Try to tick "invert" checkbox on X,Y and Z step output pins. Maybe I should be a little clearer on this. Recent versions of stepconf uses double-frequency stepping. The default setting in Stepconf leaves the step pins for L297 in the wrong idle state. When a DIR change is issued the L297 will lock up. Inverting the step pins fixes this.
May I suggest this default is changed in Stepconf?

I'd like to try out the alternatives before putting out the money for Mach3 so I'm in the process of installing EMC. I've run the latency test, loaded I'm getting around 14200 unloaded about 8000-9000ish. Everything looks good there. When I run the stepconf wizard I allow the system to decide the step settings for the L297 configurations. When I get to the "test this axis" step, nothing moves. I can watch the lights flash on my BOB, but no information seems to get to the Steppers. I don't know who makes the steppers on this machine or what their specs are so I'm kind of in the dark here. I'm assuming that I have an issue with the step length setting, but where do I go to diagnose exactly what I need to plug in here? Do I just want to shot gun it? Take a wild guess and start increasing the numbers until they work? I can also activate the limit switches, hit E-Stop, turn the spindle on and off, etc from within Mach3 so I know I'm getting communication.. just no Stepper movement. Any assistance would be appreciated. - Michael Jones ---------------------------------------------------------------------------- -- This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
