Rotary Setup Problems - Stuck in Roller Mode?

[jbl (Jace)]

Good evening and thanks for reading my post.

I have been using my Orthur Rotary Chuck for a few weeks now with no problems until recently. It seems to me the software is stuck in the mode of thinking it has a roller attached instead of the chuck. No matter the value I enter into the circumference, nothing changes when I close out of rotary setup and jog Y axis. Steve seems to have the same issue in the link below.

Weird change in operation of rotary chuck (over rotates) Ortur

Hi, I was this morning using the Ortur rotary chuck with a Lasermaster 2, all going well. On restart this afternoon, with same files etc, it over-rotated (perhaps by 60%). Rotary “settings” seemed fine. Powered down and waited a full minute before rebooting the pc and laser, same problem. Plugged in the cartesian y axis, behaved normally (so presumably the ortur controller is sending the correct pulses). Tried the rotary set up “test”, the usual “120mm/rev” produced one rotation. Workpiece is a…

When testing in the rotary settings, it makes 1 full rotation as it should. Close settings, jog Y same amount as circumference, and it rotates 2.5 times. Aufero Laser 2 with Orthur Rotary Chuck. Running latest version of Lightburn. Have tried on two different computers with the same problem. Here is a video.

Any advice is appreciated as I am at my wits end with this one. Thank you.
