I've made the beginnings of a drag knife TC tool. Curious if anyone else has done this. FAQ: How does it work? I dunno. I just have the hardware made right now. Does it replace a 3d printing head? No. It has no connections so I figured I would just send the command to lock while holding it. Why? Because. STLs? Maybe if it works I'll post them. What software? SheetCam (maybe) - not sure what machine to pick in that for Duet. What knife? "EVISWIY Silhouette Blade CB09 Graphtec Holder with Vinyl Fabric Cutting Blades (30/45/60 Degree)" - a whole $16 How will you implement it? Maybe have a macro that I call to prepare the machine for drag knife mode? You don't know what you are doing do you? NOPE.
