Have you seen this?

That looks to me like a very flimsy frame.

Educate us a bit, Dick. Is one superior to the other?

[DickB]

Depends on the use. In our useage I would say servos are better suited. Stepper motors are slower. They lose torque the faster they spin, so they generally need to move slower. Steppers turn in increments or steps, hence the name. A stepper motor controller sequences current through the motor's coils and the motor turns in fixed increments. There's generally no secondary feedback to indicate how far the motor has actually turned, so stepper systems are generally cheaper. Servos do not lose a lot of torque at speed, so they are generally faster. Ours use optical encoders for feedback, so unless something is broken or dirty the controller knows exactly how far the motor has turned.

Might want to wait a bit. I believe they are upgrading the Gantry to a sturdier version.

I think Jason from the forum here sells them

No one is really selling those yet ... there will be one at the Cnc Jamboree. Come check it out. www.CncJamboree.com
