Basic Information: Printer Model: Neptune 4 Max MCU / Printerboard: Manta M8P V2.0 Host / SBC: Mainsail klippy.log Unable to acces Mainsail ATM Hello, i have an idea for my dual extruder setup to make it really compact. But i want to know first that it is really possible to configure in kli…

I had a printer that had a hot end that did basically what you’re proposing - the Zortrax Inventure. One stepper was used for extruding on each of the two nozzles while the other was used for moving one nozzle up and down as well as selecting the gear path for the extruder. When it worked, it was …

but after about 1,000 hours it became a nightmare with the dual path extruder ended up having the filament getting wrapped around it personally i dont see how this can happen when you contain your filament in PETF tubes as much as possible and make the entire system as strong and closed of as pos…

In the Inventure, there were no PTFE tubes in the hot end. They were used to bring the filament to the mechanical pieces of the toolhead which were largely brass. The overall printer mechanism was very complex - as originally designed, the filament was stored in cassettes from which the filament w…

[image] mykepredko: having more PTFE tube would NOT have improved the situation. Longer PTFE tube causes more friction. I’m not surprised.

I think @Jasper was asking about inside the toolhead and that’s the question I’m answering.

Please don’t get me wrong Myke. I was just commenting, but my thoughts were on the extruder from @Jasper . What do you think about my last edit above?

I think this is your last edit from above: [image] hcet14: Are you positive to keep good tension to move the filament exactly? Your lower drawing (showing the moving tension wheels coming down to be in contact with the stationary one) is how I envisioned things and why I’m talking about the …

You got me.

I didn’t even thought about that problem
