    Please could some one tell me the pinout for the green headers I have looked all over the internet but not found any info.

    Thanks Nikki

    Hi Nikki81,
    Looks like the "high power" laser (4 pin phoenix connector) is input power for a diode type laser, it is labeled + and -, only need to use one set of them I would think.. white smaller 2 pin molex connector below it is for the laser itself.
    The three pin is also labeled + and - for 12v dc power input for the drivers and also there is a barrel type instead of the phoenix (green connector) which would be silly too use IMO.

    Link to manufacture

    Cheers
    Gary

    Thank you I have just tried putting a multi meter on the 4 pin phoenix connector putting the firmware in laser mode and sending a m3 command but am not getting any voltage output

    That may be a switched input/output if it is for higher voltage. And as to how to determine which is input and which is output I have no idea. Best suggestion would be to simply contact the manufacturer and ask.

    Looks like the green is the input and the white plug is labeled “laser” that big mosfet next to the plugs is what would switch it... maybe :)

    I have sent the manufacturer a email asking for any info on the board i have a feeling its not switching because of a incorrect grbl pinout. Ill post back if i get a reply

    I am thinking I will replace this board with a woodpecker cnc board. Are there any better low cost options ?

    Hi Nikki,
    Being that this is the heart of the system, Cheap can just lead to more time wasted and boards purchased.
    Xpro would be be the cheapest I would run honestly.. or Arduino Uno and some individual 542 drivers for each axis is even better, and about the same price.
    Much more reliable and robust.
    Cheers
    Gary

    If you go with the individual drivers, you can use your Arduino Nano (if it will unplug from your board) and one of these ($5.99 on Amazon): https://www.amazon.com/gp/product/B00X3L2RJK

    That's what I'm doing to upgrade my Gradus M1 Pro. I got the adapter yesterday and it is fully assembled. My Nano arrived today, so now I'm just waiting for my drivers.

    The version 3 of woodpecker works very well, is stable and simple to use, plug in and you're done, the Grbl is already installed. It includes an external controller with USB and SD card, which allows to move the axes and send the jobs to the machine without using the computer. It's great not to have a computer busy many hours only sending gcode. For small machines, I think it's a great option for the price.
