MDF Rose Engine Lathe 2.0
Control System for Multiple Stepper Motors
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 turn the spindle counter-clockwise. On a traditional lathe, this is considered forward.

Used to turn the spindle clockwise. On a traditional lathe, this is considered reverse. To change the direction of the spindle, you must stop it first. You cannot directly swap between clockwise and counter-clockwise.

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.

Used to move the item on the respective axis (e.g., a cutting frame) in the negative direction. If this is the Z axis, that is to the left; for the X, it is towards the back of the lathe.

Used to move the item on the respective axis (e.g., a cutting frame) in the positive direction. If this is the Z axis, that is to the right; for the X, it is towards the front of the lathe.

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.
Main Screen

Purpose: This screen allows for direct control of

  • the spindle's speed and direction, and
  • the axis speed and direction for one other, independent stepper motor.

This screen is typically used for continuous spindle and/or continuous axis motion (turning or facing cuts, continuous rose engine patterns on cylindrical or face surfaces., etc.).


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 (4001 on the left; 5000 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 & EStop

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.)

If the EStop is engaged when using this function, all the movement buttons will turn red.

To reset:

  1. Ensure the EStop switch is not closed, and
  2. Touch one of the stop buttons.

Specific Axis Notes

Axis Comments
Spindle
Movement continues until the stop button (shown to the right) is used, or a limit switch is engaged.

Limit switches will only stop rotation of the spindle if Stop Spindle with Axis is selected on the Limit Switches Configuration Screen.
Z Movement continues until the stop button (shown above) is used, or a limit switch is engaged (or it crashes).
X Movement on this axis is the same as for the Z axis.
B Movement on this axis is the same as for the Z axis.
