    Default Aussie Plasma Build


    Hi all, I'm Will from Queensland, Australia and I've decided to start a CNC Plasma Build. After drawing up some plans in fusion 360, Ive decided to jump in with both feet and give this build a crack. I ordered the steel last week and it come in yesterday. Living out in the sticks tends to make things move a little slower when it comes to the delivery side of things. But anyways I picked up all 900kg of it and we started cutting all the parts from the 4mm plate this morning. Unfortunately I won't be about to get to the table for a week or so but I'd like to share my build and get some input from everyone . Here are some pics of the gantry bits and some other parts we cut today and I started just dry fitting it.

    Yeah the parts were cut on a mates plasma cam table. I just find their tables to flimsy for the applications that I will require. I designed the table to be 3600x1900 as Im planning on making a lower cost custom design fencing and gate panels for customers, plus it opens up more opportunities. Scroll work gets expensive in labour and steel.

    Unfortunately due to other commitments I can't start until the end of next week which is frustrating

    Because of the decision to restructure the business and this is the last gate of this type I'm making and it'll go out the front of my house.

    Got started on the table made some cuts and laid some welds. The way it was designed I had to start making the legs first. Anyways here's some pics.

    The very first cut.



    Using laser to help level.




    Tacked squared and braced



    Welding it up.




    And welded up the feet.

    Overall dimensions are 3600x2100 and I've decided to go with clearpath servos. Cheers

    Will, good to see another Queenslander building a quality DIY Plasma table. Mine is only about 1300 x 1200 and after 10 months, I'm nearly there. The gantry is built so it won't be long before its together.

    Thanks mate. You'll be done in no time and it looks bloody strong to. It's hard to find Aussie cnc products but I'm going to give the masso a go for the controller.

    Thanks Will, my controller is running on the bleeding edge of LinuxCNC. When I get it going, I think it will be fantastic, no external hardware other than a $100 daughter card to read the torch voltage. Everything will be integrated with the motion controller but the software has been a lot of work.

    Your build looks great Will. I'll be following its progress from now on. Keep up the great work.

    Being outside the square !!!

    That's awesome Rod. Do you have a thread about the controller?
    Thanks ynneb, appreciate the feedback.

    Got more done, a little disappointed that I didn't get further but I made sure that I was perfectly level and I'm square and dimensionally correct to the mm. I'm bolted to the floor and once I weld a solid cross brace on underneath I can start the water table and remove all the temperory bracing

    Well kinda. I'm using a Mesa 7176e Ethernet controller and their THCAD voltage to frequency converter card that is designed for plasma applications. It converts torch voltage to a frequency that comes into LinuxCNC as an encoder count on the spindle input. You can read about my build here but I have not updated it for a while

    When you visit, make sure you check out the new plasma section which is where the bleeding edge activity is (including a few plasma components I've written). There is a still experimental branch of LinuxCNC that gives plasma the support lt needs includes a PID based Torch Height component.
