I did it with a Super Jolly. It’s relatively straightforward. The only minor challenges are drilling the chassis for the lower screws in the funnel and rewiring it with a jumper to bypass the doser full cut-out.
I used official parts (funnel from the ‘E’ version and de-clump screen) for simplicity sake but some people do a hack job with any funnel that fits. I used the Mini funnel for clearance for the dosing cup as the diameter was the same but I think the Major funnel is larger.
I also removed the PF fork and shaped a little condiment tray from Amazon into a rest for the dosing cup.
As I understand it the process is similar on the larger grinders too. I think @Cuprajake did a Major.
