"Hold" command for arc controller unit.
« on: September 02, 2008, 03:35:32 AM »
Is it possible to have a "hold" output for arc controller unit?
When using arc controller, the change of speed can affect the torch height.
What i want is: at the corners (where speed is lower and the torch will touch the plate),
the mach3 will give an output to the arc controller unit to hold the torch.
Can that be done with brains?
Any ideas on how to do that?
Kind regards,
Giannis

Not 5really sure what you are meaning by a "hold" for the arc, are you meaning you want to stop the arc while you turn?

No, i mean to stop the torch moving up/down when the torch is near the corner of the shape, or when the speed is lower than 90% (lets say) of the maximun cutting spped.

Should be doable in a macropump depending on how the height control is operated. What you could do is have a DRO that you put the speed in at which you want the height adjustment to stop at and then your macropump would continually look at the feedrate DRO and that DRO  and if it dropped below the set speed then it would switch off the output to the height control, once the speed went above what you have in the DRO it would switch it back on. This however is all dependant on whether Mach is controlling an output (Input to the control) for height control.

And now, how can i create a macropump?
Is that a brain? Or a macro?
Give me a few tips about it please.

You may be able to do it with a Brain, I dont use Brains much (my own included ;)  ) so I would tend to do it in a macropump.
 How does your Arc Controller work at the moment? What I mean by that is it controlled by an output from Mach to switch it on and off?

Hold on!
There is an antidive option already in mach

Set up an OEM button to turn it on and off at will, oem code is 221 for the button and 70 for the led.

It basically freezes the torch movement as it goes through corners
