CNC Laser and Lightburn

Is there anyone out there who can tell me what I am doing wrong?

I have a Workbee Z+ and have an OptLasers 15W laser attached to it.

When I'm using the laser through Lightburn (Lb), sometimes, when I switch everything on, the laser shows up as 'connected in the 'Laser' window, but sometimes it shows as 'Disconnected'.

Has anyone got any idea on why this is?

By using the laser through Lb, I don't have to keep changing screens to save Gcode and then load Gcode in the Workbee.local window, I can just press 'Start' in Lb. Secondly, because I'm using Lb, it allows me to frame the work on the wood etc.

Many thanks in advance.

Merv

Hi Merv,

Thanks for your question.

Are you using USB to connect Lightburn to the machine?

Hello

Yes it is connected via Cat 5 through a converter to USB.

Any thoughts?

Thanks

Hi Merv,

Thanks for your message. Ok, but how is Lightburn talking to the machine, over the Cat5 cable?

Hello again.

It is linked as follows. CNC - CAT 5 - Cat 5 to USB converter - USB into my windows 11 laptop and finally Lightburn.

Since I started this thread, Lightburn no longer talks to the machine at all. I now have to save GCode and then load via the normal Ooznest interface.

On the surface, you may think that having to do this is not a big problem, however it prevents me being able to frame work or tuning the laser on to frame. It really slows the process down. Just pressing start or frame in Lightburn was a great bonus.

Just as a side note. I have never actually used the CNC side of the machine. You may think this a pathetic statement, but, I just cant get my brain around the programming side. I've tried a number of pieces of software, (trial versions), and can't seem to crack it. I've tried to skim the surface to level it all out on a number of occasions, but the CNC moves a few centimetres in the X direction and then stops.

Hence the reason that I turned to lasering, which I find very easy. It's a bit of a sad affair, that I've owned the biggest machine sold by Ooznest since Last December and NEVER actually used it once. (Apart from the HELLO WORLD, code that is provided). Never mind, I love the laser side. Having the huge bed is a massive bonus. I'm sure that if Lightburn had a CNC side to their great software, I would have no problem. I was paying monthly for Carvco Maker, but stopped after about five months, as I was getting nowhere, I the tried V Carve (Trial) but that was the same. Its not that I haven't tried as I watched hours of Youtube, however the vast majority of the videos expect a starting knowledge that I just didn't have.

Lasering it is then!!!

Many thanks in advance.

Hi Merv,

Thanks for your message.

The issue I have is, I am surprised Lightburn was ever able to talk to the CNC Machine over CAT5. Normally with the Duet Controller, the CAT5 is just for the web interface.

How do you have the machine connection setup in lightburn?

That was not too difficult. I searched for it using find my laser and initially it didn’t work, however I switched the system on one day and noticed it was connected. That’s it!

Hi Merv,

I think you may want to follow this guide: https://docs.lightburnsoftware.com/Guide...

Form the 'In Lightburn' section.

I cannot say for sure if this will work though.

Many thanks for your advice. Sorry for the tardy reply, I have been ill and out of the game for a while.

I will give it a go.
