    Just finished a Shynix 1050 with the latest version sparks pro board. Im running the high torque 345 oz. motors and using a ATX 450 watt power supply. I can actually stop the motors when running with just lightly pinching the screw to motor couplers. Any ideas ? Thanks,Les

    Most people's first assumption is going to be your current limiting... You got that set right? (I'm not familiar with the specific board)

    Its a sparks cncprov all in one board. Comes with the openbuilds shynix router kit. Don't think it has any limiting options but Im not an electronics pro. Could it be the atx power supply im using?

    You should be using at least a 24V power supply. Additionally, have you adjusted the current settings (potentiometers) on the xPro board?

    To get full power out of the high torque steppers though you should be using proper drivers. The xPro board cannot supply the full 3 amps they require.

    I agree with Rick, you need higher voltage power supply. I would also use higher amperage drivers like he listed. This is the guide for your xpro board. It tells how to set the current and other troubleshooting. Spark-Concepts/xPRO

    Also make sure your couplers are actually attached firmly. Your electronic settings don't matter if the motor/lead is just spinning in the coupler.
