Rich and Gerry, thanks so much, I'll will try these adjustments that you have suggested, and will do better research on all the components when i build my own larger table. One last question for now, I was a little shocked when this came through with composite nuts, I figured they would have been brass, I also found that using a silicone base spray on them has helped greatly reduce the vibration and wear from the dry nut and screw. Do you suggest any other lubicant or trying to find brass nuts?

I use plastic nuts from www.dumpstercnc.com and lubricate them with a light oil. I use pneumatic tool oil.

I think they still should go much faster then I can get them to go

YES, but your voltage limited, the  time required to get the current level up  ( think of an RC circuit, becomes inductive rather than resistive ) is dependant on the voltage which affects possible motor speed. They don't give your curves for different voltage levels other than say 24 volts. As the pulsing is increased, your pulsing / waveform  being sent to the motor reaches a point where it is very unsatisfactory and thus you reach a max motor rpm for a system. SYSTEM means your power supply, drive,and mechanical / machine, thus,  all have an effect on the preformace.

You may want to have a look on the Gecko site as they have a lot of  theory / info explained better than i could ever present .

I've noticed that Gecko is mentioned more times then not in alot of different posts, I will check that out as well, again thank you

Gecko drives are the standard that others are judged against. When compared to most hobby level drives, they'll give double the performance.

Again, 600-800rpm is the best you can expect. Especially with the small motors you have.

Hmm......practicaly speaking, for most hobby machines, there are enough folks in here with experience on all the variations on the the theme,
such that expectations can roughly be know without a lot of techie stuff......just depends on hearing the song....... ;)
