How to prevent the torch from moving up?

Thanks, I substituted those commands in the Postgui HAL file. Problem solved.
I think it is worth changing the main code. The program will become more general.
Cheers!

I will have a look over the next day or so.

What is the reason for doing this?

While I can not give technical details due to the confidentiality, it is to mimic QtplasmaC's THC feature to precisely manage vertical distance.

Dear Phillip,
I wanted to ask you if there is any way to disable the probing routine, but I found your following answer to a similar question:

"Probing in QtPlasmaC is controlled by the plasmac component and it is not able to be bypassed"

But, I need to use QtplasmaC/Plasmac configuration for my project Because I need to use the THC feature. I tried to activate THC by using M65, but it didn't work. As I understood, using M3 is the only way to activate THC.
Is there any way to activate THC without using M3?
Regards

No, it requires the M3 to begin the sequence.

There is a standalone THC component.

Is hard to help when the things are explained and the correct questions are made, but is almost imposible  if you can't provide  details.
