Has any testing been done with the REV 2 motherboard being sent my Commarker to address the inconsistent rotary operation with Lightburn and the Omni X? Just asking for anyone who may have received it, thanks.

We don’t have one in hand yet, but if you do, we’d be eager to hear your results.

Ater two days of testing new motherboard, i can cautiously say it is working. For now, 0 problems.

How was the install procedure?
After seeing the video, easy. 10 minutes.

Well my installation didn’t go as well 
. The lift motor works to lower but not raise back up and now I’m also getting an error that commarker studio can’t read the parameters. Reseated all connectors and did a second step by step verification with the video they sent to follow. I’m curious if the dip switches are not set correctly at this point other than a bum board sent to me.
Lift ended up being a loose wire on the connector. Ended up putting my old board back and thinking they need to send a tested board for the comm issue.
Running with the new board. Lesson learned is don’t do this on the weekend where you have little to no support in case you have problems like I did. The loose wire threw me off to thinking I had issues with the new board. Also the parameters issue was simply not saving to the unconfigured board which I had to do by choosing save instead of load parameters. One final test is to do a tumbler test.
I received my Omni X in early November and managed to get it working with LightBurn (only had time for a quick test). Unfortunately, the rotary behaves quite strangely. The 3200 steps per rotation value provided by Commarker seems correct, as the axis travels exactly 360° when running the test.
However, the engraving (just the word “TEST”) starts with very wide letter spacing and becomes progressively narrower. I also tried enabling the “Reverse Rotary Rotation” option, but it didn’t resolve the issue.
Could this problem potentially be fixed by the mentioned Rev2 motherboard?
I highly recommend requesting for the new board. When I asked about what fixes this board had they told me this. Original board manufactured in March by the way.
Final update: Additionally the rotary works perfect now and lightning fast with lightburn! Using 3200 steps per rotation.
“The most important purpose of the new mainboard is to fix potential software compatibility issues and hidden risks that may exist in the previous mainboard.”

Thanks for those photos! We haven’t seen the board itself yet.
We’ve diagnosed the rotary issues down to some commands we’ve never seen being sent to the Omni X over the usb comms via a Wireshark log. It looks like Commarker has their software sending bespoke commands to adjust motor parameters depending on which rotary axis (roller or chuck) or if you have the linear slider installed.
Rather than force everyone to install a new driver board, we’re working on software supporting this switching, but we want to do so in a way that is more future-proof than a one-off solution, because we’ll probably see it again.
