LightBurn can’t find my Laser Atomstack 5a

[Tebrown (T)]

I bought the Atomstack 5a . Put it all together. Downloaded lightburn on my MAC. Didn’t find the laser. Lightburn support had me install ch340 driver. Did that. Restarted still can’t find the laser. Laser is plugged in and usb is plugged in from laser controls to computer… not sure what to do now. Help me please!!!

It’s probably still a driver issue. Double check that install.

You can search this site for you laser and see if you can find something similar. Seems to always turn out to be drivers…

Good luck.

Hi Im really really new to all this. Just put my atomstack a5 pro together last night. I’ve never used a laser engraver before in my life. I am having the exact same issue as above. Except my laptop is a dell running on windows. I’m looking the internet over to try and get software that will recognize my laser. I have LaserGRBL and now LightBurn. But neither are recognizing my hardware. Any help at all would be greatly appreciated. Thank you!

From another system but most likely this same issue:

3018 Pro not detected

LightBurn works fine. The drivers for your laser are the issue. MacOS ships with a driver that conflicts with the drivers used by FTDI devices. It’s also possible that your board uses a CH340, which you might not have a driver installed for. I do not know which chip your 3018 uses for communication. This is to fix the FTDI issue: Ch340 MacOS: https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/all#mac-osx
