    Hi,
    I'm looking at upgrading the Smoothieboard 5XC on my OX to an OpenBuilds Blackbox controller due to the simplicity of the Blackbox design. However, I want to have it run my CNC spindle in addition to a laser (JTech 2.8W). Of course, only one would be used at a time. Is there a way to do this?
    Thanks for any help!

    You can wire a toggle switch into the PWM line to switch the PWM signal between the two?
    or use a DSDT relay with the Direction signal/ coolant signal to switch between the two using gcode.
    Or just wire both in parallel and only power on the relevant tool?

    Thanks for the quick reply! I love the toggle switch idea as it's so simple. I I ordered my Blackbox over the weekend in anticipation that I could do it with no problem. Can't wait to get it!!!

    You may also need to setup your CAM software -> gcode headers to include a $32=0 for CNC work and $31=1 for laser mode :)

    That's good to know. GRBL is completely new to me as I have been using Smoothieware.

    :) Luckily its a lot simpler! Have a bedtime read through github.com/gnea/grbl/wiki (And yes also a lot less reading than the Smoothie wiki)

    Have you gotten to put this together yet? I am working out a similar set up. I had been doing the parallel wiring option, but want to clean things up a bit.

    I have everything wired up and did a test with the laser with success. I'm waiting for a new spindle controller so I can use the 0-10V PWM as my existing one burned out recently. Everything else seems to be working well.
