CNC Plasma Cutter turn on the torch

Hello everyone we have a project that is CNC Plasma Cutter, and I am using the software "Universal G-Code Sender" which is connected with the Arduino UNO. How can I automatically control the firing of the plasma cutter when the operation starts (the torch starts to move, tracing the drawing) and then turn off when the operation ends?

Need help guys.

This is a new question so I have suggested to the Moderator to move it to its own Thread.

I suspect you will more easily get an answer on a Forum that deals with CNC stuff. This Arduino program is for helping people write their own programs.

My wild guess is that the switching of the cutter needs to be included in the GCode by whatever software you are using to generate the GCode. Then UGS just sends the GCode and the correct things happen.


A suitable relay connected to Spindle Enable may suffice.

However you have not given any real details of the setup so that is only a guess.

Better for you to READ THIS PLEASE then add extra information.
