I wanted to use my VZ-Hextrudort for my ERCF printhead but the filament is not entering the extruder smoothly. It has a flat surface instead of a chamfer where the filament enters and it gets stuck here. Also by hand it's hard to hit that hole. Is there anything I can do to ease it in?

The PTFE tube in the STEP file can be a nuisance when trying to model an extruder assembly around the Vz-Hextrudort and my CAD software is unable to remove the PTFE tube from the STEP file. Would it be possible to get a model without the PTFE tube attached? I get you're not wanting to share too much IP but struggled to work around the PTFE for my needs. As an aside I worked up a smaller Bowden adapter for it as well that might interest some...

-When printing with 0.4 Nozzle some features would benefit from being beefed up(here in Red)
Especially the main_body bottom right hole is having a hard time being sliced, even with thin walls active.
-Orange sections could be optimized to fit 2 perimeters inside by slightly thicken the model.
-I simplified the bottom right motor mount a little to optimize it for 3d printing. (in green)
-I also extruded the main_body lower right hole by 1mm to be able to fir a 16mm screw since they're more common.

-please update CAD to latest Version (doesn't match witch stl's

Is there any chance the multi-body CAD will be uploaded? Currently, it's a single, merged body, so working with it is a pain.

Thank you!

Hey Simon, loved how easy the Mellow Vz-Hextrudort CNC was to install and setup on a Trident with Dirtybird hotend.

Is there anything I should be looking to mitigate visible wood grain when printing Mihai's Inconsistent Extrusion Test? The Vz-Hextrudort surface finish is the smoothest of three extruders I have on hand (LGX Lite, and a SLS Sherpa Micro), but it's the only one with the wood grain visible.

I purchased two Vz-Hextrudorts with the included motor and both have the exact same finish.

Photo of the grain only difference between the two photos is microsteps 8 vs 32.
