding).

This is the only change you need to make (unless you have changed thread pitch). #define INVERT_Z_DIR true - You may need to increase the current to the Z motor slightly, as it works a little harder than before. - As with any modification to a printer, ensure thorough testing through the entire range of motion of the Z axis to guarantee smooth movement and avoid binding. - Depending on your electronics mounting configuration, you might require a longer Motor wire.
