    CNC Plasma Project

    Hi everyone! I'm new to this forum. I'm a welder by trade and have been in the industry for 5 years (1st year tradesman). I work on a mining site in Tasmania Australia. Just thought I'd share some pictures of my CNC machine that I have constructed in my spare time over the past year. Let us know what you think!

    -Geckodrive G540
    -CandCNC LCTHC
    -Thermal Dynamics Cutmaster A120
    -Mach3 & Sheetcam

    Travel dimensions are roughly 1400mm x 3000mm.

    1605 ballscrew torch height control & rack/pinion long travel.
    Nema 23 stepper motors

    Magnetic breakaway torch mount

    Water bed with drain/fill pumps plumbed to external 1000l tank

    First welcome to the forum. Just something I noticed was that you slides on X axis are unprotected from the dust and sparks from plasma cutting. Do you think that will be a problem for the long term?

    very nice looking table your going to have fun now.
    The only thing I would do is mount you slats so you have a curve is them maybe off set the center by putting the center in the next groove over right or left. Straight one seem to wobble when the torch changes directions.

    Thanks. Yeah i'll keep an eye on it once I get the unit running & may have to develop a cover then!

    Thanks for the heads up. I can flip the center slat locating bars which will offset them. May have to give that a go

    I'm with acourtjester, get those slats curved across the table, it also prevents following if you're cutting straight lines.
    I'd also be inclined to close them up a bit, maybe 50mm spacing.
    I'll do that, makes sense. How will I benefit by closing the gap?

    I guess it depends on what size designs you're going to be cutting.
    I actually have the option of 25mm spacing for the smaller stuff.
    Thanks for the advice! I may have to modify the slat setup at some point. Appreciate all the helpful tips.

    Re: CNC Plasma Project

    I originally got plans so worked off that too start off with. But the engineer who drew the table hadn't taken into consideration a lot of things. E.g longtravel with a 1605 ballscrew over three metres long......slats above water level by 100+ mm therefor defeating the fume collection aspect. Not 100% sure yet, probably more decorative kind of stuff. Gates, signs, fence panels etc.
