Hello,
I made my prototype of 3D printer where I have same magnetic toolchange like you can see on the video here: https://www.youtube.com/watch?v=0ARCip5CrUk I tryied to generate config by RRF config tool ( https://configtool.reprapfirmware.org/Start ) but for toolchange it offers only XYZ position. To lock I have to go to position XYZ, but to grip tool I have to go more further = 5mm forwards in axis Y. Does anybody has same construction and can provide answer or "config.json" ?

@pawPrinter Nice work! I'll be inspiration for me. Could you please share your config file?
