VD display scale

[jw4rd]

4-axis XYZA SBP files display correctly with the command 'VD,4,1,1' (A axis in mm), and 'VD,4,1,2' (A axis in deg) displays in inches.

Right now, all the VD command does is set the G20 or G21 and doesn't do anything specific to the A or higher axes.

if ( args[2] !== undefined ) {
var unitType = args[2];
if ( unitType === 0 || unitType === 1 ){
if ( unitType === 0 ){
this.emit_gcode("G20"); // inches
log.debug("Changing units to inch");
}
else {
this.emit_gcode("G21"); // mm
log.debug("Changing units to mm");
}
}
}

As soon as Ryan gets done with the changes to unit values I'll turn on the VD command for A-C.

So, if I do understand, the problem comes from the way the SBP files are translated into G-Code. Can I have the generated G-Code to examine it?

@Alex-Canales I believe the issue is that the rotary axis functionality of the A axis isn't supported in the OpenSBP runtime yet. The VD command only sets mm or inch units. Though, it would be a good idea for you to look at the G-code that would be produced for a file that uses an axis in rotary mode and how it would be displayed. This could be a difficult setup to support in the previewer. @jw4rd do you have a sample g-code file that uses the A axis in rotary mode for Alex to look at?

I have the problem with a three axis SBP file in mm. VD,3,1 is the first line in the file. It runs correctly, but the previewer displays it in inches. The file is 52x53mm, and it displays in the previewer at 52x53"
