I've been tearing hair out in chunks trying to get my spindle control working. My 4 axis board uses all pins from db25 except #10-13,15. These pins are apparently all inputs. So I have been trying to get a pwm signal out of an input (pin 15) :what::banghead: I guess I'm out of outputs to use for this..... What are my options? I guess I could jumper the x and y enable pins together and use the other for output. Or I could set up an arduino modbus, or add another parallel port... But I don't have one on hand. Can I use a serial port? Any options I missed? Any suggestions?
Thanks.
