I keep getting “Rotary setting update failed” in the 1.7.08 version of LightBurn. I have a Blade 50W IR laser that uses a Rodiu controller. I have to click the enable rotary button twice to get it to turn on. When in the set-up drop-down, after inputting my steps per rotation and circumference and hitting OK, it turns off the rotary enable button and reverts back to the roller setting.
Please send a link to the seller’s (or manufacturer’s) product page for your laser.
Go to Edit>Get Controller Info - what do you see? please send a screenshot.
Most likely a 50W co2 using a Ruida controller… although Rodiu is pretty close. I suggest he confirm the controller type/model.
I tried to find a similar machine, so as @NicholasL requested, a link to your machines vendor would allow us to see something very similar to what you have.
You can look inside the electronics cabinet and see what kind of controller is there. If you don’t know how to locate it, post a photo and we’ll try and help out. Mine is a Ruida 6442G, white box bottom left.
Hopefully we’ll get something useful from Get Controller Info.
Mine identifies the firmware…

That “Rotary setting update failed” thing you’re seeing in LightBurn 1.7.08? Yeah, that’s been driving people nuts lately. Especially with Ruida controllers—it’s like they’ve got a mind of their own. You’ve got a Blade 50W IR with a Rodiu controller, which is basically Ruida with a fancy badge. Same rules apply.
The reason you’re having to click that “Enable Rotary” button twice and it keeps flipping back to roller? That’s LightBurn thinking it’s smarter than it is—it’s not fully writing the settings to the controller, or the controller’s not responding the way it should.
Here’s what I’d try:
- First off, don’t just hit OK after entering your steps and diameter. Try this:
- Go into Rotary Setup
- Enter your steps per rotation and object diameter
- Hit “Tab” after each field so it really confirms the entry
- Then hit OK
- Immediately go back in and make sure nothing changed
- If it flips off rotary after you click OK, turn it back on manually—but keep that screen open and try again. Sometimes it takes two passes to “stick” depending on how fast the controller talks back.
- Also, update to LightBurn 1.7.10 or newer if you haven’t yet. 1.7.08 had a few buggy bits with rotary settings on Ruida clones. They’ve cleaned that up a bit in the latest builds.
Worst case, if it keeps reverting to roller, just manually turn rotary mode on from the machine control panel, and ignore LightBurn’s button altogether. It’ll still work—you just lose the convenience of having it all synced.
Do you have a link to this controller, I tried to find it on your first post.
Yep—the Rodiu controller is basically a rebranded or clone variant of a Ruida controller. So anything weird that happens with Ruida systems (like rotary settings not sticking, inconsistent UI feedback, or needing extra steps to confirm settings) tends to happen with Rodiu as well.
They use the same backend logic for rotary control, which means when you hit that “Enable Rotary” toggle in LightBurn and it flips back or gives you the “update failed” message, it’s not always your fault—it’s the controller and LightBurn not fully syncing up.
If LightBurn doesn’t push the setting through, your best bet is:
- Confirm the values by hitting
Tabafter entering them - Hit OK
- Reopen the rotary window to make sure it saved
- If not, manually turn rotary on from the machine’s control panel, and ignore LightBurn’s rotary toggle altogether. It still works.
Newer versions of LightBurn (like 1.7.10 and above) have better support for these kinds of controller quirks.
I can’t find a word about it in my Internet searches. Do you have any kind of link of where to buy or get information on it?
I only lasted less than two weeks using usb, then just went with a direct connection from the PC to the Ruida. I have never gotten the error you speak of.
Are you using USB or Ethernet, does it matter?
I know the UDP/IP protocol limits error reporting, but I don’t know at what level of information Lightburn can actually retrieve from the Ruida.
