I have bought an EZ-TRAK II and I am trying to install the linear comps. I have a Starrett Webber Standard Mounted on the table, and I program a move of 20 in. The indicator is zeroed out at the right side and I move the table to the right or minus direction. After the move I read the indicator at the 20 in. programed move. The indicator now reads plus .006 I install the parameter code and write in minus .006 in the x-axis box and press plus or save. I turn the machine off, reboot the machine, check to see if the minus .006 is in the x-axis box, then home the machine. I program the 20 in. move and the distance remains 20.006. I removed the BMDC Board, cleaned the contacts with an eraser, reinstalled the board. This did not make any change. I ordered a ner BMDC Board and went through the same process; however, no changes have been made in the 20.006 Why can I not get the correct reading at 20.000?? Zukes 3140
