Wiring Schemes
The Rose Engine Butler system cable wiring schemes are outlined on this page.
Stepper Motors
Cable Sizing
The cable between the Rose Engine Butler system and your stepper motor should be a 4-conductor cable.
The wires in the cable should be a minimum of 20 AWG (gauge). This will ensure the wire can easily handle the amperage for the NEMA 23 stepper motors.
Connector
A GX-16/4 connector is used to connect stepper motors to the Rose Engine Butler system.
Wiring the Motors
| GX-16 Pin | Stepper Motor | Comments | |
| Stepper Online Wire Color | Purpose | ||
| 1 | Black | A+ | If the motor is driving the spindle in the wrong direction, there are two options:
|
| 2 | Green | A- | |
| 3 | Red | B+ | |
| 4 | Blue | B- | |
Limit Switches
Cable Sizing
The cable between the Rose Engine Butler system and your limit switch should be a 2-conductor cable.
The wires in the cable should be a minimum of (TBD) AWG (gauge).
Connector
A GX-12/2 connector is used to connect limit switches to the Rose Engine Butler system.
Wiring the Switches
| GX-12 Pin | Wire Color | Purpose |
| 1 | Red | +V |
| 2 | Black | GND |
E-stop Switch
Cable Sizing
The cable between the Rose Engine Butler system and your limit switch should be a 2-conductor cable.
The wires in the cable should be a minimum of (TBD) AWG (gauge).
Connector
A GX-16/2 connector is used to connect this switch to the Rose Engine Butler system.
Wiring the Switch
| GX-16 Pin | Wire Color | Purpose |
| 1 | Red | +V |
| 2 | Black | GND |
Signal Tower
Cable Sizing
The cable between the Rose Engine Butler system and your signal tower indicator light should be a 4-conductor cable.
The wires in the cable should be a minimum of (TBD) AWG (gauge).
Connector
A GX-12/4 connector is used to connect this switch to the Rose Engine Butler system.
Wiring the Light
| GX-12 Pin | Wire Color | Purpose |
| 1 | Green | +V |
| 2 | Red | +V |
| 3 | Blue | (unused at this time) |
| 4 | Black | Common GND |
