Late last night I plugged everything in and pressed that power button in back… and the Sumpod came on, and better yet, no smoke! Just have to load the firmware…but that is ready to go.
One complication in the wiring (which will be in the forthcoming documentation ) is that the LAN cable meant to wire the LCD just didn’t work. The problem is that most LAN cables are meant for insulation displacement connectors, and not soldered. Mine would not take up any solder, almost like trying to solder aluminum. The stranded wire is silver in color but believe me, it will not solder! So, being economical, I just made up a replacement wiring harness from left over stepper motor wires. I knew those would come in handy!
