A Bowden Extruder mount for the Printerbot LC+ that mounts across both Z bars. Uses a quickfit attachment to allow easy access to extruder.
So what's a Bowden extruder? Well it's supposed to take all the weight out of the X-carriage so that the print head doesn't vibrate as much... Read quieter & more accurate. This is an experiment to see how true that is.
(Thanks TDEAGAN for the wonderful idea of running it across both z bars)
- PTFE Tubing, you'll have to pick a diameter depending upon the thickness of your filament. It should fit snugly. (I used a length of 20cm in current setup).
- Printed parts (ABS @0.7 infill) - 2 braces, one of everything else.
- 2x Pneumatic fittings (to fit ends of PTFE tubing)
- 9x 6-32 nuts (Sorry not metric, leftovers from building the Printrbot)
- 4x 6-32 bolts (25mm long)
- 4x 6-32 bolts (18mm long)
- 1x long bolt for the quickfit latch
Refer to exploded diagram for arrangemnt of parts.
bolt holes with the same shape go together, the rectangular holes should fit the nuts snugly.
Initially I've used TDEAGEN's hot end mount on the X-carridge. (http://www.thingiverse.com/thing:104005)
But, I'll be replacing that with something quickfit so that the entire assembly is easily swappable.
- After trying a Bowden extruder found that the plastic definately does ooze more from the Bowden. My initial research suggests that using 1.5mm filament instead of 3mm filament should solve this issue.
- Found that my print of the TGEADAN's X-carridge mount has some wobble, so I'm not seeing any accuracy improvements yet. I think the hotend is going to need a little redesign before I finish.
- There are too many loose wires on this thing, I'm going to have to try and move the wiring into the housing. (Current sketchup design has my first draft of the electrics housing).
