Hi
I have developed a method to center punch locations for drilling holes on my PlasmaCNC setup.I use CAD software (Fusion 360) to locate where I want holes drilled in my finished cut parts. I use fusion to show the location and size of the holes and then use the snap function to locate the centers. I do this with the circle sketch function snapped to the center then draw a 0.003” dot there. After saving in DXF format and importing into SheetCam I change the layer of the dots to separate the center punching from the normal cutting operations. I then have a tool in SheetCam that has the perimeter for the center punching operations. This has the pierce and cut height set at the same height and lower the Amps some for this operation. After planning the whole operation I select the center punching functions into on G-code and then the cutting function into another G-code. SheetCam will ID the center punching as a inside cut and you can make one G-code where it will do the 2 operations in the same G-code. QTPlasmaC seems to have a quicker response for this operation then I had with other controller software, but both produce a very nice dimple in the metal.Attached are images of the center punches and a video of the operation.  I have used this method on different thickness metal with thin metal using the fine cut nozzle. I have used it to create a template for hole marking by center punching a thin plate to transfer the locations on another project surface.

Try omitting that line with scalemax, right now i can not recall i ever used it.
Just add # in front of the line, save, test.

I use Ditron magnetic scales all the time. Installed my first ones in 2019 on my 5 axis machine. Since the I have used installed about 20 of them. Not a single failure yet.

Be sure to specify that you want 1um resolution. Reader head model DMR2000. And also specify that you want the index pulse version (z signal) otherwise you get only A and B.

Yes. They are differential output

We've got plenty of trees, but the city white fellas cos playing as black fellas wanna stop everyone walking into where the trees are, unless you're a black fella.
The real black fellas are good fellas.

Now before everyone gets their knickas in a knot black fella isn't an insult, it doesn't matter if ya a black fella or white fella what matters is to be a good fella.

There's large swathes of land here that are off limits unless you're Aboriginal.

Hi,
only one 7c81, you tip has done the trick. Thank you!
but the next problem occured
The error changed to:
/intos.hal:88: parameter or pin 'hm2_7c81.0.7i77.0.1.analogout0-scalemax' not found

so checked this line in the old, working hal, without the 7i78, and its exactly the same. What does change here when i use 2 daughterboards?
Any Ideas?

EDIT:
i have also tried to change the channel number to 0:
hm2_7c81.0.7i77.0.0.analogout0-scalemax'
and 2 and 3
