After lots of failed prints and wasted filament on loading failures , I stopped everything and looked into root causes.

Mon MMU2S fonctionne bien mieux maintenant...
I was able to use M2 x 6 pan-head screws in lieu of the M1.4 x 6 flat-head screws. Makes the bottom part bulge a bit, but I printed the part in PETG and it seems to handle the strain ok.
very well...
