I'm setting up an Ender 3 with the non-auto Clippy. I'm not great with G-code, and despite searching extensively, I haven't found any good examples of how to use it. Can anyone share some examples of how they've used it in their G-code?

So I've ordered a mk4 and it should be here soon, Im modifying my ender 3 to be a lot larger (500 x 500) so I figured I'd add 3d chameleon with the 3d clippy. So since I'm doing all of this I may as well upgrade the hot end and extruder. What hot end / extruder would you use for this set up?

No matter what I do this thing keeps sending either the left or right side filaments in together, causing a jam in the Y adapter, which causes the brass fitting to pop off inside of the fimalmet loader. I cant use this at all. I've taken it apart and I don't see anything that could be causing it. There is lack of any proper documentation so troubleshooting is mostly guess work. Hell I don't even know what extruder is considered T0. This has taken up way too much of my time all for one 2 color calibration cube that I was able to print, and that came out like garbage. Did I just throw away my money and time?
