Howdy There! New user testing out the trail of lightburn and I am unable to connect to my AWC7813 controller. It works just fine with laserCAD. I have done/tried the following things:
1.Uninstalled/Installed the latest download of the USB driver that comes from Trocen.
2. Tried the auto detect wizard and it doesn’t find anything. I also made sure laserCAD was shutdown.
3. Manually adding a laser both with just USB and USB/Serial and it just says disconnected and wont’ send any signals.
4. Swapped USB cables (LaserCAD works).
5. Went out and installed the FTMI Drivers hoping it was an issue with the virtual com port, but it doesn’t look like this is how that driver works as it doesn’t show any com port or VAP in the device manager of windows 10.
6. I have restarted the computer and the controller multiple times.
What else should I try? Trocen says this controller is supported by lightburn and I would love to get away with LaserCAD. Please take my money
Hi James, It should be connecting to a Com port in ‘windows’.
On the laser panel next to ‘devices’(think it says ‘choose’) change that to auto and see if that helps.
Also have you tried right clicking the ‘devices’ on the laser pane?
Trocen doesn’t use ‘Serial/USB’ for most of their controllers - only a handful of the older ones work that way. Click the ‘Devices’ button, double click your controller, click ‘Next’ to skip the ‘Trocen’ screen, then choose ‘USB’ instead of ‘Serial/USB’:
I reached my media upload limit in this post to post the related screenshots, but I just tried it again via USB and USB/Serial and no connection either. I get errors anytime I try any of the buttons associated with the laser and it says DISCONNECTED.
Usually this is a driver issue if you can’t connect at all. Lightburn people would have advised you that your controller isn’t supported if that was the case.
What exactly happens after you select USB and click ‘next’?
1.It asks me for the origin of the machine. I click the right rear and next.
2. it asks me what to call it and the size.
3. It says I am done and it was successfully created.
If I try the wizard I get a blank dialog saying nothing was detected.
Thanks Oz, I just followed up via your support email as I capped out the number of images I can upload. It doesn’t seem to be saving a log, but I do get the autosaves.
Trocen also spent about an hour over a screen share last night trying to help debug it. I added more details in the email, but we didn’t come to a conclusion and LaserCAD still works just fine.
I thought I would update the thread just incase someone runs into this issue. Here is my last reply from support. The windows update and restart didn’t take care of it so I am hopeful that the library update will take care of the issue:
Hi James,
The function we use to query the list of devices looks like it’s failing:
19:23:41.075 D: LibUSB get_device_list failed: -99
19:23:41.075 D: Other error 1
I’ve never seen that before, so I’m not sure why that’s happening.
Try the following:
Run Windows Update
Power cycle your computer
I know that sounds silly, but I’ve seen no end of weirdness when a computer gets into a partially updated state and hasn’t been allowed to reboot to finish it.
There is a newer version of the LibUSB library available. After our 1.0 release, I can try updating it and send you a version with that change to see if it helps.
