Hi, SandervG
I found that phenomenon while I'm trying to print PLA+PVA combination, but it is not about combination.
It is about the printing speed of specific layers.
I'm using 'support layer interface' already but it affect between printing model and support, not between support and raft.
I attached a gcode that shows this speed problem.
I set profiles as below.
Raft Print Speed = 25
Print Speed = 100
Support Speed = 80
Initial Layer Speed = 10
Number of Slower layers = 5
Raft is from layer -6 to layer -3 and the printing speed of layer -3 is 25mm/s(F1500).
Printing speed of layer 0 is 10mm/s(F600), and printing speed is getting faster to 80mm/s(F4800) for support at layer 5.
But printing speed of Layer -2 and -1 is 80mm/s(F4800).
I think it is weird that printing layer -2 and -1 with full speed and then slow it down to initial layer speed at layer 0.
Layer -2 and -1 is first/second layers of support, so it is very important to stick the whole support to raft.
I was trying to reduce the printing speed of layer -2/-1 but the only way I found was reducing the support speed.
Is there any way to change those two layers printing speed only, not affecting other layer's speed?

Hello, if I get your description correctly you want to print a raft with PLA, then a layer of PVA and then your model again in PLA, correct? I think you are looking for the setting 'Support layer interface'.
And I believe that initial layer is just the initial layer, not necessarily that one of the model or 'real printing part'.
