Amazing!

If you're measuring at the PP output it would be around 0V in its low state and around 5V (or 3.3V depending on your PP card) in its high state.

Since the step line is a square wave, and not a constant DC (nor a 50Hz AC), the voltmeter will show just "something" based on its interpolation technique. It is not a value to judge by the output correctness. But since the value does change, you can tell that signals do go out of the breakout board.

Hmm.... I remember someone was having a problem with lost steps here and he was reporting that his direction pins' state was not changing, but rather he was seeing pulses on the direction lines. It's an abnormal condition (don't remember if he reported/found the cause), but may be it's what you're having. Can you try measuring the spindle relay output? Try to toggle the spindle ON and OFF and see if it changes state.

Otherwise, looks to me like you're printer port is not functioning properly. May be reinstalling it or something could help...

Hi Robert,

Just to make sure Mach3 has been properly installed on your PC including the driver itself, run the driver test file located in the main Mach3 folder.

Also make sure the offline button on the main Mach3 screen is not active.

Scott,

I see what you mean. No point then adding the H DRO which would display the obvious.

Scott,

Not sure what you mean by H for same tool. If it means displaying the current offset NUMBER (not the actual offset length), then it's perfect. That's what's needed - no other thing.

Looks good, Scott. I still think the Spindle CW and CCW icons are a bit confusing - look like undo and redo to me Wink I think if you add a cylinder beside the arrows they would look better.

Did you find the way how to add the tool offset number DRO?

Hi Robert,

Use your Fluke to measure the voltage of one of the pins directly on the PP cable connector. Unplug it from the C11G, put one of the probes on one of the direction pins, say pin 3, and the other on any of 18-25 (ground). Now using the arrows of the corresponding axis, jog it alternately each direction. The direction pin should be changing its state and you should see the readings reflect it.

OK. Thanks. The way the F1 is, I think I will not be able to connect the two sides. I think the only way is doing two drains, one on each side, and interconnecting them underneath.
