I am attempting to install Clippy on an Ender Max so a little prelimanary explanation before the question may be helpful. I am printing the Ender V2 version to get a better understanding and to see how that will fit on the Max but I am thinking it will have to be a hybrid of the SV06 and the V2. The X carriage mount holds the hot end assembly much lower in relation to the topside of the mount. In the video for the SV06 it looks like a Max version would have to bolt differently on the Max. The V2 clippy can lay flat closer to the top of the hotend housing. I think it's best with clippy closer to the top of the hotend so less has to be purged.
Here's the question: When you don't use the machines extruder do you just retract 10 mm then cut? Would you pull the filament back ten m

I thought it was easier with Clippy and not having to do the shaping. I haven't printed yet but I had it moving and changing. I'll try as you suggest. Where is the K1 code?
