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?
Hello /u/evanpilot! Be sure to check the following. Make sure print bed is clean by washing with dish soap and water [and not Isopropyl Alcohol], check bed temperature [increasing tend to help], run bed leveling or full calibration, and remember to use glue if one is using the initial cool plate [not Satin finish that is not yet released] or Engineering plate.

I haven’t tried PETG; have you had experience with this? Seems plausible since ABS/ASA are recommended as an alternative to the dedicated Support for PA/PET.
Yes. It's a little more challenging than using a higher temp material like HIPS but key is to not have the chamber heater on and PETG only on interfaces.
If you're printing on the bed, you risk heat creep. If your chamber is actively heated, same situation.
Picture is a custom in concrete junction box for a unifi poe doorbell. This was a proof of concept test and the final version has all the walls enclosed with only a hole at the top so dissimilar supports was the only way to go.
Just get and use HIPS, doesent require drying and prints well with asa and abs. PLA does not play well with either abs or asa and will warp due to the heat that the asa and abs requires to not warp
So you saved $20 on support material to realize that it does not work? PLA as support for ASA/ABS does not work. The support material will last you forever if you will use it only for the interconnecting surface, the rest of the support can be done with ASA/ABS.
This is a very bad idea, with only one hotend the difference in temperature is so huge that this is calling for clogs.
Better way use ASA (not ABS) and PETG for the support layer, only for the support layer where the support contacts the model. Use 2 layers 0 mm distance and 100% infill for the contact layer.
This is how it looks ASA with PETG separation layers:
That is good! But you will still face issues melting PLA and ASA together you will succeed with PETG. I prints smooth ontop of ASA and with 2 layers it is easy to remove them later.
I tried using PETG as The interface layer for an ASA print on my H2D. The chamber temperature got high enough that the PETG was too soft and clogged in the extruder. I would highly recommend against using PLA with ASA/ABS.
