Just a quick update for anyone following this saga... Last night I focused on the Panelolu2 issues and was able to pin down the problem to the 5V to 3.3 regulator. It looks like the kit came with the wrong part. It's supposed to be a LM340MP, but what I was sent in the kit and soldered down said "TJ" on one line and "3CMD2CE" on the next. Can't find anything on google to help identify this. It's the same package but it appears to be the wrong part and heats up instantly when I switch on the power (the +5V in must be shorting somehow when the power is switched on). The upstanding person who sold me the kit is standing behind their product and sending me the right part and I think it should be fine after a swap.
Dust, thanks for the idea on 230400. I'll give that a shot. it doesn't appear to be a standard option from the printrun pull-down menu, but it seemed to take it when I typed it in directly, so hopefully it will work. I'll try that out next and then start working on leveling the bed and calibration. Thanks for all the help from this forum. I couldn't have done it without this help!
