Hi Rob,

My build log is for a machine I built from aluminium extrusion http://www.mycncuk.com/forums/gantry...its-begun.html

As a word of advise I would say using extrusion is going to be more expensive than box section steel and you are really saving yourself the time learning to weld (and the cost of the kit if you need to buy welding gear) or the cost of getting someone to weld the frame for you. Extrusion I would not say is quicker either, as you'll find out after tapping a couple of hundred holes for bolts ;-) Its simply more convenient and easier to get going on a build for a "non welder".

That said my extrusion based machine is operating pretty well these days and one good advantage of building the frame from extrusion is that adding stuff to it is generally easier as there's lots of slots to bolt stuff to (sensors, stops, additional bracing, 4th Axis etc).

There are others, but I went with a 3 axis 3nm stepper motor kit from Zapp Automation, which iirc came with motors, drivers and PSU. I would also highly recommend the 2.2Kw water cooled spindle and matching VFD you'll see mention of in many threads over say a normal air cooled router spindle - they are per Kw cheaper than the router you linked, very quiet and take a range of tools with a suitable set of collets.

Last bit of advise is to get a Sketchup design on here and await feedback from the likes of JAZZCNC and Jonathan etc. who helped me massively in getting a less than half decent design to an almost fully decent design :-)

Best of luck with your build and hopefully we can see a new build log soon.
