I just got my 3dc in the mail the other day and started to install. After getting everything routed the way i wanted, I started playing with swapping colors to get use to the way it works. Doing this by hand clicking the switch and running the filament in and out. I noticed that every time I do anything with #3 it moves color #2 in the opposite direction at the same time. I know that isn't right. See attached video. Do I have the 3dc assembled to tightly? after homing it does a little better but after running through 3 or 4 changes it starts having the problem again.
Any ideas?
setup: don't mind the mess as I tore it apart to try and fix the problem. I was originally going to run the Y-pipe directly on the extruder but I'm not sure it will work very well as it weighs more then expect. I was hoping to save time on color swaps with a shorter path. Any ideas on how to do this without having the ptfe tube between the Y-pipe and extruder bend super bad? But this is rather minor problem.
I had a similar problem when I first got the chameleon. I got around this problem by inserting ptfe tubes as far as they can go on both sides. I added shorter ptfe tubes with printed couplers on the inlet side so if I had to service it or help a filament feed properly it made it easier. I also added the screen and 3d clippy. The have the k1 speedy.
