Andrei, I would strongly recommend you look at this http://www.machsupport.com/wp-conten...3Mill_1.84.pdf You could even print it and take it for bedtime reading if you suffer from insomnia

Seriously, I would skim through it so you are familiar with where to look to solve specific problems. There is a lot of documentation on the mach support site.

I use Estlcam and for the small cost of a license, it is impressive. you can download for free and you get a fully functional copy, but there is a software time bomb in it, so it may cease to function after a while.
