I´m having very much problem with turning the THC on in a gcode.
Included are the macros I use for turning the THC on and off and the file which I test the function with.
By them self the macros work fine, and if I delete the M101 in the gcode file it also work fine,
but when I run it as it is now it turns the THC on and then the Torch, and then nothing happens?? until I hit stop and the run again, then it continues, its like there is something wrong with the macro that I have to abort with the stop button.

I have also tried to move the M101 after M3 and then it hangs after M101.
There is no problem with klicking the THC button when the program is running.

I have been trying different approaches now for two hours and are supposed to have this ready for a customer on the morrow (in Sweden that is) so if anyone could help me it would be much appriciated.

M101 macro:

Rem THC On
If GetOEMLED(24) = FALSE Then
   DoOEMButton(123)
End If

M102 Macro:

Rem THC Off
If GetOEMLED(24) = TRUE Then
   DoOEMButton(123)
End If
   
Gcode:

You are going to have to add some logic to the  M010 M102 macros to determine IF the Thc is off, turn it on OR if the thc is on turn it off.

They way you are doing just toggles it reguardless if it is right or wrong.

Normally you just turn the THC on and leave it on. There are only a few instances where you would want to turn it off/on via Gcode Also there can be delays in macros so the timing of execution is not perfect.

You can set teh anti dive to do MOST of what you need done THC wise.

Just a thought, (;-) TP

How do you mean? thats exactly what the macros are doing:

M101 macro:

Rem THC On
If GetOEMLED(24) = FALSE Then 'Check if off, then turn it on, else do nothing
   DoOEMButton(123)
End If

M102 Macro:

Rem THC Off
If GetOEMLED(24) = TRUE Then
   DoOEMButton(123)
End If
   
I want do be able to set cutting rules in sheetcam to control the THC, thats why I want this to work.

My Mistake I misread your LED num. I thought you were looking at the torch LED  and then toggling the THC.

I tried you code here and it runs FINE.

Are you getting any error other than a stall.
