PLA printing

[Pietro6363]

Hello I am new here so please be patient.
I got the Felix 3.0 with the dual extruder thinking to do the support with the water-soluble PVA, but I am not having much luck as I end up with a bunch of gobs and the PVA really does not want to stick.
Anyone know if there are good settings for temperature, speed etc that might improve things?
Thanks,
Pietro.

I print it at 215 and at 30% speed , if you go to fast the pva wont stick to the bed and if the temp is nog high enough it wont flow correct.

How well does PVA stick to PLA? Would it help to put down a layer of PLA on the bed for the PVA to stick to?
