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

[steeve (steve j)]

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 approx 21 cm circumference, used in the rotary setup (c. 70mm dia). If i “position laser” at y=5mm then reposition at y=205mm the spindle rotates to the order of 550 to 600 degrees.
Can lightburn have instigated a new/corrupt “conversion figure” to change from circumference to steps?
I have tried playing with the “stated circumference” to try and compensate on the urgent job that did not work either (and I do NOT want to stay with that). It is as if it has a permanently fixed circumference to step ratio, rather like a roller drive (I have changed to roller and back to chuck also rotary to cartesian to rotary). As stated at the top it used to work.

Any ideas before I block off the disk space currently used by lightburn and then try to reinstall?

Hi Steve, which ORR unit are you using? 1 or 2?

There are some firmware commands to send pre-use according to their video here: Installation and Use of Ortur Y-axis Rotary Chuck - YouTube

With that said, if you were using it fine before but now you’re having issues, something has changed. It may sound odd, but are you in inch mode? Ive seen a couple reports of odd behaviour with that that we’re investigating at the moment. The fact that you get an as-expected 1 rotation from the test feature.

Thanks for taking an interest. I own an ORR2 but am NOT using it.
I have been using the Ortur YRC1 (Y axis Rotary Chuck ?)

[steeve (steve j)]

Just to say that I had looked at the Ortur and some 3rd party videos prior posting. The Ortur video suggests 96 mm/rev but they are using the more recent OM3. 120 seemed to work over the last month. I will check the imperial~metric aspect bit I would have though that would provide a 250% variation and really become obvious on the x axis (which is behaving, as is the cartesian y)

[steeve (steve j)]

I have now reinstalled Lightburn, same symptoms. I do wonder if it has somehow become stuck in the “roller drive” mode, which would explain the same result regardless of declared “diameter”.

[Colin (Colin Worobetz)]

If you switch out of rotary mode, is the movement in X and Y to scale as expected?

Please type ‘$$’ + Enter into the Console, and paste the results here for us to inspect.

[steeve (steve j)]

yes, when switched back to cartesian it behaved, default metric operation
