I manage to jog all axes, but only two at a time. I can jog x and y, but not z. Then I reboot my computer, shut down driver power supply, and I can jog y and z, but not x.
I have COMMON over usb port, 60V 15A PS, 3 1200 oz/in steppers. Controller is athlon xp 1900+ with 512 MB RAM.
I double checked ports and pins, and try warious combinations on output pins.
All three geckos are heatsinked on one big heatsink, and auto current reduction is enabled...
I dont use breakout board, pinned them directly from lpt port.
I did not connect ground from to any pin, could that couse the problem? Is usb 200ma to low for three geckos? What is the minimum miliamper value to run a gecko?
Any help is appreciated...
