Finished assembly, zero'd it, ran the break-in program, and wired up my torch to the controller. I had to see fire before I called it a night, so I fired it manually from FireControl and just jogged it across a piece of scrap steel at 100IMP.
I don't have any water in the bed yet, I'll do that this week when I move it to it's final spot.
The only gotchas I found in assembly were around places where there are multiple of the same things and the instructions aren't clear about which ones go where. For example with the lead screw bearing brackets, there's a short one, that goes on the X axis, and two longer ones that go on Y1 and Y2. Same with the stepper motor brackets. On the stepper motors, the one with the long cable goes on Y2. The bottom brackets are put on with self-tappers so you're going to have to get underneath it to screwgun all those in - if you have a way to lift the table might make it easier.
About 6 hours assembly if I had to guess by myself not rushing. I'd like to wire-manage a couple things but I'll do that after I get it into position. Running on a laptop with the laptop stand for now, don't know if that's the final config.
