Z Axis Anti-Rotation Packer for the Zonestar P802QR2

thingiverse

I'm using a custom Z Axis Anti-Rotation Packer\Wedge specifically designed for the Zonestar P802QR2. This clever solution tackles an issue with the stepper motor mounting tab, which causes the Z axis stepper motor to rotate away from perpendicular when tension is applied to the X axis drive belt. A huge thanks go out to "Mr John" for pointing this out! The Anti-Rotation Packer\Wedge is a simple bracket that fits between the Z axis stepper motor and the heat bed's transverse slide support, pushing the motor back into alignment. The packer is securely attached to the lower frame assembly using a sturdy M4 x 10mm bolt (refer to the fixing image). To ensure the part can withstand the forces involved, I've maintained a 20% infill and increased the perimeters to 3. It's essential to install this upgrade before tightening the X belt for optimal results, but it can also be easily retrofitted if needed. For added durability, I recommend swapping out the supplied cross-head bolts for higher-quality hex head ones.
