Hi Folks
I am rebuilding my home built CNC machine and have now fitted a 1.5 kW spindle motor with a Huanyang Inverter.
My original BOB was a cheap chinese, 5 Axis version that came with a hand control and a small DRO which was fed from one of the group of three white headers on the board (see attachment) which, I believe, used the pulse information as used by the stepper drivers.
Unfortunately, this board only had a simple relay output for peripherals and I needed a new board with PWM output for the spindle. I now have such a board on order.
Does anyone familiar with my old BOB have any idea of the pin out connections for the 11 pin (4 axis display) header? What I am aiming for is to use the old display modified to the outputs on my new board.
I would also use the hand held 'jogger' too if possible which I believe just sends a simple pulse to the stepper drivers.
Any information would be helpful
Thanks in advance
