It is running! First print video: https://goo.gl/photos/iLR45rEwGqzyDJTW7 and https://goo.gl/photos/3y88xqDRfuDeizWD7 This test print is PLA at 60mm/s and I do not yet have the PLA cooling fan ducts designed/installed - working on that now - however the print result is as it should be considering no cooling. I went to my machine shop this morning and prepared a hexagon shaped 0.250 inch thick piece of MIC6 aluminum plate to be the base of the build platform. Checked it on my large granite slab and was pleased to find it was more than flat enough to suit me. Applied my Keenovo 120 volt, 900 watt heater to the underside and mounted it to the frame.
