Greetings all; The little monsters ways have been tightend up and it should carve to about a thou tolerance for a few days anyway.
Currently using homing switches, with figures in the ini file that while not accurate, are at least consistent, which I need to redo the Z axis for the size of the new tapered clamps. And I'll likely restore that yet today. But I need something I can tie into a G38.2 in order to do a fine tune of the base G54 co-ordinate map to establish a true zero diamater at x=0.000. I am thinking of some sort of an insulated holder I can clamp in the chuck, with a bit of give so that I can start the spindle in reverse and even though it may be a few thou off-center, a cutting tip would just slide along, and if I can access the time open and closed, drive it to a 50% duty cycle, then add the probe radius to the x value and apply to the G54 co-ords such that 0.000 is x dead center. For repeatability I should so something similar for the z but the shape of the tool tip would tend to muck that up unless I only drive x to about -.001" for that measurement. So is there someplace in the linuxcnc memory where I can access the elapsed open or closed times of such a cyclic contact? And make those times available to gcode for the math needed?
