Anycubic Mega S extruder TPU Flex mod

cults3d

This is a modification for Anycubic Mega-S extruder (not i3 mega). It fix flexbile filament jam between the gear and filament guide, there are big gaps between stock guide and driving gear. I did print it with 0.1 accuracy without supports. After printing, you need to drill 2mm hole inside of the guide and you may need to make some job with a file for perfect fit if you use stl file with border around the hole, so watch the pictures. Also i replaced stock 2mm PTFE tube with 1.8mm PTFE tube. After this modification it print good with flexible filament, but you should load filament manually (without using the extruder, otherwise gear will damage the filament, when it reach the nozzle at high movement speed and it will not print), and you should use slow printing speed, around 20-30mm/s, may be, 0.5mm nozzle will allow you to print with higher speeds.
