Motion Feed Hold Without Arc-OK

Hey ArcEye. I believe you got me there! After initial testing without plasma cutter on, I can get the feed to hold. I took your first set of code and inverted the arc-ok signal. That will allow axis to move into position, touch off to find top of material, enable torch relay and then just hold... and hold... While it was holding, I jumpered the arc-ok pins and feed hold released and axis movement continued. I will test fully in the next day or two.

As before, thank you very much!!!

Paul,

You can also use M66 to check your Arc-OK signal. Here is an example that waits 5 seconds after the Torch is fired. If it doesn't sense Arc-OK true then it posts a message and pauses the program.

You would have to add this connection to your HAL file (assuming digitalin-00 is not assigned to something else)
You could use the above G-code as an external subroutine which is called instead of M3.

Thanks Guncotton,

That is what I was using, but that only checks once. I was wanting a way to check for the Arc-OK at all times when the torch is activated.

But thanks for mentioning it,

Paul

With ArcEye's work, I think I have it now where motion is halted if the arc-ok signal drops while cutting (or never existed from the beginning of an arc start).

I ran it this weekend and did not have a negative effects like halted motion when it shouldn't have halted.

Is there another way? I'm using and2 and inverted arc-ok signal to accomplish the motion-hold.

OK
