Memory? What is the Minimum?

Very new to this. Could not enough memory cause ports to disconnect or fail? Laser disconnects mid-burn. All port power management is turn off. Using Asus Vivobook 14, 8Gbs RAM, Windows 11

This runs on some very small systems, so I’d suggest you check the OS and make sure it’s not doing something for you, like turning your usb port off to save power.

It’s unlikely Lightburn, so I’d look at the OS or an environment variable for some other clue. By environment, other equipment starting, cables…

:smile_cat:

No, because a GRBL machine is just streaming the G-Code, character by character, at that point.

To an extremely good first approximation, random disconnects in the middle of a job happen due to communication failures on the USB connection. The usual solution involve getting a better quality USB cable to replace the junk shipped with the machine, plus verifying the cable isn’t getting wiggled / shaken by anything moving around during the job.

The usual advice is a cable with ferrite slugs on each end, although IMO the main advantage of the ferrite is to raise the price enough to pay for better QC on the cable wiring. However you get a better cable, it’s worthwhile. :grin:

Looks like typical USB communications failure, followed by the usual confusion caused by that failure.

Try reinstalling the firmware.

Jeff, have you checked your power management settings? We have a troubleshooting page on disabling the Windows feature that automatically turns off USB ports to save power.

I’ll update our troubleshooting page with directions for Windows 11, but in the meantime here are directions to turn off USB Selective Suspend in Windows 11.

What to thank everyone for their input. Found out it was something in the control module. Nice to see the support you get here when you have problems. Again, Thank you!!!
