So I got it up and running, it actually works in both modes but in the “big tree” mode I don’t get a pop up. In marlin Mode it gives me the notification at the bottom of the screen. Clicking the dial indicator gets everything running.
The first time I installed the grey cables it would just freeze and not go into marlin Mode at all. (This is was the problem originally). Then what I realized is the cables are backwards. Idiot!. In the image the numbers 1 - 1 and 2 - 2 don’t indicate the two different cables which is how I originally read it at first glance. I noticed on the board it says exp1 and exp2 and I just matched those with the corresponding ports on the display. Then it all worked at which point I realized I was reading the instructions wrong. The image actually shows each end of the grey cable being 1 and the other 2. I could very well be the only one that read these instructions incorrectly but I suspect it’s what’s causing a lot of the issues that I was seeing.
This is how I thought it was presented when I first looked at it.
