@flyingscot Apart from all the usual improvements and bugfixes that come with every new version of RRF the upgrade to 2.x also brought RTOS as a basis. This stands for Real-Time Operating System and allows tasks to be very strictly constrained in when and how often they need to run, e.g. to have a very close and strict check on temperatures.
With the old way of setting up a trigger you could specify which trigger#.g file was run, but I can't see how to control what happens on trigger now with the new way. Maybe I'm missing something. But it's not clear what it actually does other than pauses and waits.
Ok I have checked the resistance at room temperature and 200 degrees both seem pretty close with 200 degrees showing 450 ohms.
Also now getting a reading of 186 degrees when set at 200 degrees with my handheld temp probe using thermal paste and in the position suggested by Martin.
I have just tried another print that was printed at 190 before upgrading. I started the print at 215 degrees and gradually lowered the temperature until the extruder started skipping at 205 degrees. Retraction has also been reduced to 0.8mm to avoid hot plastic being drawn back into the cold area of the nozzel.
Looks like I will need to print at higher temps than before.
