Looking at the specs they appeal to me. My motors come in @ 1.75kw so they are within the requirements. The only drawback which is a small one is that I have 3 axis (X,Z,W tailstock turret) and would require 2 boards. Which would give a spare if needed, I am not sure if I want something sitting there not doing anything, but they are an option I have been looking at.

I have had no problems whatsoever with the drive. It works very well. You do need to build your own power supply. This can be fairly simple, just a large transformer feeding a rectifier and smoothing capacitors. At this power level you do need to pay some attention to power switching. I use a contactor to switch the transformer AC output to the rectifier. The contactor has an auxiliary N.O contact that switches a 100W discharge resistor across the capacitors when the contactor turns off. This discharges the capacitors quickly, making sure the machine stops quickly even if a drive fails. Les On 19/08/2011 01:40, cl...@clintandheidi.com wrote: > I have looked at the mesa's.

Do you have an example? ---------------------------------------------------------------------------- -- Get a FREE DOWNLOAD! and learn more about uberSVN rich system, user administration capabilities and model configuration.
