Flex filament on powder coated sheets?  

RE: Flex filament on powder coated sheets?

Sticks fine to my powder coated.

Don't expect Flex to work like PLA. It has a distressing tendency to wrap itself around the extruder gear. Not stiff enough to force itself into the ptfe tube.

Run your hot end on the high end of the recommended range - and turn Retraction off.

Thanks! Will order some to try...

Two more hints on helping to get success with flex:

1. In the Advanced Filament settings make sure the "Max volumetric speed" (need at least Advanced mode enabled to see this setting) is used to cap the print speed. For the 85A NinjaFlex that I have, I empirically found a MVS of 3.61 works. I have yet to have a feed problem while printing with this speed.
2. The autoload speed is too fast for my NinjaFlex. So when loading I turn off the filament sensor, and manually jog the extruder axis forward. (Actually, I use pronterface to extrude at a slow rate, recently I've been using only 50mm/min to be super conservative during the loading process.)
