Melting bottom carriage plate
Has anyone figured out a work arpund or solution to prevent the bottom plate on the extruder that's closest to heater block from melting and warping from long hours of printing? I did a few 16 h prints last few days I and looked at it and aure enough it's melting and warping. Maybe print that part in a different material? Prusa prints them in petg don't they?
I'm referring to the plate that holds the bottom of extruder assembly to the lower cross bar.

I finished reprinting all my plastic parts for the MK4 in PC Blend Carbon Fiber just yesterday... I'm quite sure that that material would be a solution to your problem.

I've had a silicone sock on mine from day one, but I still had some melting of the original PETG part. I think it's worse if the heaterblock isn't oriented perfectly square. I reprinted all the parts in ABS and I think that's had the biggest effect. The combination of ABS, sock, and keeping the heaterblock square (e.g. with this or this) seems to have stopped it melting.
