In order to utilize the optional SPINDLE and COOLANT controls in the Techno CNC Interface, the Spindle must be connected to the power box, and the Coolant must be connected to the controller card.

Spindle

If your Spindle is connected, power is controlled by clicking the radio button corresponding to On, Off or Auto under Spindle. If you set the Spindle to Auto, power to the Spindle will go on and off as specified in your program(or GCODE file). Whenever the spindle is turned On, a delay window will pop up notifying you that the program has stopped running for a preset delayed amount of time (see the Speeds tab in the Setup window) allowing the spindle motor to ramp up to speed.

If you need to adjust the Spindle RPM rate, you can do this in the Speeds tab in Setup, OR you can perform a shortcut to changing the Spindle RPM by holding down for an extended mouse-click on the ON radio button (the program will pause during this operation). The Spindle RPM mini-window will appear.

Coolant

If your Coolant is connected, its release is controlled by clicking the radio button corresponding to On, Off or Auto under Coolant. If you set it to Auto, Coolant will be released as specified in your program.
