Plasmacutter on T2 software.



  • Hi. Im a guy from Denmark. So please, before i try to explain my issue, i wanna excuse for my bad English ;)

    Well i Just bought my first laser engraver (Amazon type, Sorry) my plan was to build my plasma cutter on. I bought T2 laser software, Yesterday because the software it comes with were shit!

    Now to my question, My plan was simple to connect a reley on the laser wire that will give signal to my plasma cutter (to start). But my problem, is that the laser has no preburn time. Is it possible in t2 to set a Preburn? so my plasma has the time to cut threw the iron before X any Y moves.?'

    Hope you understand.

  • HI Zax.

    Well It´s only working, but only on the first "cut". If i have a dxf with multiple holes, the laser don´t turn off between the holes? Do you know why?


  • Developer of T2Laser Software

    @hypermagic Is this a plasma without Z-axis? If so do not select the CNC Mode, just check plasma mode.

    Does it respond (turn off) when given a power 0 signal or does your controller need M05?

    You may need to select a different post processor or it could even require a minor update.



  • No my machine is without Z-axis. Still not working. if I check off CNC Mode, and only plasma, the laser dont turn on in the "delay time".

    If I turn the laser on, It stops if i press M05 .


  • Developer of T2Laser Software

    @hypermagic It sounds like your machine only responds to M03/M05 and not spindle/power values, so this would require a different post processor. What firmware are you using? (so I can determine what settings you need to use)



  • Default firmware. https://ibb.co/3m6Hjjy


  • Developer of T2Laser Software

    @hypermagic So the software and firmware are sending spindle power values but it appears your machine does not support them, M03 S0 should turn the plasma off (similar to M05). There's a post processor which will change M03 S0 to M05 but then the problem is you won't get the start delay on the next path, I will modify the plasma G-code and publish an update later today. Please e-mail me or contact me through my website so I can provide a beta key to allow you to immediately test it.



  • Damn, thats what i call great service 👍 Looking forward for the update.. I Will send you an email.



  • Hello, I´ve just put together my CNC and have the exact same idea as @hypermagic! were this successfull?

    going to make som more tests with just the laser before hooking up my plasma, guess i´ll find out sooner or later anyway... is the update @Zax talking about anywhere to download or is this integrated in t2 nowadays?

    (T2 seems great compared to recomended software for my cnc BTW!...) old topic, someone else tried this approach?

    @tobiasdahlgren87 T2Laser v1.5y is the latest version and includes plasma support. If you are on a previous version it should automatically update or you can click Help / Check for Update.

  • thanx for superquicke response! I will try this and get back as soon as I know the outcome!



  • finally I could say I´ve tried this. And it works GREAT!

    Even got my plasma couple of days ago and it does´nt seem to stall or interfere with the CNC system wich was my biggest consern, not done any fancy testing yet, just ran the CNC with laser and cut manually with the plasma quite close to where I will mount the plasmahandle. hopefylly i get to try to really fabricate something soon.

    one question remains though. is it posible to make some kind of priority order wich lines comes first and so on.
    I´m worried that many times it´s going to cut the contour first wich will result in movement of the piece and probably ruin the rest of the cutting...

    Maby one have to cut and paste the code to make it work? or just remove a bit of line and leave the piece hanging till it´s done with the "internal" cutting...

    BTW the plasma is a stamos s-plasma 85H (not the CNC since i want to be able to use it manually to)

    Edit: made a quick test and it seems to be quite simple to just find the code for the contour and move it to the bottom to get the contour to be cut last, even without any pre-knowledge of how the G code works!


  • Developer of T2Laser Software

    @tobiasdahlgren87 T2Laser defaults to following the DXF order, but you can use the DXF Optimizer to define the sequence by the color.

    Another way to do it is using sequential mode but that's for CNC tool changes, it will stop and ask you to change bits which of course doesn't make sense with a plasma.

    If using the first method, so color is used for sequence you will probably want to set Absolute DXF Colors to 0 so every color has the same value (that is certainly the case with a laser but may not matter with a plasma).



  • Alright! With use color for sequence its possible to control the contour color to always be last in the code!
    problem solved!

    This is getting more and more spot on =)
