Great success with Ninjaflex

The trick seems to be to not have the robox pull the filament off the reel, but to just have it hanging or lying lose so it can pull it in without any resistance, print at 40% speed, 1.15 flow rate and 225-230C, bed at 0C, the prints are ultra strong and near impossible to break. The picture dont do the actual prints justice.

@svelo Nicely done! What model print head are you using?

I operate two Betas and one Production Robox.

@bhudson the dm head

I haven’t got that good results (attached test part is the best I have got). Printing quality kind of depends from a day. Some day better and some day worse prints. Lower parts can print more easily. Outer perimeters does not stick well if not enough temperature. Only used smaller nozzle. Tried bigger nozzle but seems it was not able to output enough filament even with higher temperatures (had to use also much higher flow rate and much lower feed rate multiplier with that). Using S2 head. Would there be some difference to DM head? Is there any instruction how I could calibrate extrusion width with AM (biggest issue is that you get gaps between perimeters)? Seems AM is missing some parameters like extrusion multiplier (http://forum.makergear.com/viewtopic.php?f=3&t=1964) also so not able to adjust that.
