I'm a noob, so I hope the solution will prove to be simple ...
I have done all the trouble shooting I can think of and still have no motion. The motors power up, I can't turn them by hand, but nothing happens when I try to move the motors in the tuning mode or with the on screen jogging.
My set up:
XP SP3 Laptop with a MosChip based card
Mach 3 2.0.047
CNC4PC BOB
Gecko 251
36V powersupply
Keling 285oz/in bipolar motors
Mach 3 Settings
Going to the Hardware Manager, The LPT(3) resources gives me two sets of values:
FEE8-FEEF
FEE0-FEE7
I have used both FEE8 and FEE0 in the Mach settings, but no love. Otherwise the port settings screen has only Port 1 enable checked, nothing else is checked, and I have left the speed at the default 25K.
Motor Out
X, Y, Z are enabled using pins 2/3, 4/5, and 6/7 Port 1. Active low settings are turned off.
Tuning
On my X and Y axis, they are set to drive a 0.752" diameter pulley reduced 3:1. The 251 cards are 10X micro stepping cards. The math is a little complicated, but I end up with 2539.7 steps per inch. So far I have used that value as well as just using the default 2000 steps per inch.
On my Z axis I have 1/4-20 thread screw. 2000 microsteps per revolution x 20 revolutions per inch gives me 40,000 steps per inch.
I get NO MOTION AT ALL. I don't know what else to check. The diagnostic page looks normal, EXCEPT that I have a RED at Enable 1. I don't know what "Enable 1" is, and I notice that in the set up videos Art's screen shows no red for any of the outputs.
I don't know what else to test.
Any help is appreciated.
