Congrats/nice work. With no panels I had some ASA warping while printing my panel clips. Cardboard tapped onto the frame fixed that, but I'm still doing smaller part batches to play it safe.
I thought the wiring was pretty straightforward. I didn't find klipper setup that hard either. I've used putty before, but would still consider myself a novice in most things Linux. Beware that your first mainsail boot can take a little while. Also keep in mind that your access point name is case sensitive...
