No Door text.
I test boards for Carbie3D so I have upgraded 3 times now, so I'm a little more familiar with the process (and errors) them most. As soon as I saw the Z move down (rather than up) I hit my estop, reconnected and went into settings, clicked on the log window (saw that Shapeoko 3 was selected), then I opened the MDI page, typed $$ and looked at the settings in the log window (mainly I was looking for $130-132 (machine size) and noticed that the machine TYPE didn't take.
Went back into settings, reselected Shapeoko 3, and clicked Send. Typed $$ back at the MDI page, checked the setting, and saw that the setting were NOW correct.
THEN I clicked home machine, and it all works great, and have used the machine nearly everyday since then (3/22).
The signs you are posting clearly tell me that the wrong machine is inside GRBL, and it is easy to change. Now why didn't it take the first time? I don't know.
