Temperature Mismatch

Third Party Software
1

I normally use a Snapmaker 2.0 F350 with the Dual Extruder module & Cura as my slicer, and set the following in my Material settings (for both extruders):

Printing Temperature: 215.0

Printing Temperature Initial Layer: 215.0

Initial Printing Temperature: 205.0

Final Printing Temperature: 200.0

I also have the following for Extruder 1:

Standby Temperature: 175.0

And the following for Extruder 2:

Standby Temperature: 150.0

However, there are certain points in which both extruders have temperatures of either 200.0 or 205.0 (at the same time), and are not in the process of changing, they both just stay there until the next extruder switch. These are not Standby or Printing temperatures, so they should never be staying at those temperatures, especially at the same time. At this point, it hasn’t caused enough problems that it is unbearable, but there may come scenarios where it is. I have noticed (unsurprisingly) that there is more oozing when this happens, which is obviously not good. This only started happening very recently, even though I did not change my setting (at least none related to temperature). Any ideas?

Look in your gcode file and try to understand what happens to temperature control, would be a point to start.

I was initially thinking that Cura might have some kind of minimum standby time, and decided that it wasn’t worth letting the nozzle cool off. But I don’t see anything like that in the Documents.

The docs (sorry, no anchor ids, so you’ll have to search for Standby Temperature) do mention that it can be set in multiple locations:

Tip: This setting is visible and can be adjusted for individual prints in the Custom Print Settings, but it is also part of the material properties in the material manager.

If there is some kind of minimum standby time (I don’t know if there is, but it wouldn’t be a bad idea), the scenario I describe lasts for over 30 minutes (maybe more), some it would need to be a pretty extreme value to explain my description.
