Hello.
I have a A20M. I bought it so I could use PVA in support structures, But I can´t find a way to setup slicer to use the extruder with the PVA filament when printing supports. I tried with Repetier / Cura and Cura 3.6.0.

Can someone help me? Thank you.

Hi，PVA consumes a very soft material.
Required printing temperature, hotbed: 45-60, hot end: 185-200;

And when using PVA as a support material for your PLA prints, consider adding an ooze shield with at least two outlines. This will have the benefit of priming the PVA extruder after every tool change, which will ensure this extruder is ready to print at the start of the layer.

I find this: https://www.simplify3d.com/support/materials-guide/pva/

I hope this can help you.

Thank you. I will try. Usually I get an error: when switching extruders the hot end is not heated and the printer halts. It seems that cura does not works well with 2 in 1 hotend.
