Thanks got the catch on the max Z height - that was a typo. Was supposed to be 235. Yes, 'REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER' was the correct one. After wading through again, I discovered the multiple controllers and then that I had the wrong 'RepRap' one selected, so I got that working.
Then I decided to adjust the Z probe to where the nozzle was just touching the tape. After using some gluestick on the bed, it printed one of the better 1cm test cubes - it seemed to lay down the initial layer nicely after getting the skirt printed, but the cube had two anomalies - first, the base was a tough bigger than the rest of the cube, and the corners were raised.
I went back and made the '#define FIX_MOUNTED_PROBE' change you recommended, which changed it's behavior - on initiating Z-home, it then raised back up to 10 or 15mm, rather than sitting at 0, and I noticed that now, there is a Z offset option in the 'motion' menu that wasn't there before, set to 0.8. Only problem with that is if I enter it's option, say to lower it to 0.4 for example, it shows -5.0 in the menu, and I can only go further negative. I fear that will really try to drill through the bed. I then have to reset the controller to reset that.
When I tried to print another cube after changing that, it started extruding pretty close to a full mm off the bed, which obviously wasn't right.
Any suggestions there?
