hello all.

I've been searching around the web for an answer to a problem I have but I am not exactly sure if I am asking the right questions.

I have a fabricator mini. I really like it and its been an amazing little machine other than a couple of jams. My problem is that I am now having issues with my Z axis. The z axis will randomly change directions or even stall out. I thought maybe it was the wires or the motor but when I switch connectors with the x axis , it behaves the same way. I've tried reinstalling the software but no improvement.

I am currently thinking it needs a new board but was hoping that maybe someone here had an idea or even a direction I should be looking next to fix it.

thanks
