Ok, finally getting the maestro up and running, but keep having the connection lost error message.
Firmware is 1.0
Firmware version is 2.02beta1(RTOS)
Web interface version is 1.22.1
I am using ip address instead of http.

Tried moving ethernet cable to different router, different cable, but still the same error.
When I get it to to work, it is great. but when it doesnt work, well, it doesnt work. Any help?

I just tried it with the endstop as probe, mode 4, and that seems to have been the problem. Now I can move on to configuring everything else, and dialing it in. Thanks dc42 for your help!

@dc42 That was definitely not my intention at all.I am new to duet so, learning curve. I did change it to mode 4, using end stop as "probe" and am printing up a new endstop bracket now. Hopefully this will fix the problem. I have read that bltouch can be used on the maestro, is that correct? If so I will order one soon, and thenset it up for probing.

Trying to get my corexy with a maestro working. After heating the bed and hot end, web control homes, then asks me to adjust the bed. When I click on adjustment buttons, nothing happens. no movement at all. If I click on the ok butto, the pop up disappears, but then nothing else happens. I have gotten it to start a print a couple of times, but it always starts about 10mm away from the bed. I have tried manually homing, then starting print, nothing.
I even installed the latest web control and firmware bin files, still no go, although I do like the newer version of web control more than the old.

Here is my config file:
