1. Printed parts
Toolhead Mount
To install the Picobilical Toolhead PCB, you will need one mounting plate and two spacers.
The prepared STL toolhead_spacer_v02.stl contains the main body and the two spacers you will need. You want to print these in your frame or primary color.
The mount has a print support that you must remove before assembly.

Frame Mount
Print one frame_cover_plate.stl . This will make sure neither you nor the printer frame comes into unintentional contact with the solder joints on the frame PCB.
As with the toolhead parts, you want to print these in your frame or primary color.

2. Toolhead PCB assembly
Follow the manual, until ...
Follow the Voron manual until the PRINT HEAD section, and the steps where you mount the STRAIN RELIEF and spacers
Both of these parts will be replaced by the Picobilical Toolhead PCB and matching metal spacers.
You can find a list off all changes from the Voron manual on the Build Notes/FAQ V0.2 Kit wiki page.

Install metal standoffs
The two M3x10 BHCS was inserted in a earlier step in the manual.
Instead of using the 20 mm printed standoffs with heated inserts, use the two 16mm metal standoffs from the LDO kit.
Step Images

Partly attach PCB mount
Position the printed mount on the rear of the extruder stepper motor, aligned with the four mounting holes.
Attach the mount with two M3x8 BHCS screws.
The hole on top of the strain relief is for a heat set insert, however it's currently not used for anything.

Align toolhead PCB
Position the toolhead PCB in the mount. Use the V-groove at the top of the PCB for proper alignment.
Step Images

Properly attach PCB and mount
Fasten the PCB and mount to the toolhead using the two printed plastic spacers and two M3x12 BHCS screws.
The two plastic spacers will allow the screw heads to have a flat contact surface, even when the PCB is at an angle. Rotate the spacers if required while tightening.

Assembly complete
You have successfully completed the assembly and mounting of the LDO Picobilical Toolhead PCB.

3. Frame PCB assembly
Follow the manual, until ...
Follow the Voron manual until the ELECTRONICS AND WIRING section, and start here right after you have secured the MID PANEL .
In the later PANELS section of the manual you may skip the steps where you mount the CABLE PASSTHROUGH and MOTOR PANEL . Both of these parts are replaced by the Picobilical Frame PCB and cover.
You can find a list off all changes from the Voron manual on the Build Notes/FAQ V0.2 Kit wiki page.

Frame PCB Cover
Insert the printed PCB cover plate. The flat side should face upwards/towards the A/B drives. The middle cutout should face towards you.
Step Images

Frame PCB
Insert the PCB so it matches the frame shape.
Step Images

Screw it all together
Finish the installation with two M3x8 BHCS screws. These are screwed into heat set inserts you added to the A/B drives when assembling them.
Step Images

Assembly complete
You have successfully completed the assembly and mounting of the LDO Picobilical Toolhead PCB.

5. Additional Information
Reverse bowden path
When you install the reverse bowden tube, pass it through the slot in the Frame PCB.
Secure the filament tube with a zip-tie

Neopixels make it bling!
When you are ready to bling up your printer with some Neopixels, you can pass the wire from the Neopixel connectors on the Frame PCB to the inside of the printer through this cutout.

6. Extra parts?
Extra parts?
Some revisions of the LDO Picobilical Kit includes several fasteners that is not used in assembly of the kit. Keep them, you may need them some day!
