@1st_Kiwi_Nomad Loved your scientific explanation. Have to admit I had to read it twice but I got it!. Beautifully said. Yes, it’s also a deal breaker for me if not hackable to the Classic Nomad. Mine is already “hacked” to use the Triquetra probe and it works great. The problem with the Triquetra is that it needs Universal GCode Sender to work and I’d love to use Carbide Motion because of it’s tool length probing. Right now I can’t use the Triquetra with Carbide Motion because it won’t use some GCode needed by the Triquetra.
