Also, I just want to add ... I am the absolute beginner and at the bginning of my learning curve. I have just started to read the older posts in order to educate myself ... but any tips on what I'm doing wrong re above would be appreciated. One other question too ... The home position on my screen is set at/in the lower left hand corner. Thats cool. I've got my console positioned so it mimicks the orientation of my table. But the home position on the table is set at/in the upper left hand corner - making my arrow key for moving the gantry backwards on the Y axis. How do I change the home postion on the table to reflect what I am seeing on my screen? Is it something to do with the minus limits in the Machine Setup tab ... and putting - (neg) signs in front of the figures? I'm mucking around with this now. Cheers.
