Ok, I have no motor lock, no step, no nothing. I have a 28 volt external supply, getting power to the Gecks just fine. I have + 5 volts coming from the PC power supply. I am trying Turbocnc for one, to dry run the motors. I have Tcnc set on active low. I show 5 volts from "signal ground" on my BOB to the 5 volt sig going to the Gecks. I have a Kelinginc stepper, wired up exactly as their diagram shows. Bipolar parallel. I have a good DB25 cable. I am recieving step and direction signals at the Gecks. When I do jog on Tcnc, the power light on the Geckos flickers. At first power up, the Led is bright, then I step once, it dims a little. Step once or twice more, it goes bright. What in the hell did I do wrong? I also have 33K resistors in place. Any ideas? No smoke, but the day aint over. HELP!![]()
