First of all thank you very much for your job.

First of all thank you very much for your job. I bought an Eleksmaker A3 engraving machine. I would like to use LaserWeb4. I installed the software and I have an error message “Machine disconnected, No supported firmwaredetected…”
I am working on macOS Sierra 10.12.6 and after several tests I didn’t find any solution.
Did you already have this problem ?


The eleksmaker device is not recognized by osx unless you install the ch340 kext on sierra (not LW) Then should appear as ti.whatever340… you have to select that port to connect with :slight_smile:

Thank you for your Help.
I didn’t find the ch340 kext driver. I only found the CH-340 / CH-341 and it didn’t work…



What firmware have you uploaded to the board?

Unless you have already done this you will need to follow this and flash GrBL 1.1 onto your board. Then config GrBL and LW accoordinly

Thank you Ariel for your support. The board is Mana SE but I don’t know what firmware I have. Follow.this doesn’t work, there is nothing linked.

Sorry I did not paste the link. It’s there now

Thank you it’s ok, I will try to flash GrBL 1.1.
