Uconduit - Hot End Extruder Mount by RCC1

Last crawled date: 3 years ago

This is another alternative of an extruder mount for the U-conduit printer which uses a Metal J-head hot end. When I fabricated the Uconduit H-bot printer, I had some problems with extruder nozzle wobble. By spacing the X-axis rods farther apart, and using two linear bearings on the top 8 mm polished rod, I was able to keep the extruder nozzle side-to-side wobble a minimum.
To cool the extruder hot end cooling fins, a fan was mounted on the back between the two X-axis rods. This air blows through the extruder hot end mounting bracket from the back to the front. There is a short offset duct to get the air down a little to those heat exchanger fins on the front side.
The printed part cooling was accomplished by using a front mounted fan pointing down towards the extruder nozzle tip. Nut slots were used extensively to create the thread for the bolts (6-32 nuts) and the tubing fitting (10 mm nut).
