Best Type of Machine to Build?

[irving2008]

400mm spacing seems a lot....Mine are 200 taking 200 off the available total travel with the cutter located central... Have you made one yet Irving?

OK my maths was out, should have been 800 x 700, it was 200 on each axis.

My PCB router is 600 x 500 for a 350 x 280 working area. Fixed gantry, table moves in X only. One day I'll get the Z finished and machine the leadscrews (when my lathe is set up right). Just got the driver PCBs from PMINMO.com and assembled most of them last night but waiting on some more bits from Farnell today hopefully.

Thank you all for your help. Think I will probably start with a smaller fixed gantry type machine - will give me some experience of setting everything up and getting things moving! Then hopefully if I get it working I will be able to use it to make some of the parts I need for the larger machine.

Off to sort out motors and driver boards! hope to start a build log soon - so you can all see what a mess I make of thislol
