Has anyone got the cutter made yet? My servo will not be in until Thursday. Curious to know how it knows when to cut? Especially if it's a remote bowden setup.
As luck would have it, I think I got a good solution. With a few holes printed on each side, I found that I could use at least one of them to mount the cutter assembly to an "L" bracket and directly to the top of the guide rail linear block. The bracket is slotted, so I'm able to get the tubing lined up "perfectly" going into the extruder. This looks to be a good solution. If the servo would only get here sooner. 😉
I've got it printed, but my servo arrives Wednesday. I'm direct drive on a heavily modified Ender 3 v2 (XL400 extension), with a Micro Swiss NG, so trying to figure out how to mount it. I don't see much in terms of mounting instructions, so unsure how it should be mounted.
The cutting always happens before the 3DChameleon starts to unload the filament. You'll always back it out to the proper position, issue the switch command, which will immediately cut the filament, you can back out the filament the rest of the way with the extruder using GCode G0 E- commands. Once you've backed it all the way out of the extruder, you will then press the button which will tell the 3DChameleon to continue the color change by removing the filament for as long as you press the button.
Any chance we can look at the gcode that you used on the Ender3 v2 that you showed at RMRRF? Sorry, waiting on the parts gives me too much time to think about things. lol
I think Bill said in a post here that the Chameleon would detect the servo's presence and cut when it needs to without any other modifications. I printed the parts for the cutter and I am also waiting on my servo.
Yes, he did. But how? The printer's extruder unloads the filament before control is passed to the 3DC via the switch. So how does it know to cut it before that?

What is the expected orientation of the blade - tip on which side, or does it matter?
