In my case though I already have a Mesa card (won at Cardinal raffle), 50 pin breakout panels and I installed solid state relays for spindle, coolant and brake when I converted the machine to Mach3/Gecko's. The machine also has a safe, hardware based E-stop circuit.
In theory all I need to do to upgrade to your AMP's is to figure out how to wire your PWM AMP's and existing encoders to the Mesa, configure the PWM Hostmot2 parameters and pass the machine's drive enable signal from the mill's E-Stop circuit back to EMC.
