Lost connection light burn xtool D1 20W

[FabienRB (Revil Baudard)]

Hello

I have a xtool d1 pro 20W laser and I’m running it on LightBurn I’ve been working with it for 1 month, everything is going well but to date I have lost connection on my last project during cutting.

I have no problem during the engraving whatever the duration. LightBurn always loses connection during cutting.

With the xtool software the same file works.
I have a MacBook Pro m1 And a Windows 10 pc. The problem is the same.

I have read the various help:
Cable replacement.
Installation of drivers.
Nothing works…

Can you help me ?

Thanks

One of the emerging possibilities is that LightBurn may have trouble with the xTool D1 controller Mounting itself as a drive. It was discovered on other engravers, but the processor is similar if not identical.

On the windows 10 PC, check out the video in the last post of this thread:

LM3 stops in middle of burn - several times

I also had a similar issue, I could not get past ~5 mins doing a fill. I tried all of the usual mods, stop AV, Wallpaper, ScreenSaver etc etc. I did disable the storage device & then tried my test job again, but is stopped after 5 mins. I then re-started my laptop & started my layout that always failed & it finished the job after 31 mins. I have no idea why rebooting completes the fix, the drive is still showing up in the device manager after the reboot as it was before the reboot.

Please follow the 2-3 steps and test to see if that is happening and if this approach allows LightBurn to operate the laser without losing connection.

Which xTool D1 Firmware are you currently running?
You can see the exact version number and copy it from the Console window in LightBurn and paste it into a reply here.

Hello and thank you,

I tried the solution of the video but I is not the line : espressi mass storage usb device

I just did another test. My laser loses connection when I go over 70% power. Below I is not losing connection.

Do you have a solution ?

Thanks

This could be a sign of a bad power supply. When voltage drops, the connection is lost.

Ok but why on XCS of xtool it works.
and
when i draw from lightburn i don’t have this problem,
it only happens when i import files

[berainlb (PY)]

So this is not a single condition issue? Seemed like you were saying that power alone could trigger the issue. It may still be power if it’s also associated with motion. Higher motion would require more current.

Ok but why on XCS of xtool it works.

Are you running the same thing on both?

@FabienRB

it only happens when i import files

Can you provide examples where this is not occurring for native files and occurring for imported files? Note that in reality, once imported there should be no difference in content.

Yes but not in the same format xtool does not take AI files

I managed to finish the file with a power lower than 60.
With the laser head unplugged the work is finished.

thank you for your help
