sudden connection problem #2422
Comments
|
Check you are using the right COM port - I have unplugs mine a few times and then plugged it back in and windows in its wisdom had changed COM port number and so I needed to reselect in LaserGrBL |
|
Try this: menu grbl, LaserGRBL settings, in first page enable both hard and soft reset on connect options. |
|
Thanks, khtirnings and arkypita! Unfortunately this does not solve the problem |
|
same problem here, even installing older versions..... also my lightburn works very well |
|
I was using Laser GRBL without issue, and ran a windows update during a break between burns. After the update, the identical problem at the start of this thread occurred. Switched to an older PC without any windows update, and the same revision of Laser GRBL worked flawlessly. It seems like MS changed something.... |
|
I am having the same issue. I have tried everything I could think of but will not work, I have etsy orders to complete and I do not no what to do now. I have tried the things suggested in this thread with no joy. Has anyone got any other suggestions for us? |
|
Any update on this -- same exact issue here - |
|
Yes I have sorted it
If you go onto the program at the top you will see tools you need to download the new driver from there and then mine worked I spent 7 hours working on it but try it and let me know
Thanks

I had to uninstall the 2024 version of the CH340 driver that came with the windows update and then installed the 2019 version using the tools tab in Lasergrbl. Just doing the install did not work. Check in device manager when connected to make sure the correct version is installed. |

Any luck

Yes. Doing the uninstall off 2024 and install of 2019 CH340 driver fixed the problem and Lasergrbl now connects to my Longer laser. |
|
no luck yet....
one more time, I will uninstall grbl ( actually testing v7.11.0), reset
all, uninstall drivers then install everything again from zero. etc etc
etc........
hope it will work back again...
as jugglers says.... Eu acreditoooo!

I have been using laserGBRL with a laser engraver (iKier K1 Pro 1064nm 20W Fiber Laser) for months and it has always worked fine (system Windows 11). Now laserGBRL suddenly can no longer connect to the laser engraver. Lightburn does work.
Start LaserGBRL and click 'connect'.
Error message:

Does anyone have any idea what could be wrong? Thanks in advance!
