Just in case anyone is interested I grabbed a shot with the macro lens still on the camera (lousy depth of field) and it's not the best picture. If someone wants I'll set up one with better lighting and depth of field that extends over the entire board. Anyway. The Bergerda drive I use for the spindle can take in 0-10V or step/dir. Since the MESA can't flip PWM and STEP/DIR on the same pins without reprogramming, for now I use the PWM so I can still run the spindle under MACH3 or LinuxCNC. I used a small far east PWM to 10V module but I needed a carrier board that brought the system enable out to the Bergerda along with step/dir and fault for the DB25 connector on the drive. The 0-10V goes to a separate connector on the side of the drive. Here's the photo. http://www.autoartisans.com/mill/SpindleControl/ServoPWMInterface.jpg And the schematic. http://www.autoartisans.com/mill/SpindleControl/PWMSpindle.pdf And the layout. http://www.autoartisans.com/mill/SpindleControl/PWMSpindlePCB.pdf The DB-25 matches the Bergerda which is configured for either 0-10V or for Step/Dir. One of the annoying things about the drive is that the DIR is different if it's 0-10V compared to the step pulses. The optos are high speed and that is then converted to differential. The notes on the top left corner describe the connector pins and the Parameter Numbers. These are the memory locations inside the drive that are set for operation. So PN4 sets the type of control of the motor. If anyone decides to buy one of these drives I had 4 PCBs made.
