I have a small module (DC_06) from Homann Designs for generating the 0V to 10V voltage for spindle VFD from step pulses that range from 0Hz to 25kHz for 0% to 100% respectively .
Under MACH3 it's easy to use because one just clicks on the Ports and Pins menu entry and up comes the dialog with this section. http://www.autoartisans.com/mill/SpindleStep_Dir.jpg With LinuxCNC it appears that there is only support (documented) for PWM to spindle speed. What do I set up in the HAL and INI files so that S3000 creates 25kHz stepping pulses (100%) for3000 RPM and one of the outputs is set high/low for M3/M4? Is the PWM module even required?
