How to guide: Z motor replacement
If you have decided to replace your Z motor, here is a guide on how to replace it.
- 1.One side of the x-rods will be glued to the sliders, one side will not.Hold the slider in one hand, and the x-rack in the other.
- 1.While holding the slider and X Rack, gently pull apart from each other.Please be careful as to not bend the Z Rods, only a small gap is needed.
- 1.Rotate the slider so the pegs point upwards. The X Axis is now free from the sliders.
- 1.Take the print head and begin to slide it off the x-rack towards the end that is free toremove from rack.Set print head aside.
- 1.With printer on and connected, click the gear in the upper right hand corner to access settings
- 1.Navigate to the advanced settings tab and click the checkbox labeled "Expert Mode"​​
- 2.The spooler window should now open and you will want to raise the z height by 50 or so to get the gantries to at least the middle of the Z plane.
- 1.Unplug both USB and power cables from printer for next steps
- 2.Next, push down on a corner of the base and pull up on the same corner of the lid to remove the lid (see picture below for technique) Note: Take caution when pulling off lid. You do not want to pull the rods out from the base​
- 3.In order to gain access to the Z motor, you will need to remove the back right screw located underneath the print bed. You will need a T10 screw driver.
- 1.Once the screw is removed, you will be able to push apart the base and fluff at the corner exposing the Z motor.
​
​
- 1.Use needle nose pliers to grab the motor shaft to lift the Z motor from the motor cavity and remove.
​
​
- 1.The wire harness from the Z motor will be wound underneath another wire harness. To make sure the other wires are not disturbed when pulling out the connector, snip the Z motor wire harness indicated in red in the photo below and then pull the connector from the PCB.Warning: Make sure you are snipping the Z motor harness and not any of the other wires
- 1.Take the new Z motor and drop it into the motor cavity
- 1.Take the wire harness and use needle nose pliers to seat the connector back into the PCB.Note: Be extra careful seating the connector back into the PCB
- 1.Once fully connected, rotate the motor shaft of the Z motor to match the pulley's position above. Then take the top and bottom parts of the printer body and press them together to snap the printer body back into place
​
​
- 1.Screw in the back right screw to secure the bottom and top parts of the printer body
- 2.Take the top cube of the printer and align the rods into their respective holes. It may be easier to align one side of the printer at a time. Once aligned, press the cube top down until it snaps into place.
- 3.Once the cube top is back on, reverse the steps to put the print head back on.
- 4.With the printer plugged in, recalibrate the Z height before conducting a test print.
