I am working on a Jones and Shipman progrind 1045 that is giving an E 228 APC alarm and z axis 300 alarm. I spoke with the Hardinge rep and he told me that I needed a programmer to fix It. The shop rented it and its a handheld powermate -i unit. I cannot find anything about this programmer in order to the manual reference position return, and if it does, it seems like a different answer programmer. The rep I spoke with is not answering and the steps he told me to take are lost due to sleeping since then. Any help would be appreciated
