Last year I updated the firmware of my board to GRBL 1.1 on my Nomad 883. I had some issues and Carbide 3D tech support helped me to solve it in no time. Part of the process had me re-flashing my board and my Nomad lost it’s factory settings and calibration. They gave me some GCode to input into the MDI tab that allowed my Nomad to have its initial values. This GCode tells my Nomad where the exact XY center of my table is. This is the GCode I was given:
The second line is the center of my table.
I recently needed to do a flip job and realized that the two sides were not aligned. I was using the rapid positioning center as my zero and flipping on the Y axis. I realized then that the rapid positioning center was slightly offset from the actual Y and X center on the table. I proceeded to re-calibrate my machine. If anyone is interested, I can describe the procedure I used.
I adjusted the numbers I got from Carbide 3D slightly and I’m back in business. I am curious as to what some of the numbers mean. The second line is what calibrates the perfect center of my table. I am curious about some of the GCode. I looked up the GCode Wiki and got closer to understanding. Can someone more knowledgeable fill me in?.
-I don’t know what the first line does. I find it curious that my machine is a Nomad 883 and that the Y number is 883. Why?.
-What is the L2 code? According to wiki G10 use: Specification of what register to edit (work offsets, tool radius offsets, tool length offsets, etc.).
-What are the P5 and P6 codes?. Line one has a P5 and line two has a P6.
Just curious and wanting to learn.
