LDO Picobilical

The Picobilical by LDO is a PCB mod designed specifically for the Voron0 series printers. The Picobilical is based on V0-Umbilical by timmit99 and retains its original advantages while introducing new features.

Toolhead Mount

Step 1 of 2 in this section

To install the Picobilical Toolhead PCB, you will need one mounting plate and two spacers.

Frame Mount

Step 2 of 2 in this section

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

1

Follow the manual, until ...

Step 1 of 6 in this section

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

Step 2 of 6 in this section

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.

Properly attach PCB and mount

Step 5 of 6 in this section

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.

Follow the manual, until ...

Step 1 of 5 in this section

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.
