Now that the belt tensioner arms are assembled and attached, it's time to start working on the frame. You'll start by assembling the left side of the machine as seen from the front:
|1||FDM-0001 (Front Left Leg)|
|1||FDM-0003 (Back Left Leg)|
|6||M5 T-slot nut|
|6||M5x10 machine screw|
|1||NEMA17 Stepper motor|
|1||GT2 Pulley (with grub screws)|
|6||M3x8 machine screw|
|1||Limit switch PCB|
|2||M5x25 machine screw|
|1||FDM-0007 (Frame Umbilical Mount)|
|1||FDM-0046 (Umbilical Swivel Part 1)|
|1||FDM-0047 (Umbilical Swivel Part 2)|
|1||M5x40 machine screw|
Front Left Legand insert the v-slot extrusions into the two square holes designed to take this part. Ensure that the extrusion comes to the end of the holes in which they're inserted. If you have a hard time getting the extrusion into the slots, gently slide them into place using some taps from a mallet.
Slide the GT2 Pulley onto the the motor shaft of a NEMA17 stepper motor with the set screw side facing the motor body. Align the pulley so that the end is roughly flush with the end of motor shaft, then tighten one of the set screws on the pulley into the flat side of the motor shaft. Tighten the second set screw as well.
Lastly, we'll assemble the umbilical swivel.
Swivel Part 1 and Swivel Part 2fit together as shown below, and are secured in place with a M5x40mm screw and an M5 nut. Tighten so there's no play in the fit, but the two parts can swivel easily. This part helps keep the X gantry umbilical suspended over the build area. Set it aside for now.
Continue to assembling the right side.
