So post Christmas update 2021.
Still haven't worked out spotting in Sheetcam, or how to se the tool from QtPlasmaC instead of Sheetcam. Must need to watch more video's.
The original plasmac post for sheetcam required a seperate tool defined called "Centre Spot"
You then did a seperate drill operation using that tool.
This required you to move the holes you wanted to spot to a new layer.
The default sheetcam post just needs a drill operation with any tool.
Thats about it.
In the gui, set the spotting threshold for 10 volts and start the delay at 0.5 seconds.
What should happen is plasmac will see the voltage threshold exceeded. Then it will wait for 0.5 seconds or whatever you set and turn the torch off before you get an ArcOK.
This should result in a finer spot than would normally be achieved.
The time delay is very machine dependent. If it does not work for you (eg torch does not turn on), try extending the time delay.
The reason why we wait until a voltage is seen is that different plasmas and relays have different lag times from the time the torch is activated so it allows for this.
