LM3 not powering on

Community Laser Talk
1

I shut down my LM3 last night and when I tried to power on this morning, a white light blinked for a few seconds then quit.
This happens every time I have tried to turn on machine.
Tried unplugging for a while then replugging, same thing happens.

I would ask you to triple check the obvious

Key - and Emergency switcH

then unplug laser head cable, and just on USB try to power on
Same behaviour?

Download unzip

you will notice you have a OLM3 drive in your computer
copy there the .bin file and let it update

I don’t have the USB drive plugs into the computer. Running my CNC presently and used another USB connection on my power supply.
Is there another way to upload that file?

8

could you right click windows menu → device manager
Then expand PORTS and DISKS section and take a screenshot?

Gil, I appreciate your time and trying to help me, but I’m not understanding what your asking.

FYI, I’m using a MacBook

Sorry i missed that you are on mac, you should have a drive in your desktop that is the Firmware drive of the machine

I used LightBurn to originally connect to the LM3
Nothing on my computer

My CNC will be finished in an hour. I will then download the files you sent and connect my computer to the machine and copy that file you mentioned and see what happens.

Now it is beeping 3 times while going from steady red to blinking red and purple

Gil,
Trying to figure out the light code that the machine is throwing off. Beeping with a red then flashing purple then repeating.
How do I get the firmware on to the LM3?
What firmware files do I use?
