The following tools are recommended for this guide:

A pair of cutters

1x Rat Rig V-Core 4.0 - Oozeguard Arm - Left (SKU: HW3730BC)

1x Rat Rig V-Core 4.0 - Oozeguard Arm - Right (SKU: HW3731BC)

Please note: The left and right Oozeguards are different. Use the provided image to correctly identify them

2x Rat Rig V-Core 4.0 - Oozeguard Silicone (SKU: HW3732GC)

4x Set Screw M3x8mm (SKU: HW3733SC)

Rat Rig V-Core 4.0 - Oozeguard Arm - Left

Rat Rig V-Core 4.0 - Oozeguard Silicone

Insert the Oozeguard Silicone into the arm as shown

Begin by pushing one end of the silicone "flange" through the Oozeguard Arm

Using a blunt object such as a flat-head screwdriver, push the remainder of the "flange" thought the Oozeguard Arm

Avoid using anything sharp as this can damage the silicone and take care not to bend the Oozeguard Arm

Make sure the Oozeguard Silicone is correctly oriented with the ribbed end facing away from the Oozeguard Arm

Repeat the previous step to assemble the other Ooozeguard

Left Oozeguard Assembly

Right Oozeguard Assembly

V-Core 4.0 X-Axis Gantry Assembly - Left Side

2x Set Screw M3x8mm

Slightly thread a Set Screw into each of the two marked heat inserts. Do not fully thread them in at this point

Left Oozeguard Assembly from step 4

Insert the Oozeguard Assembly into the slot on the underside of the X-Axis Gantry as shown

Tighten both M3x8 Set Screws to secure the Oozeguard Arm in place

Be careful not to overtighten the M3x8 Set Screws as you can force the heat inserts out of the printed part

Move the left toolhead over the Oozeguard. The silicone and arm should flex out of the way and allow the nozzle to sit firmly on the pad

If there is a gap between the silicone and the nozzle, first make sure that the Rapido hotend has the UHF adapter and nozzle installed. These are required on the V-Core 4.0

If the Rapido hotend does have the UHF adapter and nozzle installed, and there is still a gap, make sure the Oozeguard is firmly installed within the printed part

If the Oozeguard is too high and prevents the toolhead from moving to the end of the X-axis, adjust the Oozeguard downwards slightly by loosening the two Set Screws, lowering the Oozeguard, and then retightening the Set Screws

Repeat both the previous step, and this step to install the right-hand Oozeguard
