    In the list f machines OX is not listed. Is there a comparable machine? Can fusion 360 work with your recommendations as the CAD?
    I've just ordered the box so I guess I'm committed.

    Whats more important than the machine model is the motors you are using on that machine. If you have OB motors, you're good. If not, check the specs on the motors and make sure the bb drivers can drive them (3.2A Stepper Drivers (Max rating 4A). The BB is grbl based so you need to use a grbl post processor. The one that comes with Fusion doesnt work well. Use this one: swarfer/GRBL-Post-Processor Use OB Control to send it: OpenBuilds Software - FREE Software for CNC Control: OpenBuilds CONTROL and OpenBuilds CAM

    Thanks, I'll wait until the bb arrives and then try a test.

    Any suggestions on connecting to the Blackbox wirelessly / remotely. I would like to use my windows tablet but find connecting with a dongle and USB cable too cumbersome.

    Not exactly what you want, but if you use OB control, you can use the jog widget on your phone. You'd still need the tablet connected via USB. And its another device, but at least you're wireless for 90% of what you need to do.

    So I'm ignorant of the capabilities of grbl in relation to tool offsets..
    In the grbl 1.1 on the black box can we use g41/g42 commands for tool diameter compensation?
    I get confused in the wiki because it goes from grbl to linuxcnc grbl in the explanation.. (there's a difference?)

    Thanks - sorry to partially derail the conversation

    Refer to gnea/grbl > about halfway down lists all the GCODE Grbl Understands. Tool Length offset is supported (somewhat) but not Diameter.

    Grbl Wiki lists what is supported, LinuxCNC Reference helps user understand what a given GCODE does (Only a subset of the LinuxCNC standard is contained in Grbl)

    Hi were you able to get the BlackBox to turn on spindle on through the VFD ? If so would you mind sharing info on this? I have a Huanyeng VFD and can't seem to get it to start the spindle with the M3 command. I've set PD01 and PD02 on the VFD both to 1 but no luck!

    Make sure your jumpers are set correctly: OpenBuilds BlackBox 4X Documentation

    You also need to send an S command with M3. ie. M3 S1000

    Just got my BB. How do I get Swarfer/GRBL post processor into Fusion 360? I've downloaded it and gave it a try but can't find how to do it. These screen shots are what I have downloaded.

    Followed directions but still didn't show up. There is a GRBL in the file that was updated June 3, 2019.

    The recommendation from Peter showed up and then disappeared. Not having much luck. I wonder if I downloaded the right file?

    You need to copy the OpenbuildsGRBL.cps file into your Fusion 360 post processor directory. @sharmstr's link on how to use a local post processor tells you where that is.

    Here are the steps:

    Go here: swarfer/GRBL-Post-Processor

    Click on the big green download button.

    Click on download zip.

    Unzip the file.

    When you are ready to post, click on the 3 dots in the "configuration folder" field

    Find the folder you extracted and click open.

    Now down in Post configuration, select OpenbuildsGRBL

    We know this works since its how we all do it :) Okay, maybe just me.

    I think you need to go one more level deeper. c:\.....\GRBL-Post-Processor-Master\GRBL-Post-Processor-Master. Basically, you need to select the folder where the files are.

    I just went through the steps I gave you. I exacted the files to my desktop like you have done. The extract will create two levels of 'grbl-post-processor-master' so you need to make sure you select the one that's inside the other. (I have an appt and wont be back for a few hours. Good luck :)

    Thanks shermstr
    Got it to work so I assume that I'll open it from my desktop when needed as it is not listed in the configerations. That works for me.
    Now to finish the BB assembly.

    I understand the software and controller works for a router table, but can it do z touch offs for plasma if I use a floating head?

    I want to use Ohmic sensing so the Z axis can drive the torch down until it touches the plate and then move up to a certain height that works for the thickness of sheet metal I'm cutting, the Z-probe Openbuilds offers is similar, will it work?

    The Probe input on Grbl is non continuous (can only used for intial height sensing)
    See docs.openbuilds.com/blackbox > plasma wiring page shows the use of a floating head switch
