How to resolve the "Rotate mode disables absolute cs" message on the HMI when running a rotary job in LightBurn.

Applies toAll machinesTopicGeneral

If you get a "Rotate mode disables absolute cs" message on the HMI while using the rotary, that means that you tried to start a Rotary Job using absolute coordinates which is not permissible.

Go back into Lightburn and set the Start from to "User Origin" and re-send the job and overwrite the file on the machine.

Lightburn will automatically switch the "Start From" to Absolute coordinates when using the Camera or features like Print and Cut.

What to check if the message appears but no Rotary is plugged in and Enable Rotary is Off

The ground signal from the TL timer board could potentially be telling the Ruida Controller that Rotary is plugged in when it is really not. To test this, unplug the connector shown below and try to run the job.
