MDF Rose Engine Lathe 2.0

Enabled

Indicates that the selected stepper motor is enabled even when not in use. Touch this to change it to Disabled.

The More screen can be used to set this to be continuously Disabled or Enabled. These buttons temporarily override that configuration setting.

Key Note:When using DM542T stepper motor drivers, this needs to be Enabled (especially for work using indexing), otherwise the position will be lost and the movement will not be predictable.

Disabled

Indicates that the selected stepper motor is only enabled when in use, and then disabled. Touch this to change it to Enabled.

Used to initiate movement in the indicated direction on an axis. Movement continues until Stop is pushed.

Used to stop the motion of the stepper motor.

Used to return the spindle or the selected axis to the start point of the previous operation.

When using this function, Be sure to stop and retract the cutter from the cut first. The return path does not always follow the same path as the initial cut. (Backlash and other factors come into play here.)

The speed of the return action is set in the Preferences | Returns screen.

Used to initiate movement in the indicated direction on an axis. Movement continues until Stop is pushed.

Config

Touch Config on the screen image above to see the details for this screen.

This is used to display or edit the configuration settings for the MaxSpeed and the Acceleration for the respective stepper motors.

Greek Key Pattern Screen

Purpose: This screen allows the user to create Greek Key or Meander patterns. Patterns are created by moving the spindle, or one of two axes individually.

Greek Key cutter movement paths are available for you to see how the path taken.

Axial

Used to create a pattern axially

Radial

Used to create a pattern radially (circumferentially)

Built-in Patterns

Segments		Pattern
Wide	Tall	Pattern
2	3	2a
2	6	2b
3	4	3a
3	8	3b
4	8	4a
4	13	4b

Count
Count

The value with a yellow background determines the actual number of patterns to create. Setting it less than the Patterns/360 value will leave a space at the end of the pattern. Setting it larger will recut the same pattern. This is useful when you want to cut a pattern deeper.

The value with a gray backround shows the current count as the sequence is run. (This was introduced in version 24.)

Length

This specifies the length of the shortest Z or X axis segment. Each pattern will have segments which are a multiple of the shortest segment.

Patterns / 360

This specifies how many individual patterns will fit in 360 degree rotation of the spindle. This controls the length of the shortest spindle segment.

B Radius

B Radius is the distance from the center of rotation to the cutter. This field is only visible when moving on the B axis and radial movement is selected.

Speed

The controls on the left and right side of the screen are for controlling the respective stepper motor's speed and acceleration.

To change the Max Speed, touch the number, and you will be presented with the Number Pad Screen.

The slider is a red bar that can be moved up to increase the speed, or down to decrease it.

Want to understand this better? More details about the stepper motor speeds are on this page.

Acceleration

The bottom number (15001 on the left; 4300 on the right) is the acceleration for the stepper motor.

To change this value, touch the number, and you will be presented with the Number Pad Screen.

Limit Switches

Limit switches cannot be used with this function.

Specific Axis Notes

Axis	Comments
Spindle	Movement continues until the identified movement distance is completed, or the stop button (shown to the right) is used.
Z	Movement on this axis is the same as for the spindle.
X	Movement on this axis is the same as for the spindle.
B	The fields on this screen are used with the fields and settings on the B Axis Configuration screen to calculate how long to run the stepper motor to achieve the desired rotation. Movement on this axis is the same as for the spindle.
