    I have a X2 Harbor Freight Mini Mill and want to use The CNC Fusion Conversion Kit can anyone give me a list of everything else i will need to get this complete? I plan on using the Mach 3 software. Thanks Mike

    ETA: I have a computer that i plan to use only for this mill.

    I'd be interested in helping you
    I have only done a sherline mill and lathe but I am planning a larger build for a zx45
    here also is a good site with some information on your x2

    and here is a review on the kit your concidering it looks nice if your not making your own
    http://blog.makezine.com/2011/12/06/kit-review-mini-mill-cnc-conversion/
    I used the original lead screws on the sherlines but for anything larger i'd go ball screw for backlash reasons the sherline needs constant backlash adjustment to hold accuracy.
    I can also help you find the softwares you need I have mach3 and for the most part everything else i use was free or very low cost.
    Illness is keeping me out of my shop so I'm bored and happy to help

    Would the 260 oz in stepper motor be enough to machine aluminum and delrin?

    I use 276 oz in on my sx3 conversion for x and y - no problems machining anything I throw at it. Don't consider the motor in isolation through - some motors of much higher rating may not develop anywhere near their rated power because the driver electronics/power supply you have chosen are not up to it. Consider the whole solution.

    really like to see a nice write-up with pics as you do the conversion.

    I used the cncfusion deluxe kit for the conversion of my sx3 and it was excellent. The finish on the parts was perfect and everything bolted in place. My only criticism is that the install video is very dated - he has moved on substantially from then. Shipped in 2 weeks as stated on the web site.

    Consult the cncfusion forum (access from his web site) for build threads.

    that probotix kit is way over priced and under powered the motors a 280 oz/in holding torque but the drivers and power supply are too small those drivers sell for 6.95 check ebay under stepper motor drivers list low to high when you hit $10.00 you allready passed these cards value . they are sucking in newbies with the 280 oz/in

    just an example this is stepper drivers at up to 50v 4.2 amps an opticaly isolated breakout board to protect your computer and 3.0 amp motors 287 oz/in. the power supply is 36 volts 10amps this setup is 4 times better than what you are looking at with the same size "holding" torque.

    the probotix parts are all chinese also they are just sold here under their name

    that kit was worse they are giving you 1 bigger motor and a tiny power supply 24v 6.5 amps sucks drop that site they are ripping off newbies by selling as kits and motor size nothing to power the motors

    Check out the packages from Kelinginc. #2 is comparable in price to the second package you posted, but with larger steppers, and a beefier power supply. The drivers are also bipolar drivers vs the unipolar drivers from probotix. The Kelinginc kit does not come with a parallel port cable, but those can be had pretty cheap, especially if you have a local surplus electronic store. The probotix kit doesn't look that bad, but a 24V 6A supply seems underpowered for 3 steppers. Of course, I got the largest servos I Keling had when I did my conversion, so I may be guilty of overdesign...

    it may seem confusing but stepper motors are driven at much higher voltage than the motor says. up to 10 times higher. the higher the voltage the lower amperage the motor draws and you get more power out of the motor. in order to do this the motor controller has to be able to handle higher voltage and amps or you will have no power. its like dead batteries the motor will run but no power

    see the kellings are running 36v 9.7amp much better the torque rating is holding torque not running torque running torque increases with higher voltage and amps these same motors at 48v 8amps will be way more powerful
    the power comes from the power supply voltage and driver voltage/amp limits
    also the faster a stepper turns the less power it has
    the direct drive ballscrew kit you are looking at gets the most power out of the motors

    I'm planning a zx45 mill with 2 1600oz/in for x and y and a 4200oz/in for z
    with 3/4 ball screws you cannot overbuild
    this mill is going to base price out 3 axis at $3500 including the new mill
    i put the parts list and part numbers in a post i'll find it if you want
