A PS of sorts: I'll get them automaticly from the unused stepgen4 pins But, I am useing this same card combo on a 4 axis 6040 mill, so I will need stepgen3 on that machine, but not 4. And that does have a vfd to control its 24k rpm spindle. > > (That is will the up/dowm PWM mode work?) No, that steers the pwm which modulates the bottom half of the bridge, and not externally separated, both sides on these full H bridge cards. The top half is switched from side to side by whichever dir line is true. That would tie up more pins the minute it leaves the 7i76 tb2/3 area. Because those are already complemented, I'll use the pwmgen.00 on p3 for axis A, and the pwmgen.01's pwm/dir on p2 5 & 6 for the spindle.
