Adjusting zero on the fly

Hello,

Basic question here. I’m doing multiple runs of the same job and want to adjust the Z height slightly on the fly without lowering and fine tuning the tool. If I just want the zero raised a thousandth is there a way to open the zero tab and simply enter an offset manually? Or do I need to position the tool to where I want it and then clear out the Z offset?

You can use the MDI for this — you just have to do the math to set the origin as required using an appropriate G-code command.

You can also do this on the set zero page; just enter the desired number in the Z field, but be careful; you are entering the position relative to the zero so if you want the zero raised a thousandth you enter a number a thousandth LESS than that currently displayed! (also, you must hit the enter key for your change to take effect)

Thanks! That’s what I thought would work. I tried this but I think it didn’t work because I entered 5.999 and that would’ve been mm and too small to register (I was thinking in thousandths and using metric)

Thanks, I need to learn more about g code and that side of things.

For simplicity between jobs jog to the zero you want then set zero in jog screen. You can certainly set a new zero as above but you better be right.
