hi rob..... errrrrr i might be lieing a bit..... we'll find out (ish)
25mm thk slides for the X and Y 20mm thk Z £250 ish
1605 ballscrews £300 ish
heavy extrusion £500 ish
20mm alli plate £400 ish
5 axis chinese stepper kit+power supply £260 ish
ball nut housings £150
so far thats £1860
im pretty sure iv spent at least £100 building 3 spindles including buying the speed controller
theres easy another £100 on odds and sods like timing pullies micro switches cable
i could be looking at £2100/£2200
it might be more though,,,,, stuff has a way of sneaking under the raydar :)
have a read of "fingers crossed it'll cut ally" you might spot somthing in there that iv missed

its quite an exspensive one for a first build but im pretty sure i wont need to build it again and its a lot cheaper than buying one off the shelf
