I had first installed those Lmcv2u / Lmcv4u driver and after that I have reinstalled Lightburn to be able to select the Install EzCad2 driver and FTDI serial driver. So yes, also the FTDI driver is installed (pic shows otherwise).
I’d look at this section in the docs. It explains what you are looking for in Device Manager if the LightBurn drivers are installed. You many need to use the ZADig method to swap the drivers, it’s at the end of the docs.
I did see the usb in the device manager as seen as my first picture.
And I had seen the documentation, but had not yet tried the ZADig method.
That was the solution.
That was indeed the solution.
It had not yet succesfully installed the Lightburn drivers.
Now I can add the laser by searching for it.
But it keeps swapping between busy and disconnected.
I am still searching the forum for answers.
Changing the fiber laser from JPT to IPG does not work.
I get in the ready state when only the power is on. But when I turn on the laser button, it keeps switching between bussy and disconnected.
Did you import the Markcfg7 file from the EZCad software they sent you when you created the device in LightBurn? That file has the config info for your machine it it. If you did and it’s still not working, I’d recommend emailing support@lightburnsoftware.com to create a ticket with them for assistance.
Lightburn should show Ready in the top left of the laser window. If it does then it’s not a communications problem, it’s configuration or hardware…
There isn’t much point in removing and re-installing Lightburn and/or the drivers… if Lightburn is connecting…
Follow the problem via the flow … if Lightburn is connecting to the machine, it’s not a driver issue… and probably not a Lightburn issue either.
If it’s toggling between busy and disconnected … I haven’t see that… mine goes to framing then to ready when I turn on the fiber… if that means anything.
Lightburn is connecting when I only put the power on.
But when I put the laser on with an other button on the case, I get busy<->disconnected
And also the message “Unrecognised board signature”
And I have tried already 3 USB cables.
Directly to my laptop and not by a USB hub.
I’d suggest you send a note to support… if the following doesn’t work. Kind of going back to what you’ve already done…
I have not seen it like you describe but I’ve heard of the unrecognized board signature… Generally unloading and reloading isn’t the answer… it just means there’s a bug somewhere… in the drivers or the install/remove software.
This thread had success, but it appears he missed a step in the installation somehow… it’s a Windows machine, so no telling… no mention of the busy/disconnected message.
I also have seen that post.
That’s why I tried with re-installing LightBurn.
And Zadig did help to get my LightBurn to find the laser.
EZCAD itself I have not used yet.
I will contact LightBurn support.
Thanks anyway for your help and time.
We are all interested in getting you up and running… Support is pretty quick and since you followed all the listed debug items… They would be a good choice now.
Include this thread in the email, so they can see what you’ve done…
LightBurn replied and sugested that I should connect my usb with the control board inside the laser.
Because there is a sub cable from the control board to the outside of the laser case that probabebly is faulty or in interference with the power supply who runs along the cable.
It still only works with 1 of my 2 usb cables. so for other people, you need to keep that in mind.
Thank you verry much everyone for the help. And offcourse also LightBurn support.
Edit:
And it does work with fiber IPG as JPT (what it actually is).
