Hello, I am a new owner of a used PRT 32x24 ShopBot running version 1 of PartWorks. I am still learning the machine and it is quite fun and quite a challenge at the same time. Today I was playing around with cutouts and was using a 1/8" upspiral to cut though a piece of 3/4 select pine. I set it up to cut .20" inches per pass. It did cut though...(I also used 4 tabs). However, the second, third and final pass did not retrace over the 1st pass. It shifted slightly. I was using a small 9" x 9" piece of scrap screwed to the table with 4 screws. The letter "M" seen in the pic below is only about 2.25" tall. Anyone no what is causing this? If you need more info, please let me know. -Matt
