Geeetech i3 Pro W Z axis wobble fix with homing

prusaprinters

<p>My previous design had an issue, where the homing could fail violently, because the carriage, which has the thing that triggers the endstop, would stop at the bed, while the wobble fix would continue to go down until it was tightly screwed against the coupler. The stiff springs I am now using didn't allow for enough movement of the bed and the Geeetech i3 goes a bit too much below 0 during homing.<br/> Now the wobble fix itself gets homed and therefore cannot move to far down anymore.</p> <p>Extra parts needed:<br/> M3 square nut (normal M3 nut might work good enough)<br/> M3 nut<br/> M3 30mm cap head screw<br/> M3 washer (optional)</p> <p>For the right side I am still using the old design. But the new one is also a bit beefier, so mirroring it for the other side might be a good idea.</p>
