Ender 6 BIQU H2 Direct Drive Gantry Mount / Fan Duct / BLTouch / ADXL345 / Filament Guide / Extruder Filler Kit by vampyrex13

Last crawled date: 2 years, 10 months ago

I wanted a clean and simple way to mount my BIQU H2 direct drive extruder that kept the stock blower fan, had the BLTouch close to the nozzle, and was compact.
This is a complete kit which also includes a filler plate for the original extruder location and a filament guide.
This mount is compatible with the shorter silicone bed leveling columns.

• (1) M3x16mm socket cap screw
ADXL345 Accelerometer
• (2) M3x8mm socket cap screws
• (2) M3 nuts

Versions
• There are two Ender 6 mounts; one with and one without the ADXL345 accelerometer mount.
• There are two Fan Ducts; one with built-in supports (inside mounting holes) and one without.
• There are two Extruder Fillers; one with built-in supports (under filler plate and inside mounting holes) and one without. If using the built in supports version, remove the bottom hole support first using a using a small screwdriver or hex key through the hole in the middle of the top hole support, then remove the top hole support.
Printing Notes
• Increase the number of walls to make the two towers the BIQU H2 mounts to stronger. I used 5 when I printed mine.
• Print the fan duct at .2 and use adaptive layers for the best success.
• The fan duct should be printed in ASA since it's sitting so close to the heat block. The other parts can be printed in ABS or PETG.
Installation Notes
• This is very precise and will be a tight fit pressing onto the gantry plate. If your print has a large elephant's foot, you may need to file the opening that slips over the two original heat sink mounts.
• The BIQU H2 mounts on the top and bottom, but there's also an additional hole to mount an optional M3x16mm socket cap screw from behind.
• Replace the two screws holding the hotend fan in place with (2) M3x18mm socket cap screws to attach the BLTouch mount.
• Made sure the BLTouch wires are are sitting flush in the mount and are not touching the fan.
• Wires are secured at the top right corner using two zip ties. Make sure none of the wires interfere with the limit switch.
• Re-use the stock bolts for the extruder filler
• Run your reverse Bowden tube through the filament guide to the PC4-M10 push fitting on the extruder filler.
