If this has been asked before, I apologize but I’m really not sure how to search my issue. I believe I have a setting screwed up but I can’t find where. My grbl based machine (Openbuilds BlackBox) homes and moves correctly per the arrows so that is correct. The issues I have are:
1: The “scale” in the software and the machine are drastically different. If I use the “set laser position by clicking on the page icon” and click in the center of the workspace in the software, my machine takes off toward the back right rear corner. I had to stop it before it got there when I realized that it wasn’t even thinking about stopping in the center. I have no idea where it would have ended up had I not stopped it. If I click 3 or 4 boxes off of the lower right corner in the workspace, it will move out quite a bit more than the 5-10mm I am expecting.
2: This is another scale issue. The numbers in my software read positive numbers in the workspace and the numbers on my machine are in the negative. See below screen shots. The first screen shot shows the position after I homed and the second shows the position after I moved 10mm away from X home and 10mm away from y home. The numbers being reported by the machine are negative.
3: I’ve hit “Clear Origin” multiple times and tried to reset my origin to the lower left corner of my work piece. I hit “set origin” when I get the machine where I want it. I can move the machine 10mm (or whatever arbitrary number) away from where I just set origin, hit “go to origin” in the laser box and the machine goes elsewhere but doesn’t go crashing in to the limit switches which I am thankful for.
My current grbl settings for reference:
