For a while now I've been looking around to try and find a realistic way of DIY CNC. I don't mean go out and buy a CNC for £2000 and work it at home, I mean construct a viable Desktop CNC machine on a realistic budget. Currently I am thinking as close to £600 as I can get.
It seems that if I were in the U.S. then this can be achieved by buying from a range of ready made kits that range from $500 upwards. As always though, very few of these ship to the U.K. or if they do then the cost is extremely high. One seller on ebay told me the kit was $699 and it would cost me $650 to ship it to the U.K.
Its mainly because the cheaper kits are MDF framed or something similar and its extremely heavy. Aluminium is a lot lighter but proportionately more expensive.
It also seems that manufacturers of the kind of hardware needed to do this in the U.K. know that they have you cornered. Leadscrews, Ballscrews, Linear Shafts and bearings all cost more here than abroad. Stepper motors and Controllers cost more but they can be imported for not too bad a cost from the U.S.
These for example are used a lot and recommended on many sites.http://www.probotix.com/3_axis_stepper_motor_driver_kits/
Surprisingly, a similar solution can be bought here in the U.K.http://www.diycnc.co.uk/html/driver25.htmlhttp://www.diycnc.co.uk/html/stepper_motors.html
If anyone has any experience of building this kind of thing I would be interested in hearing from them.
