Not bad  I think I will check them out some more as I will be building a couple more machines smaller than my big one.  these may just do what I want. Thanks

Gecko make nice stepper drives, so if building a small machine it would be what I would look at for sure.

Thanks Hood,


Just to add a bit. For any machine being driven by Size 23 motors, the G540 is arguably the best value for money.  Coupled with a 48Vdc  7A switch mode power supply, you have a complete 4 axis setup.

The G540 contains 4 separate G250 stepper drives that are user replaceable. If one blows it is easily changed. I've been using a G540 since they were first released, some 2 years ago without any issues.

Cheers,

Peter.

Technoligy changes so fast 3 years ago I designed and built my machine. Now I am ready to start building a few more machines differnt type and smaller The other machine used 680 and 450 oz. inch motors. The head was a 100 pounds moving gantry. Now the new machines will use much smaller motors and use a moving pallet on a sprocket, roller arangment  Much smaller foot print and for a differnt use. But it will use use gekos. I was going to use the same arangment as before but this controller looks better and would be a couple of hundred cheaper. I was also looking at puting a computer board into the control panel. leave the main computer to run more than one machine.
