Torch Auto On/Off timing Problem

[Eijazz]

Dear All,
I'am working on T3 5x10, AVHC and Hypertherm 1250 Plasma cutting machine. Normally we make .DXF files in AutoCAD and after that import them into T3.
Problem is that when we start cutting multiple objects e.g square and circles etc, as we press 'Torch' button from "AUX PANEL" of Torchmate control software, torch starts moving downward to the object and immediately fires the spark and pierce the sheet but don't move on any X or Y axis until I press manually 'START' button from the "G-Code PANEL" of Torchmate control software to start the cutting (While I've made changes in M-Code definition and M-Code Execution as per instruction in given in the Help to start cutting automatically). Then it starts its motion on given axis and complete the cut of the required object. Without closing the spark and retracting back torch to its normal or safe height it continues its Rapid move to the next object while cutting and damaging the sheet and complete the drawing and stops cutting at point where it started the program. During this whole process spark remains on and does not stop automatically.
I'm too much confused with its behaviour, I'm unable to figure out the accurate parameter settings in AVHC and Torchmate Control Software.

Please, help me in resolving the issue.

Thanks in Advance

The Auxiliary panel is a way of testing the output relays on the system. It is only for testing the outputs or doing manual cuts.

When running a G-Code file, the Torchmate drivers software runs Automatic M-Code Executions, which is where the machine will automatically turn on and off the Plasma cutter. If the torch does not fire when running the G-code program alone, then the M-Code Definitions or Executions are not setup correctly.

Dear Mike,
Thanks a lot for enhancing my concepts about the "AUX Panel" of Torchmate Control Software.
As I understood from your reply is that "Once G-Code file is loaded into the Torchmate program, then I've to press "Start" button from the "G-Code" Panel to start cutting if other things are configured correctly, torch will start X and Y movement automatically and will produce spark for cutting according to the G-Code file program.
I'll try it very soon and will be back to you with the results.
Thanks .

Dear Mike,
Now I've unsatisfactory results with me. therefore, i'm attaching snapshots of the program parameters and the G-Code file cutting (for the testing and experimental purpose to fine tune and to be familiarize myself with the T3) with this post.

torch does not moves downward or upward unless until I press "Cut" button from the "Auxiliary Panel".
Please, help me in setting parameters, auto on/off and auto AVHC control through G-Code file.

Looking at the pictures you have posted, everything appears to be setup correctly. However looking at your g-code that you posted, you have inserted M50 and M51 commands at the beginning and end of cutting commands in your program. With the Torchmate software these codes are not needed, and in fact work against the operation of the system because it's automatically executing the codes behind the scenes. If you remove those codes there is no reason why the machine shouldn't run correctly.
