Frustrated beyond limits!!

[widgitmaster]

I have set my Gecko & stepper & Breakout board up and wired them carefully, but no matter what motor I use, I can NOT get the steppers to spin in both directions!
The motor jogs smoothly, and I'm convinced its a Mach2 software setting!

Step is using pin 2 and active HI
Direction is using pin 3 and active LOW

Please help me!

Are you using Mach2 or Mach3? In the other thread, I said to increase the direction pulse width. In Mach2 it's called direction prechange. both are in the motor tuning.

Hi Gerry,

Using Mach2 software.
I tried changing that setting, it just made my motor start really fast then slow to current jog percentage of 50% it had no effect on the rotation direction.

If they really don't go in the opposite direction then I would suspect that your direction signal is not properly connected...or you're using the wrong pin.

need to set your outputs both to active low.

Changing the direction prechange shouldn't do that at all. What did you set it at?

[widgitmaster]

ViperTX: both Mach2 & the Bidirectional Breakout board are using the same pins.
-------------
PoppaBear10: I have set both outputs to Active LOW
-------------
Ger21: Your right, I was confused with the Acceleration & Velocity.
When I set the Direction Precharge to 3, the motor ran smooth in one direction, and vibrated without spinning in the other.

I noticed that CNC2PC.com has two boards:
a: Bidirectional Breakout Board
b: Parallel Port Interface Card

I have the Bidirectional Breakout Board, did I get the right one?

[ger21]

Just make sure it's set for pins 2-9 to be output.

Try increasing the direction prechange to 5,10,15,20,25 and see if it makes a difference.

The bidirectional board should work. Does it have a jumper to make it look like a plain parallel port?

No

Question,
Are the Step & Direction line Output only?
