Axis Selection

Key Note: The configuration program cannot be run when the Rose Engine Butler program is running. It is designed so that you configure the way Rose Engine Butler works, then run the system.

Lathe Axes

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

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 channel (i.e., which plug) on the boxes is used for each axis. The only limitation is that Sp1 cannot be selected when Sp0 is not also selected.

The Rose Engine Butler handles up to 10 channels - 6 on the base box and 4 more on the optional expansion box (see Base Box and Expansion Box below) - and any of the following can be assigned to them:

• Two Spindles
  • Main Spindle
  • Rosette Phaser/Multiplier
• 8 traditional axes
  • Linear axes: X, Z, U, V, or W (Y cannot be used on LinuxCNC when configured as a lathe)
  • Angular / Rotary axes: A, B, or C

Spindles

The two spindles, Sp0 and Sp1, are used when you use the options on the main panel:

• Run Operation (to run the spindles in forward or reverse), or
• Indexing the spindles

If those motors are needed for synchronized movement with other axes,

1. This is done via a gCode program, and
2. The spindles will need to use one of the rotary/angular axes (A, B, or C) for their motion.

Base Box and Expansion Box

Each plug's number matches its channel number. On the Axis Selection screen, the base box's channels are on the left and the expansion box's on the right, each laid out the way the plugs are on the box (Top and Bottom rows). The E-stop button and signal tower plug into the base box only.

Connected - tick the Connected box next to "Expansion Box" only if the expansion box is plugged in.

• With it ticked, LinuxCNC looks for the expansion box when it starts. If it can't find it, LinuxCNC will fail to start. If that happens, untick Connected and start Rose Engine Butler again.
• Turn on both boxes before starting Rose Engine Butler.
• Ticking or unticking Connected takes effect the next time Rose Engine Butler starts.

Without the expansion box its channels (and limit jacks 4 to 6) are greyed out, and the axes assigned to them can't be used. They keep their assignments, ready for when an expansion box is connected. To use one of those axes, choose it on a base box channel - the two swap, so the axis that was on that base box channel moves to the expansion box channel. For example, if Sp0 is on channel 06 and W is on channel 04, choosing Sp0 for channel 04 puts W on channel 06.

Impact of Any Changes

Axis Assignments on Base Box

Axis Assignments with Expansion Box

Once the changes are saved and Rose Engine Butler is restarted, 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 (an example is to the right)
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 Axis Assignments table displayed at the bottom of the right side panel, which shows the axis on each channel. The expansion box's channels are only shown when it is connected. Any axes not assigned to a channel in use are grayed out and not usable by the operator.

Running the Rose Engine Butler Settings Program
