In this video I assemble the push rods, effector, and auto level probe.
Push rods: They should be around 180MM and MUST be exactly the same length. If they are all a little bigger or smaller you can adjust in the software. Cut the head off of 12 M4X20 screws and screw the ball joint ends on to the rods, be careful not to split the rods so a tap may be needed.
