Hi you all
Can'nt afford anything like the Seig I'm affraid it has to be good old DIY. I like the plans available on www.crankorgan.com but not sold to UK. One thing I,ve noticed that if you buy butrussed lead screws they are coarser than studding and you are likely to need bigger stepper motors. The Seig uses Nema23 or 34 wonder what current they take?
Have been investigating software with aim of modifying my motor controller www.calenterprises.co.uk/speed.html for opto coupler. Unfortunately only Mach and maybe Zues are the olny ones to have a PWM output.
If I was making a mill I would use 3 inch angle iron bolted together to stant with then tack welded when everthing had been checked/adjusted. Square tube could be used for slides etc.

Happy Xmas Keith
