If money was no object I would go for the servo motors.

Do you have a link to a good MPG for 30 or 40€? The ones I found were approx. twice that.

Depends if your just talking about the MPG pulse generator like hannu probably is or what people often mistakenly call MPG but should call Pendant with all the other controls on it.?

Here's 2 of the MPG pulse generators. 25 pulses per Rev and 100 P/R. 100 is most commonly used I think.!

Hi JAZZ - yes absolutely, some way of fitting an end stop is very practical. I also realised that the "overhang", or working distance from the face of the dovetail jig, is only 91mm. So maybe I should extend the Y-axis rails by 50mm or so.
Thanks for the links. If this is the type that hanermo2 uses, I guess that you will need 3 - or maybe the Pendant type is just as good?

It seems I am getting close to having a mechanical design that will fulfill my requirements. However, there is still one point on my list that I need to look into. I would like to have some kind of adjustable bed. I will mainly be working with wood, so I think an MDF plate will be sufficient for that, and also with wood the fairly long Z-axis will not be a problem. But for aluminium I think it will be good to lift the bed for better stability. This bed could be smaller and also have provision for clamping the work material.
Something like this:

If anyone has come up with a mechanically good construction for raising/lowering the bed, I would love to have some info/links.
