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.

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.

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

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 the identified 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 the identified 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.

Program Screen

Purpose: This screen allows the user to perform activities based on the patterns outlined in a file. This allows for automating process steps to create an object, removing the amount of interaction required to achieve the desired results.

Details on the File Information and File Identifiers helps explain how the file is created to use this function. Patterns are created by the commands in the file which move the spindle, or one of two axes individually.

Examples are on the starting page for this help, under the heading of Index of Activities and Other Key Information.

Radial

Used to create a pattern radially (circumferentially)

Axial

Used to create a pattern axially

Segments

When selected, values in the file are interpreted as a multiplier of the "Length" for the Z, X, and B axes and as a multiplier of the calculated segment size for the spindle. Floating point numbers are valid.

Actual

When selected, values in the file are used as the length of the move. Floating point numbers are valid.

B Radius

This is used when using a Spherical Slide, and is a rotation about the Y axis.

This is a measure from the axis of rotation to the tip of the cutter.

The number entered has no specific units of measure, but is used to calculate the circumference of the circle representing the movement around the Y axis. That value gets used to set the movement according to the file's specified amount of movement.

This was introduced in v16. If your system is a prior version, it will not display this option.

Count
Count

This 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.)

Patterns / 360

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

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. This can be a floating point number.

Command

This is the command from the file which is currently executing. This information, along with the next two items, are very useful when running a new design. It helps the user to monitor the progress as it happens. If something does not work as desired, then this shows you where the process is at that time so that it is easer know where to change the file as necessary.

Segment

This is the segment from the file which is currently executing.

Line #

This is the line # from the file which is currently executing.

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 can be used with this function. The pins used for this are configured on the Limit Switches Configuration Screen. (More information about the implementation of limit switches is on that page.)

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.
