Hi everyone, I've recently upgraded my Makerfarm 10" i3V with lead screws and it's been a struggle to get it working properly.

I purchased some of the parts separately from Makerfarm and the leadscrew from Amazon.

The instructions from maker farm had me change the z steps from 4000 to 800 but I'm not sure if that's correct. When I tell the printer to autohome the Z motors move ungodly slow.
I'm basically experiencing the same problem as this Youtube video: https://www.youtube.com/watch?v=6c3Eh-fIInA

Thanks!
