For some time my machine places the carvings on my board 1/4" off center. The Carvewright techs tell me to recalibrate my offsets which does nothing to correct the problem as the boards are measured perfectly every time. I always measure the length of every board and compare it to the total length of the sled prior to carving. I've resorted to adding 1/2" to every board and then trim it to the correct size after carving. My carvings come out perfect in every way other than not centering.
Thank you
