My MPCNC is coming together nicely…just dropped the middle assembly onto the rails and put the steppers on. Time for the electronics. A few things have popped up so I thought I’d ask.
when I slid the Z assembly into place the leadscrew didn’t want to thread into the brass nut (which is at the bottom of the assembly - might as well check that that is correct too). I removed the nut, drooped the leadscrew down, threaded the nut on the end and slid it all back up. Now with the nut resecured in place the leadscrew is HARD to turn. I suspect something isn’t aligned but not sure what to check / adjust.
The boards - should they be enclosed in something to keep them out of dust and accidental harm?
