I own a 2006 PRS Standard. The 2d seems to cut fine, with no position loss.
I'm carving three 6"Lx4.5"Wx1.125"thick moulding profile samples. I've carved several 3d carvings in the past with little to no problems. The level-Z roughing seems okay, but now I'm not so sure. For the carving I'm using a .125" roundnose bit with carving speed at 1.5-ips for xy&z and a step over of 20%. The wood is white pine. While carving on the first blank with the grain in X axis, it begins losing position after a few inches of step-over. It's subtle at first but continues to get worse. By the time it gets to the third blank, XY&Z are all off. I then tried separating the cutting files and carving it in the Y axis. I ran the file and immediately after it began cutting, it dives/plunges into the wood and quickly loses position.
Thanks in advance,
William
