Hi All - Just wanted to introduce myself as I've just completed my build. Here are the details: Sphinx 1000x500 build w/ Limit Switches 800w Water Cooled Spindle CNC xPro Board - Hint, $4=1 - That had me messed up for about an hour Nema23's Fusion 360, and GRBL Panel I had a long weekend of struggles in learning how to get coordinates setup, stepper motor steps adjusted, machine homing correctly, etc. All in all I would consider it a pretty good success. Got some test routing done and didn't break any bits yet. One of the projects that I plan to do is routing recessed holes into some aluminum plate. The aluminum plate will already be final sized. With that said, I am trying to find out how to do my G54 offset properly, as I want to ensure the holes will be exactly where I expect them to be. So, in determining 0,0, where would the bit sit. The model has it in the lower left corner. My question is a bit more precise, meaning, would I sit the bit inside the corner, outside on the corner, half on/half off the corner, etc. - Edit: In further reading, it would appear the the 0,0 point is the exact center of your bit, in both directions. Thus, it would seem the center of the bit would be placed right on the corner? Right?
