Hey guys I'm a newbie using the newest version of Linux cnc my problem comes when trying to do the stepper configuration and the pinout for the db25 connector. The company only sent me a lousy set of directions for mach3. I'm attaching a link of the board. http://omc-stepperonline.kancart.com/item_detail/197#!detail. any help would be great.

Can you post a picture of the driver board?

Attachment 313088 I'm hoping this picture uploads but this is the board

Ok, that looks like the typical china breakout board, (BOB)
We did some testing on these, and they seem ok, try this PDF manual from our site

I should also have a Mach3 XML setup file kicking around somewhere, but the board is very straight forward, if you have any questions just post them

[rockcliff]

Here is a Mach3 XML file for that board, just remember it's not going to be specific for every setting for your exact setup, but it will get you close, you will still need to adjust things like motor tuning, etc,



With the latest Ver. of LinuxCNC You can "import" this Mach3 XML file to setup LinuxCNC

Attachment 313198 Here is a pic of what I can figure out. Is there anyways you could look at it and double check me to make sure I'm correct. I'm still VERY NEW at this. Thanks for all your help

0x378 is the normal base address of LPT1

I'm facing a similar beast, only mine has one more fang... it came with a 15-pin interface, and I had to go out and buy one of those boards, and now have to, shudder, transfer wiring from one board to th'other.

I'm puzzling over your informing LinuxCNC to put the SpindleON signal onto two pins: 1, and 17, and SpindlePWM on pin 16.

For my case, which I can only simulate at the moment as I wait for parts to trickle in, I chose to have SpindlePWM on pin 1 (which is what I understood the breakout board expected) and SpindleON on pin17, which I also understood requires the board to be "jumpered" to use the relay to power the spindle on.

My board also has pin 16 labeled "pulse" which is similar to, for example, pins 2,4,6 which while labeled "pulse" are actually "step" commands for the steppers. Makes me think p16 is for "steps" too. Again in my case, with the alternate jumper position pin 17 could be used for "B-axis Dir", in which case it would be sensible for pin 16 to be "B pulse".

Next to pin 16 is pin 14, marked "Enable." Maybe you meant that?

Keep in mind that, although I am not a newbie, I am comfortable talking through my hat.

If you've got this all worked out we, the rest of the world, would love a nice, family walk-through.

Thanks.
