MDF Rose Engine Lathe 2.0
Control System for Multiple Stepper Motors
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.

Also resets any Enabled stepper motors to Disabled.

Enabled
Disabled

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.
One Screen
Axis Movement

Touch Spindle on the screen image to the right to see the details for the spindle control.
Purpose: This screen allows for independent movement along of a single axis. It is useful for higher or lower speed movement than the Main Screen (e.g., quickly moving the cutter to one end of the linear slide).

This selects the axis of movement. In this case, the X axis' motion is performed using the buttons at the bottom of the screen.

Only one axis of movement may be selected at a time.

 
These axes of movement are not selected.

Enabled
Enabling a stepper motor locks it into place, preventing motion along the relevant axis. One use for this would be to lock the spindle whilst changing a rosette. Or in this case, the Z axis movement is locked whilst the cutter is moved along the X axis.

The stepper motor on a given axis may be enabled even if that is not the axis of movement.

When the Stop button is selected, the stepper motor on this axis is reset to be disabled.

More than one stepper motor may be enabled at a time.

 
Disabled
This stepper motor is disabled, allowing for manual adjustment (e.g., manually rotating the spindle).

Speed The controls on the 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 (4000) 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 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.
