So success has been made. Started trying to figure out what was going on out of the 48 volt power supply I was only getting about 10 volts or so maybe 15 I forget. So I figured that the supply was the problem. removed the power supply went and grabbed a RD6018 I have and set it to 48 volts 7 amps as the original supply is speced to. Well as soon as I turned on the rd6018 it instantly pegged at 7 amps which is a problem. After some experimentation and tracing I found a wire that if I removed got rid of said 7a short. Turns out the y-axis stepper motor driver was bad. Removed it from the equation and everything works swapped x and y and y drive works so it's definitely the driver.

There was a spare stepper driver that came with it it's not shorted but it also does not appear to work.

Now that I have it somewhat functioning I need to see if I can either repair one of these stepper drivers or buy a different one. Spindle drive did work I didn't take it up very fast though.
