Hello Bill, Did you ever post a video of the cutter set up and function?

So at risk of sounding totally ridiculous, what do you use to actually turn the POTs?

Perfect. I will cut and paste it. Thanks.

Verified 1.8mm tube installed. Tubes are not deformed, flared slightly and fully inserted into Y adapter. I cut them with a tube cutter to make sure they were square and clean cuts. I will zip and email you the pictures as they will not load in this reply.

Removed Capricorn filament tube between Swiss hot end and gears, replaced with your provided PTFE tube. Helped a little bit but still not getting retraction of the filament much beyond end of PTFE tube before binding (at the spool end of the chameleon Y, entering PTFE tube).

How do I adjust how far the 3D Chameleon drives are feeding the filaments to the extruder gears? It keeps coming up shy of the gears.

How did we get the filament to engage the extruder gears with this set up? The pressure on the gears requires the lever to be pushed upon the filament load.

I am experiencing this problem of the tubes being too tight as well. Just as an additional note, I have the 8 line system and both sets of tubes are too tight.
