diamond: Re: [DIY-CNC] Anyone care to check my plans over, before i order the frame parts?

Hi Peter,

The metal work will cost about £350 ish, cut, and thats about my final purchase. (and, yep, im in england)

I havent yet totalled up the rest of the costs - they wont be insignificant, but will be considerably less than that of an 'off-the-shelf' machine.

The parts ive already acquired are -

1x THK KR33 (400) (y-axis)
1x THK KR33 (200) (z-axis)
2x INA guides (with two blocks per rail) (x-axis)
1x Kuroda Ball Screw assembly (x-axis)
3x Parker drives / drivers
1x Break-out board
1x New Hemes spindle (engraving)
1x WGE spindle (pcb milling)
1x Kress motor (steel routing) << this is the only bit i had to buy new - oh, appart from the metal work : )
1x 28v 20a DC supply (for drivers)
1x 48v 7.5a DC supply (for non-ac spindles)

I realise a lot of the units are way over-spec'ed for my use (like the THK KR33 on the z-axis!) but theyre what i had access to, and a lot of the parts have also hugely simplified the build - for example, the KR33 devices are complete units that can just be bolted on (ie ball-screw + slide + mounts + bearings)

As i dont have access to (or would have had to pay for) the machining needed to build a more complex device, ive been trying to go for somthing good and simple, but still with good capabilities.
