4 Assembly and Operation
Assembly
Please refer to the manual of your milling / engraving machine for assembly instructions. Pay attention to the required
cable lengths of the supply lines to all movable elements. If possible, use additional fabric hoses to protect the supply
lines. Mounting material is not included in the package of the control module.
Power supply
The control module requires a 24VDC supply for operation. The required current depends on the connected CNC
milling / engraving machine. Usually a DC power supply with 24V rated at 5A is sufficient.
Operation
Connect up to three stepper motors to the terminals labeled "X-MOTOR", "Y-MOTOR" and "Z-MOTOR".
A spindle motor is connected to the 2-pole "SPINDLE" connection. Pay attention to the
polarity. The plus pole is usually marked red whilst the minus pole is marked black.
