Recently started using dual extrusion module after about 2-3 prints it wasn’t feeding anymore, took it apart and the only part with plastic still in it was the hot-end module, try to heat it up and push the plastic though but that didn’t work, anyone got any ideas of how to unblock it? [image]

this is what i do to fix it. cut the filament above the nozzle (right above where it identifies the nozzle NI0.4) and below the feeder lock. take out the hotend take your 1.5mm driver and loosen the set screw above the hotend nozzle disconnect the hotend nozzle wiring and grip the nozzle and pull.…

Heat it up to 250°C and push filament through. If this does not work it is possible to change the nozzle or clean it with a needle or something similar. There is a lot of information and possible tools if you search the www.

more then welcome… as an aside. the biggest reason i had for the right extruder clogging was the cooling properties of the module during dual color prints. does your module have the door with the expanded ports? if not you need the upgrade. the other thing is the pins behind the hotend. they are f…

Thank you so much, really appreciate the help. Will look into getting that other door for it.

I’m at my wits end. I have been attempting to use the dual extruder with no success in the past few weeks. I have the 2.0 A350 with enclosure installed. The dual extruder has the new faceplate installed, as well as a plastic component to keep the ill equipped levers from popping open. Over the past…

I need to print petg at about 15°C higher to prevent clogging. I used a tool change retraction of 12-15mm with a speed of 20mm/s. Normal print retract is 1mm at 30mm/sec, for me. What slicer do you use and what’s your settings? I searched a long time for possible solutions too and got to the end…

just thinking out loud here…first off you have something ive never seen before. a filament with two ground down sections. my experience says the first one is always enough. so that this appears to be starting a grind then stopping then grinding again is odd too me. the filament itself does look like…

Okay… tried to print pla at 220 degrees instead of 200. For the first attempt, it worked. I successfully printed 2 of the small items that I was attempting to print. However, I went for 3 of the little keychains I’m trying to print, only for it to fail again. Running 16mm nozzle switch retraction(35…

The two ground down sections is very curious, and definitely not a one off of my machine. I have gotten that result multiple times from printing these objects. I’ll be altering my standby temps next… I have them set to 175 at the moment which I thought was more than enough to keep heat creep from g…
