Thermal Runaway error
-
I have three pulse XE’s model d224. They all have the same problem: whenever trying to print with temps higher than 245 degrees Celsius, the nozzle temperature stays stable for a few layers then slowly drops down about ten degrees depending on the starting Nozzle temp, and then stops due to Thermal Runaway error. I did change the nozzles recently to hardened steel and these printers have been used a lot over the years.
