Hey Hugo,

No problem at all, you can write in Spanish and I'll reply in both languages to give others a sense of what we're talking about.

I hear you about the new toys. I think we all go through that. My machine is a gantry type roughly 5' x 5' made out of 80/20 aluminum (#1530 and #1545). I've also added a 0.5" thick steel plate on X for rigidity. I started with a wood router as a spindle but quickly found out they are loud, run hot and have poor 'run out'. Run out is the distance the spindle deviates from it's center. A large run out translates to poor finish and/or broken endmills and bits. So I built my own spindle and turn it with a DC motor (<8000 RPM). I run the steppers at 36V and they typically draw no more that 2 amps peak. I've neglected my build log for sometime now but here's what I have so far: http://www.cnczone.com/forums/showthread.php?t=5302
