I’ve had a snapmaker ray for around a year. I had it set up for use with LightBurn and made a bunch of things, and then one day it stopped cutting through the same stack of MDF I had been using.
I assumed it was a hardware issue, cleaned it, and fiddled and so on.
No improvement.
After a bunch of random screwing around I decided to try Luban (which instantly reminded me that I don’t like Luban). It cut on the first try.
Ok! Great! I’ve narrowed down my problem: somehow I broke my LightBurn install. So I remove the snapmaker laser device/machine definition from LightBurn and grab the one off of snapmaker’s web site and…no dice. It won’t connect over the serial port.
Fine, I grab the old file out of my backups and diff them, and try changing the communications settings (CommPort, baud rate, and so on), still no dice. sigh Ok, hey! The G-Code preamble is different between the new and old machine definition, so I go “back to the old file”, except I rip out the “maybe bad” part of the g-code, and I get the serial port to connect! Woot!
Oh, now I can’t get LightBurn to have a useful job origin and so I can’t get it to cut without going out of bounds.
So maybe rather then mess around with those two files, what is the “current best practice” for setting up a Snapmaker Ray as if it were a brand new laser?
