Hello everyone, I am facing a recurring issue where my laser machine is not being recognized by windows. I tried multiple stuff but what works just seems to be random and sometimes the “fix” stops working just a few minutes later.
Things I tried:
Uninstalling and reinstalling everything again. This came with an unwanted defect that everytime I open corel laser now, a message asking to connect a printer appears.
Removing the water pump and air pump from the back of the machine and using a different outlet.
Using K40 whisperer and the ubslib
Installing a newer version of corel laser (which worked for a few moments but my usb dongle wasnt working for that version)
uninstalling device using Device manager/restarting computer/machine
What is common in this situation is that in devices manager, there is a message shown in Usb devices that that device “Failed to retrieve device info” or something along those lines.
My laser machine is from a brazilian brand but is very similar to the K40 models I’ve seen around here. It is a Visutec vs6040, if there’s any brazilian out here as well.
My last resort will be testing this on Ubuntu. I got a link from another thread teaching how to mount a usb ubuntu boot, and my question is:
→ What do I do after I boot it in ubuntu? Is it terminal only? Do I attempt to run Corel Laser or do I have to go the K40Whisper line? I sincerely want to keep using corel laser though, if possible.
I forgot to mention that I already tried switching cables, tried other computers and that I cannot make my computer use the same outlet as the laser machine because they’re different (10a/20a)
I had a similar problem with a 3D printer. When it was printing, I left the room and when I came back a few moments later, printing had stopped and I had to reset the USB connection to make it work again.
After a while (a very long while) I noticed that it happened because, when I left the room, I switched the lights off. Fluorescent lights have a big inductor that cause interference on the mains.
You could try to add an interference suppression filter in the mains connection, or better add such a filter to the appliance that causes this nuisance. That could be the pump if that switches on and off regularly.
Booting Ubuntu from a USB thumb drive is an easy way to test hardware and software. You will be using K40 Whisperer or MerK40t since they will work with a stock K40 which has the M2 Nano controller.
Depending on the version of Ubuntu you use, you might have to remove or at least stop the brltty process if it’s running because it often takes control of USB serial devices connected. IIRC the command “sudo apt purge brltty” will stop and remove the process.
And no you won’t be able to use Corel Draw since it’s a Windows-only software since Microsoft negotiated a settlement with Corel and required they stop supporting Linux. The 2 apps I mentioned are very good apps too.
