Working with the new firmware on the MK3 - I see that the retract distance is fixed at ~10". I have been experimenting with a design to replace the Y adapter with a much smaller version that I want to integrate directly into the 3DClippy. This adapter only requires about 2-3" retraction after it is cut by the clippy (all 4 the same distance.) Since tip shaping is no longer required, the 1.8mm shape tube is not necessary, so a path with a little less tolerance (~2 to 2.2mm) seems to be fine. Is it possible to change this distance through any commands?

I would like to see this after you have it working. What printer are you trying to install this on?
I have a lot going on currently, but might get involved if you need help. I have been trying to get this figured out for a Rat Rig and need a version of the Clippy to make it work
I've never done anything with an Arduino before -- but I'll order an Uno and give it a try. Thanks for the help
Hi Ed, The Mk3.1 firmware supports that... it has a new Mode, Mode 3 that allows custom loading and unloading distances. To use it, put the 3DChameleon in Mode 3... then immediately after any command that moves a filament (or two), you press and hold the button for the duration of that particular move. Here's an example scenerio: To Switch from T0 to T2: Press and hold for 2 Pulses - Unit responds with nothing. Press and Hold For 20 Seconds - unit backs out filament T0 for 20 inches. Press and Hold For 21 Seconds - unit loads filament T2 for 21 inches. Each command that moves the filament has that secondary and optional third press that continuously moves the filament while the button is being pressed. Search our forum for Firmware Upgrade for instructions on how to install it if your unit doesn't already. (Mode 3 = press for 10 Pulses... it should respond with which mode it is in... cycles through 1, 2 and 3 for each 10 pulses.) I might add, this new mode also allows for n number of 3DChameleons to be chained together... because the distances are now variable, you can have as long of a chain that you want.
