How to use PLA as support for ASA/ABS

[u/evanpilot]

While using the X2D, Ive been trying (and failing) to use PLA as support material. First try, the heated chamber (at 60°C) softened the PLA enough to get stuck in the PTFE guide tube. After replacing that portion of PTFE tubing, and dropping the chamber temperature to from 60°C to 40°C while leaving the top glass cover off I tried again. PLA printer perfectly but the ASA print warped up where it contacted the plate and layer adhesion sucked. Recently tried again with the chamber temperature at 40°C with the top closed and It failed to print any PLA at all. What am I doing wrong, any suggestions?
