Settings

long press on MENU to enter settings, navigate with UP/DOWN, change values with B+/B-, and exit with MENU to save.

Position Max

The maximum position allowed to move forward, away from the home position (in current units).

Applies only when the home position is known.

Bounce

Select the bouncing behavior, applies only when home position is known.

  • None will not bounce at all
  • Backward will bounce when moving backward at zero position.
  • Forward will bounce when moving backward at position max (see setting Position Max).
  • Both (default): Backward and Forward behavior combined.

Steps per Revolution

Total number of steps per revolution (including microstepping) for stepper motors.

Units per Revolution

  • Metric (linear): millimeters of linear travel per revolution.
  • Imperial (linear): inches of linear travel, per revolution.
  • Degrees (rorary): degrees of rotation per revolution.

In rotary mode it is fixed at 360 degrees per revolution (unit = 1 degree).

Maximum Speed

The maximum allowable speed is bounded by the maximum pulse generation frequency.

(See stepper configuration section for details).

Acceleration

Backlash

The backlash to apply in selected units when changing direction of movement/rotation

Backlash Speed

Select between Current and Maximum.

  • Current use current speed as configured by the user controlled potentiometer.
  • Maximum use maximum speed as configured by the maximum-speed setting.

Homing Speed

The speed to use while searching for home position.

(See limits homing section for details).

Homing Direction

Set the homing direction to either Forward or Backward.

Backoff Distance

The distance to move back from the homing switch after it is triggered.

Enable Pin

Set if the enable pin should be active high or active low.

Direction Pin

Set if the direction pin should be active high or active low.

Limit Pin

Set the behavior of the limit switch pin. The external limit is triggered:

  • Falling Edge on a transition from a logic high (5 Volts) to logic low (0 Volts).
  • Rising Edge on a transition from a logic low (0 Volts) to logic high (5 Volts).

Contrast

Set the display contrast.

Units

Set the units to use. Changing the device units will reset all the unit related settings to their defaults and additionally reset the device status, e.g set position to zero and forget the home position

  • Millimeters (metric, linear mode):

    • Steps: 0.01 mm, 0.01 mm, 0.1 mm, 0.5 mm and 1.0 mm.

  • Inches (imperial, linear mode):

    • Steps: 0.001 in, 0.005 in, 0.01 in, 0.05 in and 0.1 in.

  • Degrees (rotary mode):

  • Min step 360/720 deg (1 step is 1/2 degree).
  • Max step360/1 deg (1 step is 360 degrees)

Note

Requires a long press on the B type buttons to confirm the action.

Warning

Changing units restore all the factory default settings.
