OHAI: Open Hardware Assembly Instructions

1 Before You Start

Each of the clear panels will have a protective cover on both sides of the acrylic.
This cover should be removed prior to assembly.
For ease of pictures, it has been left on for these instructions for better visualization.

WARNING: Do not overtighten screws that go through the acrylic!
Overtightening screws will result in the panels cracking.
Damage due to overtightening is not covered under warranty.

Remove protective film

2 Tools Required

-2.5mm hex wrench
-3mm hex wrench
-4mm hex wrench

Hex wrenches

3 Install Upper Brackets

Items required:
- 4x - M5 x 10mm BHCS
- 4x - M5 x 14mm SHCS
- 8x - M5 washers
- 4x - M5 Slide in T-nuts

Locate the 2 upper 3D printed brackets.
Using the 4 smaller button head cap screws, washers, and slide in t-nuts, start each corner of the bracket.

When installing the t-buts, be sure that you are orienting them with the flat surface in towards the top of the screw. If the t-nuts are installed with the flat side facing away from the head of the screw, they will not slide into the extrusion correctly.

Once the brackets are prepped, begin by removing the 2 outermost screws on each side of the top of the printer using a 3mm hex wrench.

Using the included longer 4x socket head cap screws, washers, and 4mm hex wrench, secure the 3D printed bracket into the top of the printer's frame.

Do not over tighten as you can strip the extrusion threads.

4 Install Side Panel

Items required:
- 4x M5 Roll in T-nuts
- 4x M5 x 10mm BHCS
- 4x M5 Washers
- 4x 3D Printed Side Panel mounts
- 1x ABS Side Panel

Take 4 of the roll in T-nuts and insert into the inside of the extrusion on the right side of the printer.
2 of the t-nuts will go somewhere near the top of the extrusion, and the other 2 t-nuts will go below the motor mounts.

Take the 4 m5 screws and put a washer onto each of them.

Take the 4 3D printed panel mounts and secure them to the printer using the 4 m5 screws previously prepared.

Orientate the mounts so the hooks face outwards and loosely secure to the frame. You should be able to slide them up and down with a little resistance.

Loosen the spool holder arm as well as the feed tube holder so you are able to move them up and down freely without them falling.

Take the black ABS side panel and set it close to the side of the printer and start aligning the side panel holders, spool arm, and feed tube holder until everything aligns properly and secure all 6 components.

Once secured, install the side panel by aligning the hooks with the side panel and slide down to secure in place.

Note: TAZ Workhorse printers will have the textured side facing out, TAZ Pro users with the Jetpack runout sensor installed will have the smooth side facing out.
