Having "messed with" both the gantry component and thanks for writing that and JA now Master. I much prefer JA homing. Much more straight forward to me.
A couple of vids showing my testing of JA https://www.youtube.com/watch?v=1OtWNuLWfwc https://www.youtube.com/watch?v=wgNLd6A34Vo JT On 8/25/2016 12:18 PM, Charles Steinkuehler wrote: > On 8/25/2016 11:38 AM, dan...@austin.rr.com wrote: >> So I guess it does do that.
