I did not. I did monitor the internal temperature and it never got hotter that 35°C with a bed temp on 70°C. 70°C is what I use for PLA and PTEG. On ABS I run bed temperature of 100°C. The internal Enclosure temp is <45°C for ABS. This is using the restrictor orifice.
Those temperatures should not affect PLA or PTEG. What kinds of failures are you seeing?
