    Hi, I have been trying the Mach2 software on our drivers (with a cirquit converter) and it seems to work very well. The timing required is very low since the drivers are full step rather than microstep, but that is all we need at this time (6,000 steps/second but the pins need to stay high or low all the time between the steps). I'm including the port pin assigments for the MAXNC drivers. The most inportant feature nedded is the input on pin 10 that suspends the sequence of pulses from the software temporarily in case the motors are unable to keep up. This input needs to be sensed at every step with a timeout that will take into an error state (in case one motor is stalled). Let me know if this is possible.
The idea of a licensing agreement sounds fine.

PIN ASSIGNMENTS FOR THE 
MAXNC CL2 SOFTWARE

PRINTER PORT PIN ASSIGNMENT
 
1............... M3 OUTPUT (LOW=ON, PULSE FOR PWM)
2............... A AXIS (quadrature)
3............... A AXIS (quadrature)
4............... Y AXIS (quadrature)
5............... Y AXIS (quadrature)
6................X AXIS (quadrature)
7............... X AXIS (quadrature)
8............... Z AXIS (quadrature)
9............... Z AXIS (quadrature)
10.............. INPUT, MOVE ENABLE (LOW=NORMAL OPERATION, HIGH=STOP, SEE NOTE)
11.............. INACTIVE
12.............. INPUT, HOME SWITCH (NORMAL OPERATION LOW)
13.............. INPUT, G61 SWITCH SENSOR
14.............. M8 OUTPUT (LOW=ON) 
15.............. NONE
16.............. OUTPUT, DISABLE POWER TO MOTORS (LOW=NORMAL, HIGH=DISABLE)
17.............. OUTPUT, RESET CONTROLLER (LOW=RESET, HIGH=NORMAL)
18.............. ALL SIGNALS GROUND 
19 TO 25 ....... NONE


NOTE: MOVE ENABLE IS USED TO STOP THE COMPUTER STREAM OF CODES UNTIL THE SERVO
MOTORS CATCH UP. ON TIME-OUT IT WILL PRODUCE A SERVO ERROR.
