Got my 3D Chameleon today and have spent the last 2 hours getting familiar with it...
I have one of those systems with an "enclosed base", and my Y axis homing switch in the back, so I have to get creative and design a 3dC switch mount that goes in the front, and fits in the gap under the bed (which means it has to lay flat, and to the side). That's no problem.
I have a BMG Direct Drive IDEX printer and am connecting the 3dC to E2. I plan to mount a spool system above and behind the printer to feed the 4 colors into the 3dC - hence why I reversed the motor mount and have the PTFE tube facing forward and down.
Is there any reason I can't and/or shouldn't shorten the PTFE tubes coming out of the 3dC motor assembly? What about the tube from the 3dC Y-adapter to the BMG extruder? I can make that really short so it doesn't flop around as shown in the picture.
Finally - if I completely screw this up and need to replace the PTFE tube - what are the specs on the tube so I can order replacement? I saw mention of 4mm compression fittings for inside the 3dC filament selector - would it be possible to get a link to replacement for those as well?
Thanks!
So are the length of the ptfe tubes the unit is shipped with can be modified without issue. Meaning it could be shortened, it would just need to be be long enough to reach from the placement of the stock extruder to the chameleon with enough slack to reach all parts of the x and z movement? Similair to a bowden tube needing to be about 14 inches for good range and decent loop.
