Hello,
I just received my Ortur Laser Master 2 20w and have been practicing burning on wood. I noticed that if I use vector images already just black and white, my engraving finishes fine. If I import an image into gimp, modify it as needed and import it into lightburn and burn, shortly after it starts burning, it finishes as if it was done. I even used Da Big Gimpin plugin inside of gimp to do all the changing of the image for me thinking I was doing something wrong and same thing.
The ‘Homing’ message at the bottom of your log tells you that the controller disconnected and then reconnected. If you have ‘auto home on startup’ enabled, every time LightBurn connects to a device it will home, so that’s what happened - the USB connection was dropped, then re-found, and the device reconnected and homed.
Check for a loose USB cable, electrical interference, USB ports set to conserve power by sleeping or using selective suspend, and so on.
Thank you. I made sure the laptop (windows 10) has the settings setup so the usb doesnt go to sleep or suspend in power management. I have tried a few cables including new cable but the same thing happens. I’ll take a look at the bios and see if anything there is turning it off.
Also why does this only happen on photographs and not clip art/vector images? I had it burn a grid on my table without issues as well as other clip art but when I convert and use a picture is when this happens.
Because photos are huge when sent to the laser, and vectors aren’t. Burning a grid would be 2 gcode instructions per line - one to move the laser to the start of the line, and another to burn the line itself. Images are hundreds if not thousands of gcode instructions per line of image, and it’s a massive stress test of the controller and USB connection.
I swapped out my laptop for my wifes and the issue went away. I did everything possible on the laptop from software to hardware and it just wouldn’t work. Once i swapped out my laptop with hers I was able to print a whole picture. I’m not sure if its an issue with windows or hardware (laptop). So looks like I’ll be using her laptop instead.
I have encrypted drives on my Linux, so then it have to be a fresh Windows install. Will probably do that, only using that laptop for the 3d-printer anyway.
Oh ok. Yea I use my desktop (windows 10) to connect to my raspbery pi that has octoprint on it to write to the 3d printer i have. My laser puts out a lot of smoke so its best to do that in my garage so thats where the laptop comes in.
This thread can be closed. The issue is resolved by switching to a new laptop which makes sense that the issue is either my windows 10 install or hardware (usb on motherboard).
