There may be a miss-understanding of its purpose,or I'm useing it off its purpose. I am feeding lincurve with the absolute z position as delivered to the motion input from the stepgen. So it knows where on the bed it is. That allowed me to setup a laser, useing a knife edge in the tool holder,and measure the bed wear error, program that into the lincurve module, who output is then applied to the offset to correct this error in the x axis as it moves in the z plain. So I can turn within a thou over 3 feet of z motion that has 13 thou of bed wear right in front of the chuck. Thats how I use it, but the offset module doesn't care where this offset signal comes from, so don't be afraid to let your imagination out to play with only a common sense chaperon. ;o) > Thanks as always for everything :) > > Leonardo Take care & stay well.
