Help with Flexfill98A thin part - See pictures
Hi,
I using Flexfill98A bought from Prusa, with standard settings on an Original i3 MK2. The fist layers of the print are perfect, even a fancy fillet, but when it gets to the hexagonal axis all hell breaks loose. Tried reducing the temperature thinking it was too hot, but I read in other flex discussion that maybe I should be raising it instead ?? Anyway, take a look at the pictures and see if anyone recognizes some obvious problem.
The twisted mess is supposed to be an hexagonal axis of about 7mm wide and 28mm tall. I included a PLA print (mounted on a motor) for comparison (the flexfill is shorter because I aborted the print).

Hi,
this could be a cooling issue as in not enough cooling for the small parts. Try to print this part significantly slower or increase cooling.
Especially on those small parts and flexfil this happened to me a lot. As the material is still too soft to be pulled by the nozzle in different directions.

Thank you @johannes.m !
i will try this and follow-up. But it's curious that the rest of the piece is as perfect and easy as printing with PLA. Is there an easy way in Slic3r to tell it to reduce speed at or after layer X ? Or do I have to edit the gcode manually for this? I mean since the problem starts very specifically at the axis I could reduce speed once it gets there, instead of reducing the speed of the whole print. Is there any canonical way to do this?
TIA,
Alex
