    I just got my Interface device and I realize that I have to adjust my G-code to add the Router Start and Router Stop. Below is the comment made to me on the Openbuilds Facebook page.


    "Leon Sapp It has a menu item for turning on / off spindle for testing purposes, but in reality your GCODE should control those by including M3, M5, M8, and M9 commands in the correct locations in the GCODE file itself. Grbl will respond to these commands as they get streamed to it."

    Can someone help me to understand how to accomplish this from a learning perspective so I can learn how to support myself in the future?


    Thank you,

    --Leon

    Your CAM application, creates the GCODE.
    Each CAM application has its own requirements on what you need to configure, but if its one of the popular ones see docs:software:cam [OpenBuilds Documentation] - for our post processors that adds the correct commands to the GCODE.

    I use VCarve Pro and I am still shy of the information that I am trying to understand.

    Does the Interface tool turn the router/spindle on and off when I run the Job or do I have to edit the GCODE to do this myself? I am confused now.

    VCarve, adds the commands, directly in the GCODE file, because the Post Processor (docs:software:vectric [OpenBuilds Documentation] ) tells it to add it

    You click Run, the file starts going to the BlackBox, Grbl sees the ON commands in the file and does it for you

    Have a read through gnea/grbl for a good starting point

    I have not read through this. I will read through it so I can better understand. I guess I am confused because when I use Openbuilds Control I have to click "Tool On" and select Router. Then I click Run Job and away we go.

    Should I understand that VCarve Pro when it generates my GCODE adds the necessary commands to turn the router on and then at the end of the job turns the router off and returns to home?

    My Setup ... I am using an IOT switch to allow the BlackBox to turn on the router when commanded to do so.

    Thats already the incorrect way, if you are using our VCarve post it will turn itself on after you click Run (if you use our Post)


    Yes! Make sure you use the OpenBuilds Post: docs:software:vectric [OpenBuilds Documentation]

    If the Tool On menu can switch it on, Vectric can as well.

    Okay I just checked my Vectric software and I remember I set the post processor the when I purchased the software.

    Should I now understand that if I run a Job from the Interface device the router/spindle will start due to the GCODE and also stop due to the GCODE?

    I am trying to figure out the same situation. I am running V Carve Pro 9.5 with the Interface. I have the oprn builds post processor installed and I am using it to generate my gcode. My spindle is not turning on. what am i missing? 110 volt water cooled spindle.

    I can turn the spindle on and off through the Interface, but i have no speed control.

    That's for testing. Your gcode sets the rpm during a job

    Does the open builds post processor usually include the spindle commands? Mine is not adding them. Is there something i need to setup for that? I can edit the G Code manually and it works fine.
