If that comes back for 79 bucks is this controller any good to replace it with https://www.amazon.com/Engraving-Machine-Motherboard-Driver-Controller/dp/B07RQZGD35/ref=sr_1_30?crid=33MVAFVD1UUYO&keywords=laser+module&qid=1660843621&sprefix=laser+module%2Caps%2C98&sr=8-30

That looks like a similar board to the Eleksmaker Mana SE board I used in the first post on this thread… and I’m sure it would work fine.
HOWEVER, later in this thread (with Jeff’s help), I have successfully flashed Grbl 1.1f on the original JL1 STM32 board it came with. IF you’re willing to flash the original board, you’ll wind up with a much cleaner laser machine that seems to do everything you’ll probably want to do… including rotary stuff. And all with Lightburn compatibility.
If for some reason flashing the original board isn’t something you want to do, you can absolutely swap out the board and get all the same functionality… youll just have to come up with a satisfactory way of mounting the new board to the machine.

Lucky you. I came across this post yesterday and I was disappointed it was out of stock. Looks like you caught it being back in stock before I could. I guess I’ll just have to continue keeping an eye out for it coming back in stock while the sale lasts.

I have one one on order. It should be here today.
@ dkj4linux Thanks for doing the research on flashing the original board…

So all i need is your download and that is it? And of course sounds like i need lightburn.
So may i ask how you edited these? Did you serial in after you used the update? I have never done anything with grbl
As always i ask then research. I think this is what i need
The two files (ROM.bin and upgrade.exe) in the zipfile, a Windows computer, USB cable, and the Centoz machine are all you need to flash the GRBL firmware to the controller. Lightburn (or other sender) comes later… when you start tuning the GRBL settings and using the machine to engrave stuff…

And for the record, you don’t need light burn. Things like cncjs should work, as well as some cam like estlcam or image2gcode. But lightburn is pretty darn useful for laser engravers.

Wow look at you, you are a laser scientist!!!
I probably will buy lightburn. Just to keep it easy. How would estlcam work for laser??
So my search of the forum suggests that estlcam cannot control power just move laser, correct?

You can do some stuff with it. But it just thinks it is a spindle. You still export the gcode and run it with cncjs.

While watching the FedEx golf tournament, put my new Cenoz to work doing its first tiles. I installed my new Z-lift and first did a NWT grid pattern tile with this new 3W(claimed) laser… with Grbl 1.1f firmware on the original JL1 controller and under Lightburn control
Using the test tile, I determined 1250mm/min and 100% power to give the “ best black ”…
image lasered and before paint removal…
Paint removed with acetone… “ best black ” block is far left (100%) and 5 down (1250mm/min)
and finished image (w/o flash). Stern look is to scare away daughter’s suitors…
Finished image with flash… LB processing - Jarvis dither, 339 dpi, all else defaults
