Mystery home position

Post by Dreamaker » Mon Oct 09, 2017 10:42 pm

I assume I am doing something wrong, but I can't figure it out. I always create drawings with the x,y/0,0 in the lower left hand corner. I setup everything from that position. But in some of the G-code display, there is some mystery home position that the router moves to, that makes me a little nervous when it goes their. I have a screen print of the display showing the difference between my home position and the mystery home position. I am assuming it is the result of converting from the drawing to G-code. Can you tell me how to correct it, tell me what I may be doing wrong.

I don't think this has anything to do with the G-Code directly. G-Code is very transparent and human readable, there are no secret coordinates in it.

I'd recommend to google about setting the home position in Mach3:

You could also simply take out the G28 completely if it turns out to be a nuisance. Perhaps you can try that with one program (locate all lines with G28 and remove them) and let me know if that works better for you.
