Custom Integrated Compact Extruder for HevORT

[MirageC]

First Configuration of the HextrudORT released!

- STD/HT NOVA HOTEND ON MGN9

Visit the new HextrudORT web page for details: STLs, BOM, STEP, CAD and the list of planned configurations.
See BOM for assembly notes.





Hi Guys! Sorry for neglecting the forum lately...

I am putting this here for info and discussion. Will be back tomorrow
As posted on the other platforms:

Ouch! What a pain to design an extruder!
I mean a compact and integrated one.... Quite satisfied on how its turning out. It could be reused for HD, STD, HT. A version for V6 heatsink will be done.... if it works
Specs:
Motor: LDO Orbiter Motor
Gears: BMG extruder gears and shaft
Gear Ratio 5.5:1 (Aprox)
Bearings: MR95 Qty 2
Nova Hotend here shown

Nice! I like that.. Small/compact/functional.

Awesome!

My only suggestion would be to revise the design with the same 12mm diameter drive gears as the orbiter. The standard size BMG gears just don’t have a large enough contact patch to consistently push flow rates above 80 mm3/sec without stripping/slipping/grinding the filament. Using them for a speed optimized extruder is gonna cause headaches and create another bottleneck. I think the perfect design would basically just be a Hevort-focused fork of the Orbiter with a less aggressive gear ratio.

Cheers!

I'm working on the design with bigger gears. The problem with bigger gear is lower torque. We will need stronger motor or other gear to drive that setup.
For the same motor and 50 teeth plastic bmg gear, bigger 12mm gear only have about 68% the torque of the small gear setup.
