Powered up system for first time. All 5 volt power from transformer and usb working fine. Hooked up drives as per instructions regarding setting com to 5 volts on a C1 board from CNC4PC. Tested drives with self test and they work. My home and limit signals work, as the leds go on and off when I activate these switches. I get no power (leds do not light ever) from my outputs. I am using Mach3 software and have verified my parallel port. I have the X,Y and Z enabled and on low active, but I get nothing when I try to tune the motors. When I power up the system I get a thump on each motor, like locking into place. Can anybody offer any help?
Try switching from low active to normal.
