ok so i think i will have to change the firmware with my vyper because i dont see nothing in cura for a tool change gcode in my settings, Also the bracket for the tube i dont have that same setup for my vyper,
No... you never need to change the firmware with the 3D Chameleon, we're do nothing with it. You can't use a previously created Vyper profile with Cura because they didn't define it with 4 extruders and they don't allow you to change the number of extruders. You can start with out Ender 3 profile and simply update the Tool Change GCode and Start and End Gcode, and it'll work just fine. You can also tweak the settings for your particular extruder by copying them from the actual Vyper profile.
Start with this profile, for example: https://1drv.ms/u/s!Av2Y103sCRZ3mtBbi1g1OXKWl2fLDQ
to make sure i understand i would have to use a printer that has 4 extruder units ?
You never need to modify your firmware (or electronics) to support the 3D Chameleon... that's a core part of our design. Cura has the tool change gcode in the Preferences|Configure Cura|Printers|Machine Settings... there are tabs for each of the extruders. See here:
As for the Vyper... which bracket do you need? The Anycubic Vyper is a standard Ender 3 clone and normally all our parts just work. Can you show me a picture of what you think the issue is? (There are several mounts available on Thingiverse and Tinkercad to tackle most printers... but if one is missing, we can add it.)
