    Help using new Laser for SainSmart Genmitsu CNC Router 3018PRO

    Hello, I was wondering if someone could help me.
    I bought a new SainSmart Genmitsu CNC Router 3018PRO kit which came with the spindle.
    I followed the directions and flashed the firmware to GRBL1.1F.
    GRBLControl(Canadle) only seems to connect at 115200.
    I was able to open a sample file and carve a sample project. All was well.
    The control board I have says woodpecker 3,.2a

    I decided to order the blue laser accessory from sainsmart.com (SainSmart Blue Laser Module Kit for Genmitsu CNC Machine 3018-PRO/3018/ 1810-PRO).

    I installed it and installed the program LaserGRBL, installation was straightforward, 3 pin cable to 3 pin cable and followed the directions to add the extra 3 buttons in the GUI.

    When I connected it, the GUI connected to my unit, but only after I had to press the reset button on the control board.
    Then I plugged in the power and the laser was on and stayed on burning. I made sure the little white button was in the pushed in "on" position. I was able to control the buttons with the X/Y/Z axis while this was happening. The laser buttons were reacting but they didn't do anything to control the laser. After about 10 seconds I unplugged the machine.
    I tried again with the little white button out, not in, I thought maybe on meant always on, overriding the GUI, but it just stayed off, no gui button did anything to turn them on. The X/Y/Z axis was working ok.

    What's the issue ?

    Also to note, there's a power supply on the laser control board that came with the laser. I'm not using that since it didn't come with it's own power supply. I'm assuming I don't use that and just keep using my main woodpecker control board power and it somehow fed the laser it's own power.

    Is there a way to check what firmware the woodpecker3.2a board actually is running?

    Depending of the laser power module value you need to have an external power supply added to the laser control card , but I assume you have figured that out now and have the laser working by now ? . I have a 5.5 W laser .

    I contacted Sainsmart and they said I had to upgrade my control board which fixed the issue. I guess they were incompatible.
