MACH3 & Servos
« on: April 13, 2006, 10:37:24 AM »
Still relatively new to this whole Mach3 thing, but is Mach3 suitable for controlling Servo motors?

Very cool! Looks like a really good resource, thanks for the Link! I see near the bottom a couple of Servo based systems so I guess that must be a yes? I assume, that it is more a factor of the motor controllers than the motors themselves...is that the way of it? I am not sure how servos systems work as I have only really worked with the Stepper systems.

Hi,

I use servos on my lathe, the main difference is that you also have encoder feed back so the system is more accurate, as far as setting it up its almost the same as steppers.

Thats all I needed to know thank you! I may be retrofitting an older CNC for a friend but I was unsure of the motor system because it is currently servo... and I dont think he wanted the extra cost re-fitting thye system with new motors.

Thanks for thie info!

Hi there

I am currently using Panasonic servos for a lathe, but they accept step and dir inputs. They take care of themselves and call an error if they lose position. It is also possible to use a converter board which takes step and dir inputs and converts to +-10v to drive older analogue servo systems. See Skyko technologies.
