Hi to everyone.
My name is Jovan and I am from Portugal. I am new to this forum and in Laser engraving hobby/bussiness. I would really appreceiate if someone could help me with one problem.
Precisely, I have Commarker OmniX, with commarker r5 rotary. Laser works well, i managed to calibrate everything, because there is no .cor file from commarker. Commarker studio is ridiculous piece of software and I bought lightburn pro. Rotary works perfectly in Commarker studio, but in Lightburn I can not manage to use it. I checked, double checked an triple checked all parameters from the manual and from the internet, and all seems to be ok. Precisely, when i press Test buttom, rotary works, but when i start the job it engrave nonsense and moving strangely. I have tried every possible orientation, X and Y axis, everything. In the start i put steps per rotation to 12800, split size 0.1 . Nothing works… I will try to upload link with a short video clip so you can see the behavior and what is happening.
Ifg someone have some idea or possible solution, i would really appreciate it.
Thanks in advance!
P.S. I tried to engrave just a word TEST, nothing more.
It does sound like you’ve covered most of the obvious setup checks already… and the fact that the Test button moves correctly but the job doesn’t is your best most telling find. It suggests the controller is accepting basic motion commands, but not interpreting full rotary job data the same way as might LightBurn expect.
I don’t know for certain how the Commarker firmware handles rotary jobs — it’s not a controller LightBurn officially lists, and I can’t find a confirmed success case. It might be that the driver protocol only partly overlaps with what LightBurn sends, or that a firmware flag or .cor file is missing to tell it how to switch into rotary mode properly, but its not my best area, so hoping someone will chime in.
You might try the Y axis option and a larger split size (maybe 0.5–1 mm just to see if behaviour changes). But if the test move looks clean and the engraving goes wild, I think it’s more of a controller-side limitation than a settings mismatch.
If you do hear anything back from Commarker about LightBurn compatibility, please post it!
P.S. that bit of bamboo looks cool, I’m surprised that the galvo touches it, got to get some of that.
Hi Dominic,
thank you for reply. I already tried to move it on Y axis, and the same thigs happens. For now , no word from ComMarker, I am afraid that they want to promote that junk of software that they have made. In my usb drive i got from them, there is no .cor file or any other configuration like they sent earlier with Omni 1. And as i find on the internet it OmniX is basically Omni 1 with possibility of 3d engraving. Maybe someone can share .cor file for Omni 1 and to try with that ? Or is it a bad idea?
UV doing great marks on bamboo, i am so happy with the results.
Welcome to the world of lasers, @jrhaim
UV sources are fun!
It might be a shot in the dark, but do this quick test: Reverse the rotary direction, and run the same job.
If that wasn’t it, I have a couple of questions:
Does a flat engraving come out correct / not mirrored?
Does it rotate exactly 360 degrees, and back?
This is important. ComMarker should have the exact number of steps per rotation, or you can adjust it yourself, so that clicking the Test button makes exactly one turn.
The way you set it up, you need to select the Y as the Rotary Axis.
Theoretically, you can safely use any .cor file without risk of breaking anything. Lenscorrection files only correct the projection of a specific lens.
The EZCAD zip file from this page contains a “jcz15.cor” file. If you are using the 150mm lens (not the 70mm one), that’s worth a try.
You can load it in the “Laser Tools > Device Settings”.
The Omni X is brand new, and you seem to be one of the first to have it.
I’m curious to hear what you find out!
Hi Aaron,
Thanks for reply. I already try to find it in that commarker download page, but it does not exist there. Also i already tried Reverse direction, same thing…
Flat engravings looks correct, not mirrored, For now everything works as it should except rotary in lightburn. Yesterday i tried several more things. For example i manage to get decent result with putting steps per rotaion to 6400 and even once in 3200. TThe thing is , those results are incosistent. So i can not repeat it. It really looks that it is some kind of incompatibility between Lightburn and OmniX. I will test today is it rotate exactly 360 degrees. I know about axis, and in desperation, i tried even X axis which turns to be wrong :).
If anyone haze that .cor file from Omni 1 i would appriciate if you share it, just to try…
As about OmniX, I am behind my scheduale for jobs i need to do, at a first place because of problems in Lightburn. For me that is the only solution to work normal and stable. Commarker Studio is piece of crap that is unusable for me, but it looks that those people from Commarker purposely lack of lightburn full support to promote mediocre software…
That’s good. If your engraving is not mirrored, the .cor file can’t be the problem here. This lens correction file corrects the scale, trapezoid, bulge and skew values of a particular lens.
A screenshot of the first two tabs of “Laser Tools > Device Settings” could provide insights.
If the results are inconsistent, your rotary might be skipping steps. → Try decreasing the min- and Max speed in the Rotary Setup.
Can you share a screenshot showing your design and the Rotary Settings? Possibly with another video of the outcome, if it is different to the first one.
There are a couple different ports on the back of the Omni X. Based on the pins, it should not be possible to connect the rotary incorrectly, but worth checking.
Hi Aaron,
there is bouth screenshots of device setup. I doblu check hardware connection few days ago and just now, to make my sanity check All is good with hardware side. As I says , I stupid Commarker Studio it works ok…
I will try to change those settings aboiut speed and i will post the video. Thanks!
The device settings mostly match what ComMarker shows in the manual. Apparently, you changed the default values for bulge, skew… Leave them if you are happy, and don’t worry about the .cor file for now. This can’t be the issue here.
One part that’s missing in your Port settings is the “Door Protect”. Set this to 1 as in the manual. (I’m not sure, how that’s supposed to make a difference, and whether you can still close the door when the rotary is in place)
Edit: The Fiber Source is different! They show “RAYCUS” in the manual.
Here are video and screenshots of latest try. Just to notify that I also tried with Reverse rotary swithced off, and the result is the same, rotary uncontrolably spinning and engraving jibberish. Is it possible that something is broken between Lightburn and OmniX or I am crazy? I am also sending a link with the video of test button. Ignore that it is missaligned precisely from the start, but with test button it spins 360 degrees.
It’s not out of the question. We don’t know much about this machine yet.
I just heard that we will soon receive an Omni X to run some tests on!
I feel, you are close to getting it to work though!
It’s hard to tell what the laser is engraving in the video. Increasing the split size to 5mm will likely make it clearer.
What was the result when you enabled “Reverse Rotary Direction”?
If you haven’t already, I recommend watching our video here:
I memorize that video from inside out , the results are the same, whatever i try… even when i see some familiar shape, when try to repeat the same thing again, it start to act totaly different. So consistency not exist between Lightburn and OmniX. Speaking about my situation with commarker r5 rotary. I believe you guys there will figure something out… and do not forget autofocus button and engraving 3d crystals
Hi there,
I do have both the omni1 and omniX, and the commarker rotary, which works very well in lightburn on the omni1. As soon as I have a minute (probably during the weekend) I will try it on the omniX and tell you what happens.
how the Commarker firmware handles rotary jobs — it’s not a controller LightBurn officially lists, and I can’t find a confirmed success case. It might be that the driver protocol only partly overlaps with what LightBurn sends, or that a firmware flag or .cor file is missing to tell it how to switch into rotary mode properly, but its not my best area, so hoping someone will chime in.
