Great work with your MK3. I ordered a kit that arrived in late January, but due to major, unexpected changes to my schedule I didn't get the build completed until this week. Was happy to see that, after a couple of relatively minor tweaks (tightening a belt, adjusting height of the sensor on the extruder) I'm getting clean prints. Now my only issue is that I've managed to forget everything I learned about Fusion 360 over the past few months. So some major resharpening is in order there.
