There seems to be a lot of confusion over what you need to use the Z-Probe, so I'm going to lay it out for you guys right now.
As it stands, the only way to enable the Z-Probe or change the probe routine settings is via https://easel.inventables.com/setup. Obviously this isn't ideal, and we'll be discussing this issue internally.
You need to have Easel Driver 0.2.7 or newer. https://easel.inventables.com/downloads
You need to have Grbl 1.0c or newer. Why? Grbl 1.0c has status message changes that we require in order to check if the probe is making contact or not (see
$10 setting). There are flashing guides all over, but I suggest you grab the version from the Inventables grbl fork since that will have some other defaults already set correctly. https://github.com/inventables/grbl
That shouldn't have happened. When going through the setup after setting your machine configuration, Easel will send the
$ settings. Then as you progress, each relevent
$ setting will be set. For example, on the homing page, clicking "Yes, enable homing" will send
$22=1 to the machine (assuming grbl 0.9+). Probe setup is the final step, so you could technically have gone straight to easel after getting stuck and been fine. Again, not having an abort button is a frustrating oversight, we'll be discussing it internally.
I hope that clears it up how to enable Z-Probe and what you need.
On a side note, the issue preventing some users from progressing through the probe setup should be fixed. If you still don't get contact on your probe please PM me and I'll help you ASAP.
