The Mighty Longer Ray5 Laser Engraver

Longer Ray 5 Laser Engraver

Page 3 – The Longer Ray5 Manual, operating the engraver and much more

I could fill up a lot of space with specs and instructions, instead I’ll direct you to the online manual – I could not find the full manual in their list of documents but stumbled upon it in the WIKI.

The engraver like all other laser engravers I’ve used, readily operates over USB with packages such as LaserGRBL (free) and Lightburn (much more comperhensive but not free).


A potential big feature for engravers for me, is WiFi. Up to now it is possible to engrave GCODE files over WiFi – but the reality is not quite living up to what I at first imagined. My office is not that big, my computer sits on one side and my bench for the engraver is on the opposite side, so using USB is less than convenient. I looked all over to see how I might start the process of using WiFi and stumbled on it. The control panel on the engraver has an option to connect to your WIFI access point – so I selected my access point, entered the password and “connected”.

The online manual recommends you make a note of the IP address in the LCD panel, but it gets better. I have a WiFi scanner on my PC and they’ve given the device a NAME (I’m used to this when handling Tasmota IOT devices) – and it is grblesp. More specifically on my network where the default suffix is .lan – I can go, in my PC, straight to http://espgrbl.lan and be greeted by THIS:

The SPEED setting is obvious – but the DISTANCE setting… no idea for now (doesn’t seem to do anything – power possibly?) – as for light levels – I chanced my desk and hit the “OPEN LIGHT” button (BEAM ON would have been better) and on came the laser, thankfully at a low, safe level.

Now, it turns out that using Lightburn and WiFi together with the Longer Ray 5 is a non-starter for now – Lightburn have created some software called “Lightburn Bridge” to fit into a Raspberry Pi – and Lightburn itself has in the “device” section a device called “Lightburn Bridge”. However as far as I can tell, this assumes you can hook the laser to the RPi by hardwired LAN – the Longer Ray5 has only WiFi, no hardwired LAN – so , that’s one option dashed for now.

Back to USB connection – I could not find a profile for the Longer (well, it is NEW) but the standard GRBL profile seems to work ok with manual settings of 400mm x 400mm.

Red acrylic 3mm sheet cut using the Longer Ray 5 and Lightburn

There is KIND OF a way to use WiFi and to test, I popped into PowerPoint, find myself a nice star shape, select the shape and exported as an SVG file and imported into Lightburn (all dead easy)… and found myself armed with a nice shape for an attempted cut into 3mm red acrylic but to burn the star with WiFi, I’d have to export the resulting gcode file so I could import over WiFi to the Loner web interface.

You can of course use the GRBLESP WEB software, despite the Chinese titles mentioned above. I was JUST ABOUT to give up on the WIFI as you’ll see above when it hit me… Lightburn can readily export .GC files – and that otherwise lacklustre, incompletely translated GRBLESP web interface can readily import .GC files onto the SD.

So, in Lightburn, via USB, I set the laser to 100%, 600mm/min and 10 passes (more guesswork than anything else, I know from experience that if I used a much slower speed, I risked deforming or discolouring the acrylic). And lo, I ended up with a near perfect (roughly 20mm across) cut-out STAR…

SO finally, I took my star and with the USB lead disconnected, I exported it from Lightburn and sent it over WiFi to the printer, put a piece of test wood in the engraved – and LO… actually that’s quite do-able though not as convenient as using USB directly from Lightburn – depending on your office/workshop layout.

So there you have it – the Ray5 will easily cut through wood and acrylic (multiple passes to avoid melting the acrylic or making a nasty burned wood surface). Now I’ve gotten this far, the sky’s the limit (well, for coloured acrylic and wood anyway).

That’s me done for now… I’m including some “Review guide” info from Longer below – I was not in any way involved in producing the information below and so I cannot guarantee it’s accuracy – I’ve merely re-worded where the original got too sales-ish, the translation needed work or I didn’t easily comprehend what the company produced – actually much of the info below IS actually useful and there are plenty of informative links:

    1. Hah.. I like it!! I’d love to steal one of those laser warning signs… the one I like the most would have to be on Shutterstock – I can link to that “remaining eye” image but I can’t steal it without ending up in court 🙂 It’s a winner.
