I am replicating a soft actuator (see pictures below) for my final year engineering project. I am having a lot of problems with stringing. I've tried numerous different specs in simplify3D with no luck. I am using a fresh batch of NinjaFlex and have followed the suggested parameters from the original creator that are,
Flashforge Creator Pro Dual Head
Layer height: 0.1mm
Extrusion temp: 220C
Bed temp: 80C
Print Speed: 20mm/s
Wall thickness: 2mm
Multiplier number: 1.2
I have tried adding retraction, lowering the extrusion temp to 215C, lowering the print speed to 1000mm/min, and increasing the cooling to 80%, all with no luck. I also have a flexible filament extruder I've used, and it has had the same problem.
I have also changed the movement behaviour to have a detour factor of 300, which has reduced the problems but still has stringing occurring in where the travel moves occur (in red).
Any suggestions are welcome, and if you could provide screenshots or printing specs for simplify3D, that would be wonderful.
I appreciate any help you can provide. Thank you!
