Laser Position not compatible with A-axis rotary

[pacheth (Thierry)]

Please note this “issue” is specific to rotary using an independent A-axis (NEJE Max 4).
The move commands are OK: Y coordinate is actually moving the Y axis.
Engraving is OK as the laser is converting Y axis coordinates in A-axis (rotary) ones.
But…
The “Laser Position” icon in the tool bar is dangerous. Because it actually triggers a Y axis movement instead of making the roller… rolling
For me, it can be considered as a dangerous bug or mis-feature as I can’t use this tool for drawing position check on the roller.

The “Laser Position” icon in the tool bar

I am having trouble finding this. Can you provide a screen capture of the control you are talking about?

Indeed, a picture is easier for understanding. Here it is:

Learned something new today, never used that feature.

Having said that, how is the Aaxis displayed in the workspace? Why would you expect the control to move the Aaxis instead of the Yaxis, especially if the Yaxis is still enabled?

I did not see the workspace axis labels change. This would make me believe axis controls dependent on the workspace would conform to the workspace labels.

Considering Lightburn is a 2-axis application, I think you have the makings of a good feature request. I ran a small code generation test and this is my result:

I believe you have the makings of a good Feature Request…This is your discovery, so submit it.
If the rotary is enabled and a non-Yaxis motion is selected, update the workspace graph labeling and inhibit any Yaxis control.
