I'm really excited that I mostly have my Ox CNC with the TinyG controller

I’m really excited that I mostly have my Ox CNC with the TinyG controller up and running the way folks said it would. Since resoldering my wiring and configuring my machine correctly, I’ve had almost no problems running the CNC. Today, I tried to mill out a piece of MDF from a cut list of the original CNC I intended on building earlier this year before switching to the Ox build. It took me forever to try and get the dimensions of the cuts correct and the holes properly spaced. It was amazing to watch what this machine could do in a few minutes what it took me days to complete. And, even when I had completed them, I wasn’t entirely satisfied with the result.

One thing I haven’t been able to figure out yet is how to properly gage exactly where my tool head will enter the workpiece when I begin a run. If the units are in mm in both Fusion 360 and CP using the TinyG post process will the tool enter the workpiece exactly at the same spot? I’m having to reset g54 before every operation and guesstimate where the tool head will enter. I usually jog the tool head over from the origin to where the tool head initially enters the workpiece to see if it is set correctly. Can anyone give suggestions on the best tutorial videos to properly set up the origin, coordinate system and off sets in Fusion so that it transfers simply and correctly to CP?

I always just make sure I know where my 0,0,0 point is and in almost all milling operations I do I have to setup my 0 point at the start, but I then at least know in my head where that position is. I don’t necessarily know where the toolpath with enter the workpiece first, but I tend to do air jobs before scary runs just to get a visual. So, sounds like you do something similar.

BTW, one thing I do to test the extents of the job real quick is ctrl+click on the ChiliPeppr 3D viewer to jog to the 4 corners of the Gcode path. That helps me gauge too.

Ok. I’ll try that.
