Input/Output - Spindle

This group of settings configures output pins for Spindle and Coolant control and spindle synchronization.

Assigns output pin for spindle clockwise control (g-code commands M3/M5) . Digital output pin is selected trough drop down menu.

Assigns output pin for spindle counter clockwise control (g-code commands M4/M5). Digital output pin is selected trough drop down menu.

Assigns output pin for spindle ON/OFF control (g-code commands M3/M5) . Digital output pin is selected trough drop down menu.

Assigns output pin for spindle direction control (g-code commands M4/M5). Digital output pin is selected trough drop down menu.

Dedicated controller output pins can generate Frequency, PWM and RC servo signal.

Inserted value is min value of spindle RPM. Meaning, when g-code e.g. S1200 will be executed in program, controller speed pin will be generating min value of either output frequency, PWM modulated signal or RC Servo signal.

Inserted value is max value of spindle RPM. Meaning, when g-code e.g. S24000 will be executed in program, controller speed pin will be generating max value of either output frequency, PWM modulated signal or RC Servo signal.

Delay period allowing the spindle to ramp up to its RPM value. This value is in seconds.

Delay period allowing the spindle to stop rotating. This value is in seconds.

When enabled, Speed Pin will generate frequency signal. Freq. Min, Freq. Max and Step Width parameters will be considered.

Frequency value of generated speed signal when S gcode Min. value is used in program.

Frequency value of generated speed signal when S gcode Max. value is used in program.

Entered value is pulse width of generated speed signal. When set at 0, duty cycle of generated speed signal is at 50%.

When enabled, Speed Pin will generate PWM signal.

Value of PWM base frequency.

When enabled, Speed Pin will generate RC Servo signal. RC Servo Lo-Hi parameters will be considered.

Minimum value of RC servo speed range.

Maximum value of RC servo speed range

These settings apply to encoder connected to CTRL pins: EN4A and EN4B for Mk3 controller and ENC A and ENC B for Mk3/4 controller.

PPR value of your encoder. We recommend 100 PPR encoder for best results.

Invert: Inverts encoder inputs

Reverse: Enables reverse direction of encoder.

Number of index signals per one revolution of encoder.

Invert: Inverts Index input

Debounce time value for encoder signals.

Enables synchronisation

As Set: Value of spindle speed (RPM) used for synchronisation move speed will be the one using current spindle speed value.

From Index: Value of spindle speed (RPM) used for synchronisation move speed will be calculated using Index signal.

From Encoder: Value of spindle speed (RPM) used for synchronisation move speed will be calculated using Encoder signals.

Sync Signal: If None is enabled, then machine does not use neither, index signal or encoder signals for spindle synchronisation. Sync signal is not used.

From Index: Index signal will be used for determining starting point of first synchronisation move, e.g. threading cycle.

From encoder: Encoder signals will be used for determining starting point of first synchronisation move, e.g. threading cycle.
