Step 1

              Assembling aluminium extrusions               

• Align aluminium extrusions as seen in the picture. 2 x M8 socket cap screws for top corners of the X frame. Do not full tighten them yet. Just to keep the frame in shape. (Do not forget to insert the T-Nuts before tightening M8)
• 2 x T-Nuts for every corner.
• Black metal L brackets for each corner.
• 2 x M6 socket cap screws for each corner.
• Insert 2 x T-Nuts to the top extrusion as seen in the picture in order to be able to mount the spool holder later.
• Put your Z frame on a flat surface like glass or marble and then tighten the screws.

Step 2

              Mounting Z motor holders               

• Insert 2 T-Nuts in front and 2 T-Nuts in back. Position of the screws is not important at the moment. Slightly tighten with M6x14 screws just to keep them in place.
• Printed Z motor holders should be mounted directional. Smooth rod holes should be positioned on sides as seen in the picture.
• Insert 2 more T-nuts and mount 2 x Printed Z motor holders
• Align the Z motor holders with the extrusion ends and tighten the M6x14 socket cap screws.

Step 3

• Insert and seat the Z motors into the Z motor holders.
• Use 4 x M3x10 screws and 4 x M3 Washers to mount each motor in it’s place.
• Insert the blind L brackets to Z frame extrusions.
• Attach M8x40 screws but do not fully tighten them.
• While assembling multi point screw joints, it is better not to fully tighten any screws before others in order to ensure proper alignment. Tighten them in order like after slightly tightening M8 screws, tighten the L brackets and tighten the M8 screws again and final tighten the brackets after that.

With L brackets, there is no space to route the motor cables

Murathan Araz - Jul 2, 2018

If you are talking about the blind L brackets cables won’t go through that channel. If the L brackets that you mention is the ones at the corners under the feet, cables will go over the brackets. I will share some real pictures for cable managment instead of rendered ones.

The “misumi L brackets” between Z frame and Y beams. Looks like the original MK3 guide tells you to route the Z motors cables through the channel underneath the Z beams, around M8 bolt. In this build, I guess the only option is routing Z motor cables on the inside of the frame.

Yes, what I suggest is walk the cables through the extrusion channel at the bottom. Use the Zaribo extrusion channel plugs to keep them in place.
