The motors haven't been attached to the machine throughout the tests.
I attached some old motors to the driver board and they worked fine, unfortunately they aren't powerful enough to move the machine.
The motors I have are
these ones
The Driver board I have is
this one
I am supplying the board with
13.8v & 7amps, I know thats very low but its the best powersupply I could afford and find that was UK wired.
I have the motors wired in series, I have sat for hours with 1 motor and tried a lot of different settings on Mach 3.
I'm pretty much an amature at this, how would I check the ground connections?
Thank you all for your replies, its greatly appreciated.
