Speed after tool change
So why does the speed default to 100% after a tool change when it doesn't change from one print to the next??
I am printing an object which has sections of flex filament. I have selected a compromise temperature which is kept across tool changes, but printing the flex must be done at low speed. If I don't catch the change from PLA to the flex then it tries to print the flex at 100% and that is the end of that.
RE: Speed after tool change
I know it doesn't answer your question, but you can work around this by dropping the max volumetric speed for the flex filament profile. Take 11.5 and multiply it by the speed factor you are using, e.g. if at 50%, set it to 5.75.
This will limit the volume of filament pushed through the hot end per second, and thereby slow down your printing of that filament.

I think the problem is very annoying and I can only hope the fix it in the next firmware. The destroyed so many of my prints because I need the first 5 layers to be printed slower. Please PRUSA fix this its important.
RE: Speed after tool change
I wonder if it is because the speed value affects all motor movement and it would interfere with e.g. the unloading/loading sequence and motion of the extruder.
But yes, ideally it should save the original value and then restore it when the toolchange is complete.

It probably is as you say. I tested it with the dial directly and also in tune menu but it doesn't matter. But I think it can't be that hard to change it back after a filament change.
