A few things about lasers ..

This year I got myself a Laser Engraver, a Longer Ray5 10w, and here are some things I've noticed about it and software that aren't mentioned in forums, instructions manuals or documentation.

Telnet port

The Telnet port is 8080, connect to it by writing "[IP adress]:8080". The standard for Telnet is port 23 and port 8080 is used for webservers, so you can see how this threw me off a little.

Squeeking noises

I had a squeeking noise and a lot of resistance on the X-axis. This turned out to be the two alignment screws holding the laser module that stuck out a bit and scraped against the rail. Not, as every forum would have it, incorrect belt tension or poorly lubricated rails and bearings.

Speeds

2.000mm/minute is a normal top speed when using the laser. While the Ray 5 is supposed to be able to move the laser at 5.000 mm/minute this is rarely achieved and speeds above 2.000mm/minute usually results in an error.

1.000mm/minute and below is a more common speed when cutting anything but long, straight, lines. Complex vectors usually shakes the machine to much and triggers the movement sensor.

Laser Power

Laser power is expressed in Watts in reality, expressing it in percentage in documentation is useless since 50% of 10W or 60W are two VERY different amounts of power. Yes, I'm looking at you every person who ever posted on Thingiverse.

SD-Cards

SD-Cards come in a variety of sizes and transfer speeds. The one that came with the machine, and any cheap ones you may have, are useless for anything but small and uncomplicated patterns. This is because the cheapo Arduino clone in these machines, as well as the card itself, can't really handle the transfer speeds. If you're trying to run a complex pattern on your machine I advise setting your laser to AP (Acces Point) mode in the wifi settings, connect to the new AP and use LaserGrbl (see above Telnet note) to directly stream the gcode. Make sure to lower the transfer speed in LaserGRBL.

Happy Lazoring!
