The ballnut stop blocks replace the original brass feed nuts. Hardened, but cut easily with a carbide insert. The ballscrews must be turned down to match the prints. long for the X and Y) are tapped 10-32 for the motors.

Holes must be drilled and tapped 1/4-20 on the mating surfaces of the mill. To mount the steppers, I made aluminum mounting brackets. This would provide a bit more speed but at more $.

(4) 381 oz/in motors and 48 Volt power supply. Note: Kelinginc now have kits with the Geckodrive G540 4 Axis driver, The best option is to use the G540 package with 381 oz/in motors listed in the X2 Electronics. Leave it be for now, it should make life a little easier for the motor. Out it wasn't necessary as the Z motor has plenty of power now to raise the head without it. I have a counter balance installed as described here. I'm running at 1/2 step for the X and Y axis and full step for the Z axis. I get up to 130 IPM for the X, 65 IPM for the Y andĤ0 IPM for the Z Axis. The bipolar driver only needs 4 wires so I used some 16 AWG speaker wire. You can also find some nice power supplies at Circuit Specialist. Is recommended (request a 381 oz/in for the Z axis). Nema 23, Option 2 with the 270 oz/in motors
GECKO G540 MICROSTEP DRIVERS
Power supply, drivers and a breakout board. Keling also has complete kits with motors, It has over voltage and shortĬircuit protection built in. It is a singleĪxis bipolar driver rated up to 40 Volts and 1/64 microstepping. I originally used a 3-Axis driver from but the performance was not up toĮxpectations. There are many types to choose from and many companies sell kits in various configurations. To begin, I had to decide on the Stepper motors and Controller.
