Firmware fail and port2 is noisy


Hello. Ive just bought a kit and have it constructed correctly, there are two issues to start with. Either stepper when connected to port 2 goes crazy with some noise and disregards the limit switch, ramming to the wall. Ive turned the current dial all the way down and can still hear the motor noise coming through.
I cannot get my plotter to work at all with any drawing, I have the panda .svg file loaded but when I press play nothing happens at all.
Also firmware upgrade fails every time. I have version 1.2.2… Is this all I need?

I need help
