 ??? Members documents? Where?

How do I read a value to a led or dro from my PLC? I can switch PLC outputs on and off from mach with vb script
but not the other way around.

Hi Jim

Your prayers have been answered,  ;D , there is a free PCB program with a mach post processor (limited to 250 points I think) for hobby use.

General Mach Discussion / Re: simple AC servo speed control?

I have never tried it, but theoretically it should work.
The motor should have three phase wires and an earth.
If you use a vector drive, set the maximum output voltage to 200V.
Most sensorless vector drives need you to enable the vector function and then to select autotune.
Also remember that a servo has multiple poles, so you might have to set the maximum frequency very high.
to get the rated maximum speed for the servo.

Download the oem codes.xls link: http://www.machsupport.com/forum/index.php/topic,6657.0.html

In screen4 select "VB function edited in mach" for your buttons.
Save and close screen4, open mach - operator - edit button script - insert code.
eg:(toggle button)

If GetOEMLED (78) Then
   DeActivateSignal(Output5)
Else
   ActivateSignal(Output5)
End If

Every punching job is different. The cad drawing is made in 2 layers - 1 for punching and 1 for cutting.

To get the overlay exact it is more accurate to set a reference point on a punched mark and set the angular offset on the other mark. I cannot drill the table, as it consists of a supporting grid.
There are plasma machines that do this - some with video probes and others with laser probes.
 I just have to figure out how it is done.

Hello

I have a plate that is already punched with holes with 2 reference holes on the edge of the plate, now I want to plasma cut the plate.
Is it possible to use a laser probe to set the angular offset and zero position of the X and Y axes to align the plasma cutting and punching?
