There was some discussion in another thread about problems with a limit alarm when the torch fired. Langmuir made some changes to the firmware to fix the issue. The firmware number didn’t change, but you should re install the 1.3 firmware to get the updated version.
This turned out to fix most of my issues with the limit switches.
