Lynng replied to Ncichit's topic in Mark 7 650 Knowledge BaseI am having exactly the same problem with CCI Small Pistol primers with a new 750 and V 1.13 firmware. Attempting to upgrade has not completely disabled the drive, but the original issue was exactly as originally described above. Calibration with clear shell plate and everything looking good. When jogging down or moving down (setup) screen, the primer stage appears to be where it should be, but in operation, the primer is left way high. The shell plate is tight and rest of the operation of the press looks right. I am a dealer, this is the first 750 install I have done but I have done many 650 installs and never had this issue.
