Another cheat is mount a rotary table off centre (even outside the normal xy envelope) and then you can make larger parts, ok the gcode is not so simple unless you are making a gear. Dave Caroline -- Try before you buy =

This is probably an easy one but I'm stuck. I am a hobbyist using a Taig mill. I want to drill a line of holes in a work piece that is longer than the mill table. The holes are not equally spaced, they get closer together along the piece. How do I stop the program, reposition the workpiece

Just to add a bit to what is all ready said (and I'm doing just that atm on my BP with 42 long parts) I put a dowel in the spindle that matches the nearest hole to the new work area and with the vise loose, Z down and put the dowel into the hole to locate the part from a previous known
