Also looks neat but it is adding a bunch of wires again. I am actually looking at reducing the wiring and therefor reducing potential wiring problems.
I have since seriously looked at this Cartographer 3d, and yes it does have contact also. I might go for this to be honest, after all the wiring trouble I had with my machine I am now also getting peeved by that stupid magnetic clicky probe. It is taking forever to go pick it up, probe for QGL, dock it again, do another home, go pick it up again, do 25 probes on the bed, go dock it again and hey ho, we are ready to print!
I have seen the beacon just float accross the bed and ready. I am hoping this cartographer 3d, which comes with CAN as option as well, will do this as well and shorten the waiting times.
