I can't get any of the pinouts I have seen to work.

I need the correct parallel pinout for the attached board.

I got this 4 axis board here. I have seen multiple possible configurations for the parallel pinout, both on this website and on other sites. I am driving it in qbasic. I have written a test program moving it 100 steps. I can move 1 axis forwards, but not backwards. I am setting enable to high, then cycling the step pin (with and without the direction pin)

Another website has the following pinout:

X-Enable: PIN 4
X-Dir: PIN 1
X-Step: PIN 16
Y-Enable: PIN 17
Y-Dir: PIN 7
Y-Step: PIN 14
Z-Enable: PIN 5
Z-Dir: PIN 6
Z-Step: PIN 3

Note the THREE enable ports. Is this correct? Does each axis has a separate enable port?

Do I understand correctly that the enable pin needs to be low in order to drive that axis, because the one axis I have going was with enable set to high.

Please help...thank you.

Sorry to reply you late as I over-sight your post.
You may look at this 4-axis board for better understand. It is not the exact board but much similar

I used Mach3 to run the TB6560 board. You need to make sure "Enable" is active or it will not move

Thanks for the reply. I can't get that pinout to work either.

I am trying to directly control the motors with QBasic. Setting pin 1 on 890 high enables the board, but cycling the step pins with delay just makes the motors growl. (With or without DIR)

Is there s G-code interpreter that needs to be turned off in order for QBasic to drive the board?

I don't know too much about the QBasic as I used Mach3 to run it. You can get a demo copy from Mach3
BTW, I think the board is using "Active Low" (0V) logic to enable a port

I need to be able to control each individual step, when I need it. Mach 3 just doesn't have that level of control.

Does this board use a G-code interpreter?

Do you know who else might know how to use QBasic with this? Sainsmart support? Any other ideas or contacts? Thanks again.
