ℛ Settings

This tab has multiple sub-tabs, and they are used to provide the user with the ability to maintain the values needed for using the Rose Engine Butler system.

Axis Selection

The Rose Engine Butler handles 8 axes:

• Two Spindles
  • Main Spindle
  • Rosesette Phaser/Multiplier
• 6 configurable axes

On this screen, you select which axes you want to use. You must select from the standardized ^① options:

Lathe Axes

Whilst these are the traditional interpretations of those axes, there is nothing particularly critical about them except that some are linear, and others rotary. So, if you need to implement a device which has 3 axes rotating around the spindle axis, you can use A, B, & C to do that -- you'll just have to keep everything straight.

Additionally, you can select which plugs on the box are used for each axis. The two for the spindles are locked, but the other 6 are configurable.

Impact of Any Changes

Once the changes are made, and the system rebooted, changes made to this screen:

1. Set the way LinuxCNC interacts with the plugs on the system (via the channel assignments)
2. Update the axes displayed on the right side panel
3. Set the options available for the axes on the right side panel (linear axes have different options than angular/rotary axes).
4. Update the table displayed at the bottom of the right side panel.

Notes:

1. EIA RS-267-B, AIA NAS-938, & ISO/R 841

Axis Scaling

Set the desired scale values for the spindles and each axis.

The comments on the right side of the screen outline some guidance, and best practices, for setting these. There is more, in-depth information at Axis Settings for a Device.

The buttons at the bottom of the screen are:

This is used to make a backup of all the current values you have entered. The data are saved to the default file.

This is used to save all the settings to a separate file. The usefulness of this is where you have made a number of changes and want to re-load them later.

This is used to save a subset of the system settings. For each axis selected, you will need to select a device name.

This is used to load the settings saved via one of the 3 options above. If the file is a portion of the settings, only those are loaded (e.g., if you want to load only the settings for a curvilinear slide).

Takes you to the page in this user manual which helps you determine the axis settings for a device.

Notes:

1. There are fields for setting the scales for all axes, including the ones not being currently used. The only ones used are for the axes being used.
2. This panel is bigger than the screen. To scroll, you will need to use your mouse to move the bar on the right side of this panel. (The Glade system used by LinuxCNC does not accommodate the use of the mouse wheel.)

Stepper Motor Tuning

This is used to set the values for each spindle and axis. The tuning already set worked during testing, and the user is cautioned from making significant changes. If you do so, we also recommend you record the starting values (so you can restore them if necessary).

For the spindles (Sp0 & Sp1), there are both position and velocity values.

• The position values are used when indexing the spindles using the Indexing buttons or the M19 gcode.
• The velocity values are used when running the spindles via the Run Operation buttons, or when using M3 or M4 gcodes.

Notes:

1. There are fields for setting the scales for all axes, including the ones not being currently used. The only ones used are for the axes being used.
2. More information is available at:
   • LinuxCNC PID Component Reference
   • PID Controller (Wikipedia)
3. These get saved when the program is exited, or when one of the Save Settings buttons is used on the Axis Scaling tab.
4. This panel is bigger than the screen. To scroll, you will need to use your mouse to move the bar on the right side of this panel. (The Glade system used by LinuxCNC does not accommodate the use of the mouse wheel.)

Other Tuning

Use this to set the maximum, default, and minimum jogging speeds for

• Linear axes: Jog speed for the X, Z, U, V, & W axes.
• Rotary (Angular) axis: Jog speed for the A, B, & C axes.

These are used when moving under Manual Control [F3].

General

There are some general values which get set here:

1. The measurement system to be used (Imperial or Metric)
2. Device names to be used for the selection fields. You enter them as one device name per line.
