Printing with flexible filament

Craftbot FLOW generation extruder is very capable to print soft flexible filament.

For good result always do the following:

– Swap the build sheet and print on the metal side. It helps to easily remove the object when it finished. 

– Use low print speed. A very soft material maybe need around 20-30mm/s print speed

– Over extrude a little bit , increase the filament flow around 5-10%

– Turn down or switch off the retraction. Flexible filament cause jam at retract. 

– Use larger nozzle if you can. 0.6mm is very good size for flexible filament

– Use larger layer height if you can, for example: 0.3mm

– Mount the spool above the extruder. You can omit the filament tube. There is an example you can do this:
