Long story short.
I bought a cheap a3 engraver from hong kong.
Came with a 12v 500mw that lasted all of 3 hours and then refused to burn anything.

I bought a 2.5watt that came with a little daughter board.
 
First pic is my current controller board, an arduino nano.

Just has a 2 pin output for a 5 or 12v laser diode. Works well actually - currently using a 1watt 5 volt, designed for those teeny tiny neje usb powered engravers.
Was really cheap and works way better than the 12v the machine came with.

second pic is the 2.5 watt laser and board. Has 2pin 12 volt power plug and two 2 pin sockets on the board.

third pic is the two 2 pin sockets on the daughter board, that I presume are supposed to connect to the controller board.
For the life of me I cannot find any such controller board online.
The eleksmaker boards have three pin connectors. The arduino also seem to have 3 pin connectors.

There are a lot of people selling these lasers with the same daughter boards - so presumably there must be a way of utilising them.
I'm currently drawing a total blank.

Please help :-)

You could use the "motor" connector on the Mana board (2-pin switched 12V) or since the laser driver board has a TTL input (CN5) you could use that with the "laser" (3-pin) connector.

On your board you would have to get the TTL signal directly from the Nano (pin D11).

how do I plug a 2 pin connector into athree pin connector.
Where would the pins go and what does the redundant one actually do ?

Also, there are a lot of these things being sold - so somewhere there must be a correct board for them to connect to.

I'm not au fait with electronics and don't solder - so simple solutions and explanations are preferable :-)

If necessary I do have a mate who can solder stuff.
But I'd prefer to just have the right board.

I found some info by searching for "YRT-005". Use the quotes.

well i got someone asking the same question on the eleksmaker forum - no replies.
A bunch of sites in chinese - presumably selling the board, and a lot of pictures of it.

How it's attached to a board and what board - not a thing ;-(

would this work ?

I count 7 unused 2 pin connectors.

Ah ha: https://www.laseraxe-customize.com/online-store/Laseraxe-USB-CNC-3-Axis-2-Phase-4-Wire-Stepper-Motor-Controller-Driver-Board-CNC-Laser-Engraving-Machine-Mainboard-p105357265

Even has endstop connectors. That's something I'd quite like.. As far as I can see it's got all the right connectors and all 2 pin.
Seperate fan socket too :-)

Presumably this would work with lasergrbl ?

Just found a 3d printable laser holder that screws up and down. saves mucking about with the lens cap. So I'll do that in the meantime :-)

To me the important issue is it compatible with GRBL firmware? Second is can you make/get cables?

cables not an issue, I can make them or probably just buy some.
As far as I can see from the laseraxe section of this forum, it comes with grbl installed.
