plasma post prosse

[ELIKO]

Hello friends!
I built a plasma cutting machine. (It's not easy at all). The parts I purchased on eBay include a DDCSV2.1 controller from China. I purchased SHEETCAM software including a license (meaning I do not work with the demo version which is limited). The problem is: 1. I do not know which post processor is right for my controller. I tried various post processor from a long list. Some did not work at all and some did not work well enough. The problem is that as soon as I press "Start" on the torch controller (M3) it immediately starts working and does not stop even when new layers need to be stopped and restarted. In some cases at the end of the work the torch continues to work and I turn it off manually.
In the simulations I do SHEETCAM everything works fine and it shows me when the torch is working and when it is not.
Would appreciate help!!!
Thank you
ELIKO

You need a plasma post processor. Try the 'Mach3 plasma' post.

Hello friends,
First want to thank for the advice.
I tried all the variations of MACH 3 and 4. Unfortunately it did not work. I also tried a post of LINUX PLASMA CNC. It works but again M / 3 immediately goes into action and stops at the end of the operation. this is very frustrating. Would appreciate help.
Thank you

What commands turn the torch on and off with your controller?

[ELIKO]

Hi,
The command m3 on m5 off.
Thank you

Hello again and thanks for the help attempts.
After I went through almost all the relevant postprocessors, the glitch continued. The M3 SPINDLE is immediately activated. Switch to another software I found on the net and unfortunately the same problem. The conclusion I have drawn that I am performing an operation or setting incorrectly in the electronic controller. If anything has an idea before I replace a controller I would love to have. The controller is DDCS V21.
Thank you

I found the manual online and as far as I can see it should work. You do however want to set parameter #224 to 0.

Could you post a copy of your g-code here so I can take a look.

Hello again and thanks for the effort.
I drew a circle size 50/50, downloaded to SHEETCAM.
Post process "minimum gcode"

The 'Minimum g-code' post is for milling/routing. Try the Mach3 plasma post instead.
