Hi giladv,
Very interested in your project as I am thinking of building something of similar compact size in the near future and your design looks great.

I also use Kflop with my CNC mill and I love it.

One question, the 1.8 spindle servo, can you tell us what servo you are planning to use? Is is a dedicated spindle servo for higher revs or just the usual 3000 revs?
