Re: [Emc-users] Aniliam Crusader II on YCM-18

I was preparing for a Crusader II conversion on my mill, then I bought a lathe with a Crusader M Lathe control that didn't work and converted that to EMC. The Anilam Crusader II and M that I have both use servo drives with + - 10V control and use tachometer feedback to the drive. The mill

Thanks to Jeff and all those who have made this possible. Even with my old obsolete Superior Electric drivers, I am now able to generate working configs from Stepconf. Interestingly, on my router I had to invert the step pulses on the X and Y axis but not on the Z axis to get them to move at all.

And I will add The original Sherline controller, and probably the current one utilize a microcontroller to read the step and direction signals without any external latching. This means that the direction signal must be valid long enough for the microcontroller to notice the step signal and
