Hello *, I have developed and build a non-invasive dual Motor extruder. [image] On the rendered Image some parts are hidden, however, I did build it, and it did pass the first tests. But I currently have a problem with my filament load and unload scripts. For helping you with helping me, I wil…

The maximum time has been used on trying a software solution, so I solved it with solution 3. hw step/dir/enable bridge. The second motor is still declared as [extruder_stepper extruder_sync] just for the case Klipper is doing some inits on the driver while enable the stepper. But i no longer care …

Looks good. What are the advantages of having two extruder motors? I’m guessing they’re too massive for a direct drive - is this correct?

[image] mykepredko: they’re too massive for a direct drive This is my guess too. Good for a bowden setup.

This dual Motor extruder has 3 advantages: There are no invasive gears which are damaging the filament, instead there is are 2 gt2 timing belts that grabs the filament carefully over a large area If 1 motor is used there is need for a gear which would introduce backlash (if common dual drive extru…

I knew I saw something similar: [This experimental extruder is a TPU beast!]

Hello @EddyMI3D , I watched the entire video. Yep. Good show. I like how the fellow put together the parts w/ the ideas he had. That is neat. Seth

Ok, this kinda other usecase (direct extruder agains bowden extruder). Additionally, the extruder here addresses some problems that the extruder in the video does not address. The dual motor extruder has a mechanism that allows to control the pressure on the filament The dual motor extruder absol…

Really a nice design. :+1: Personally, I would never exchange a direct extruder for a bowden one. IMO, the design inherent drawbacks (in fact the bowden itself) just cannot be overcome, regardless how good the extruder is.

[image] masterq: Maybe I found something for the requested solution here: Reddit - The heart of the internet It is still a hack, but I’m fine with it if it works. I will post a config if it works! Sadly this will not work, so I have still no solution :confused: [image] I run into this is…

[image] masterq: Thanks for this, I’m already working on my own fork so merging it with another could be annoying ^^ Can you maybe start a pull request for this, so it comes into the master? I already tried with my features, but it was rejected. I think you have better change with M302 as this i…
