Hi Jacob, The DXE doesn't have EEPROM - that's only for the 8-bit electronics. You can adjust steps/mm on the DXE, but it's a different procedure. You just need to send the appropriate G code to change it. Though, based on what I see, I don't think retraction is the issue here. Give me a call or reply to our last email and we can troubleshoot the PLA issues in more detail.
