There are quite a few old threads, now closed, in this forum about using rotary control with the Ruida 6445G but none of them come to any real conclusion. Apologies for starring a new thread but I think it’s the only option now those are all closed.
It seems to me that the current situation is:
V15.01.22 of the 6445 firmware (which is what you get if you buy a new unit from Cloudray) has at least some support for rotary on the U axis. The motion control buttons operate this correctly for example.
However trying to use this through Lightburn doesn’t work. No matter what you try with the rotary settings nothing ends up running correctly. Either the laser won’t fire, the wrong motors run, or it fails with an error. One user from LightObject reported getting it to work, but it looks like nobody else (including me) has so far been able to duplicate their success.
To add insult to injury it seems that the previous ‘swap Y with rotary’ method no longer works either! Using the Lightburn rotary settings changes the Ruida’s response such that the Y channel no longer behaves as it did when in rotary mode. ( I assume this is deliberate and the U channel is now supposed to do the job.)
The only way I can get rotary to work with Lightburn and the 6445G with 15.01.22 is to swap Y and rotary, but not tell anyone. That is, don’t enable rotary in Lightburn or in the DSP and instead do the math yourself to scale the y axis appropriately. This works, but is very 20th century.
I understand this may be out of Lightburn’s control but I request that we establish that as a fact before moving on. Are these changes in the Ruida firmware something that Lightburn can use? If they aren’t, then, at least in my tests, the rotary mode with this model of the Ruida DSP is sadly now of little use.
Lightburn, what say you? If you’ve managed to make it work, please post how you did it.
