Micro swiss direct drive Ender 3 pro with 3d Chameleon 4 color

This looks like a really good solution. I had wondered about the Micro Swiss DD setup with the 3DC but this seems to be the part that it was missing. One thing I'm curious about - since DD setups are sensitive to vibrations which can result in ringing or other artifacts on the prints, have you noticed anything like that with the extra weight on the extruder?

No, there is really no extra weight but really more drag on it. The weight is normally (and ideally) carried by the PTFE tubes and the top mount. Drag can cause a rotation to a bad fitting extruder, but in my experience, it doesn't show on any printer.

Excellent! So with the part William made and that particular setup you can have the feeder bowden tubes any length? I'm trying to visualize how I would want to set it all up in my enclosure and am envisioning mounting the steppers to the ceiling of the enclosure rather than the frame since the spools are fed from above. But in doing that it would mean the tubes from the steppers to the junction would be 4-6" above the top frame. Would that be a problem?

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.

@mindseye3 You need to reduce the tension on the drive to the point that it will grab and load. If you tighten it down too tight, it will apply way too much force to the filament. Also, make sure the extruder motor is running as the filament reaches it... and not after... both motors need to be running at the same time for it to load properly.

Do you have any gcode samples for cure that move the extruder and filament loader simultaneously? I'm struggling with how to get this combination working
