    its done

    well I have finally got my plasma table built using drive belts ,using the info from here and there.
    I have had great results so far, in fact had to make sure the dti was working properly!
    But it was..
    have a 1500 x 3600 table, and when running it up and down the full length of the table was getting as low as 0.04mm out.
    Am not running linear bearings at all, just plain bearings running on a "C" beam i had ground up.

    But i am a true belt convert.!!!

    The cuts I an getting are great.
    In fact the only thing letting me down at the moment is the Z axis, which is ball screw.
    I hope to get some pics sorted out later.
    But for those of you wondering if they really can work in real life.....
    Yes they do
    As to how well they will cope with the dust.. only time will tell.
    But at the moment mine are doing great, even with water all over the rails, from the water table.

    Are your products available yet?

    Hey Mike,

    I was looking at your ServoBelt stuff over the weekend and it is very impressive, it makes me want to change my major from Biology to M.E. Anyhow, I was reading a few of your threads and I noticed that people have asked about your products being available to us common CNC hobbyist. Do you have any updates on products and pricing available for us?

    First post on this thread but am completely awed by this design. Now I am hoping it will work for my app.

    I need to build a machine for making some of my products and want to build it heavy. The spindle could be anything from one of the atc chinese spindles to a 5hp Colombo kit.

    The machine is a moving table design with a movement of about 24" on the Y, 60" X and 20" Z. The table will be the Y axis. This should make the weight distribution more even on the X and Y.

    I currently carve laminated wood in 3d at 100ipm. I would like to carve much faster than that. Will this belt app work (diy) for a heavy X (200 lbs) and a matching weight on the Y? The Z should be around 75 lbs.

    Weird, but I seem to not get alerts of posts here.. Thanks to recent posters for the kind words. Still no solid ability to supply DIY'ers, sorry about that. I'm still thinking it will happen.

    Mike, I'm not sure I understand about the X being 200 lb, is that the estimated weight of Z stage and spindle package? The Z should be a screw, I'm thinking.

    Hi Mike,

    Thanks for the post. The combined weight of the x carriage and the complete z axis will be about 200, maybe as much as 300 lbs. The z axis will most likely use r/pinion.

    I am curious if this will move the combined weight of the x and z axis at the speeds I want/need?

    Since its belt drive, how do they factor in the wearing and stretching of the belt over time?..

    And under load there must be a factor of stretch?
