Easy Servo Drive?

It's a bit late now I've got the ESS, but what do you think of the PoScope Jazz? Looks like more functionality for a lower price.

I've got one and it's ok but not has good as the ESS. Also to get the full functiinality you have to use USB rather than Ethernet which is a let down.

I'd like to say thanks to Jazz for recommending the smooth stepper to me, even though my original post on the subject was about servo motors!

I've got it installed now and cut a few things. The increase in accuracy is quite noticeable, even running at a higher speed. :)

At the same time as installing the ESS I did also upgrade one of my motor drivers so that will no doubt help, but I've gone from rapids at 6m/s to 10m/s and cutting from 4m/s to 6m/s and still seeing higher accuracy.

Worth every penny.

Thanks and your welcome. It's actually quite hard to get across to people the difference an external motion control card makes. It's more than just the speed and more to do with the whole way the machine performs. Has you found out even the sound of the machine changes.

Being from the MotorCycle Racing background the best way to describe the parallel port is like comparing the sound and performance of clapped out Honda 90 to Honda RC166.!!. . . . Close your eyes and listen to this 50yr old bike.!!!
