Hi Devastator,
I built a Solsylva three years ago now and its still running strong. I had an issue with the blue screen zeroing, and found out the original VB script you can download had bugs in it. After going after this problem myself, I posted a script that worked correctly and never had an inadvertent plunge after that.
That's one of the problems with the Mach add-ons - there is no central place to get the latest working version, and the older buggy versions seem to hang out there indefinitely.
I posted the script here:

Then I started using Ger's 2010 screenset with its own much more interesting zeroing capabilities and never looked back.
If you want a look at my machine, Snailworks CNC Builder Log is where the build log is. Hope this helps,
