  21. Edit

    This is a good moment to install a base panel. I wired the Z-stepper motors (wire in the extrusion) after that I installed the base panel and the trims. I routed the stepper wires to the backside and tie ripped them temporarily to the electronic panel. This way I don't have to flip over the frame to install the wires to the Z-steppers later ion.

It would have been helpful if you had named and colored the parts as they are provided:

- 8x M3x18 Cap Head Screw

8x M6x20 Cap Head Screw

8x M3x12 Cap Head Screw

should have been black

- "Axial Thrust Bearing" is labeled as "Thrust bearing F8-16m" in the plastic bag

and in the step 1 image you don't show all the three parts

- "Rigid Lead Screw Coupler" is labeled as "Coupler Rigid Type BLK" in the plastic bag

- The orientation of the step motor is not shown until step 6, someone could not notice that and orient it the wrong way

Francesco Brasina - Reply

Had to go looking ahead for the motor position as well as it clearly shows the motor but not the connector...

Chris -

The trim part for the rear motor is upside down, or mirrored. Until it is fixed, you will need to mirror the part in order to use it.
