I decided to buy the FT-6 for my first printer and have mostly finished assembling it. So far it’s fairly complex and I’ve run into a couple of issues, but nothing I couldn’t handle. I think the hardest thing was getting the bed assembly to stop binding when it gets close to the bottom. The screw rods aren’t staying straight, which is causing the binding, so I’m looking for some slightly longer rods that are long enough to stay in the holes cut out for them in the top panels. Right now I’m just sticking the rods into some 8mm sockets to give them a little extra length. Somewhat ghetto, but it works!
