    yeh I was going to chop a little out of the legs to get it closer to the deck to improve the stability, also the head does not move down any where near the base plate so it needs to drop down.

    Thanks for the help you guys, so to recap:

    Ditch the Vexta motors

    Buy two new 34 frame motors

    Drop the height of the x, y & z axis closer to the table

    But what kit do I need to get this running? drivers, breakout etc?

  2. Motors, Drivers, breakout board, power supply, pc and cnc contol software.

    Ok, so is any better than others as there seems to be a lot about?

    Also the software side, we use Machine Strat, Delcam & Bobcad here. Do the drivers need specific headers in the G-code text to run?

    Just Looking through a box of old motors I have here at work,

    There are three with the following detail

    1.8 degree step, Holding Torque 550mNm

    2 VDC 2.8A

    Are these any good? Noticed that you put down a torque of 3Nm so what is mNm?

  5. Normally stepper drivers are totally dumb and only react to clock and direction.
    So as long as you can get your software to generate clock and direction the driver should work fine.

    these drivers sound a little like me!!:dance:

  7. 3nm is 300mnm just like 300mnm is 30 ncm.
    5.5Nm is a reasonable amount of holding torque and if you use the existing belt they should give you enough torque to run the machine, but you need to define what you are using it for to determine how much power you need.

    I want to build a router out of it, mostly for machining wood, but would like the ability to do the odd ally job too.

    why, what wrong with it?

    Maybe so but itís a lot better than some of the tat I have seen floating around, thats for sure. I donít need a massively robust machine, I own an aerospace tool room with many CNC machines, I just need this machine to help my dad who sits at a desk making 100's of wooden miniatures by hand, as his part time business. Just wanted to help him out a bit.
