I have the ls3020 laser cutter and I started experiencing this problem lately.
The machine restarts randomly during operations, both during executing a command or just running idle. I have no idea what is causing it. In fact yesterday I cleaned the machine really well and lubricated the parts in motion, cleaned the lenses and everything.
The temperature is well controlled at around 19 degrees. The tube time count is somewhere at 150 hours. I tried multiple files just in case this is generated by a conflict between the files and the machine. The water looks quite clean too.
I managed to capture few restarts on video. You can watch it by accessing this link https://drive.google.com/open?id=1VOwAv ... s_KLs0l-_7 It's a google drive link, all safe. The neon tube went off few weeks ago and could not find a replacement locally.
I thank you all for your help in advance.
