Idea
I make remix and add some component to create this compact extrusor por pitan with BFTouch.
I redisign some part to make it more reliables.
For the BOM refers to the originals parts.

The "fins" were removed. The entire assembly is screwed and the sense of impression of the pieces is taken care of which results in a very strong extruder.
For the engine an Epson Em-400 was used ,or the EM-383 / 287 also work, any low torque motor.This motors have 4mm shaft, you need to file the shaft to flatten a part.Gears for 4 and 5 mm ar included.
Update nov/11/2018
For the motot the Imax was fixed at 0.4A so , mi drivers are A4988 with R100 as Rs (0.1ohms) --->Vref = Imax8Rs = 0.32V.. Everything OK,
La otra cosa que preguntaron el Desfasaje de Z me quedo a -1.9.pero eso depende de varias cosas pero mas o menos por ahi queda.
Los pasos/cm del conjunto motor/malevo quedo en 400 exacto
