Not being a machinist I have a question about homing and tool offsets. I just started developing my tool table a couple of weeks ago and enjoy being able to swap tools and have confidence that It will continue on where you would expect it. Whoop whoop!!
My assumption (big mistake) is that since turning is typically done on center and that all tool cutting points have their x axis offset from machine zero to the centerline. I thought that when I homed/ref'd, that machine zero would be set, and, the XDRO would adjust to reflect the current tool offset in effect. As an example, if tool 1 has an offset from home and entry in the tool table of -3.1255 I would have thought that after homing the XDRO would read -6.251. On my machine the DRO is unaffected.
a. Was my thought process wrong?
b. Should I change the ref x button to have a script that refs x and then reads the current offset and sets the xDro to that number?
TIA
