Mendel Extruder Question
April 10, 2010 05:09PM
I am working on building the Mendel Extruder documented here

It does not say anything about the shaft of the motor having splines. Can anyone tell me if you have build this extruder and if you got good results without it having splines?

If so what is the torque on your motor?

The mendel extruder page is a bit unclear, your motor MUST have splines of some sort. You'd get no grip at all otherwise.

From the Mendel Extruder page:

Mendel uses a thermoplast extruder based on RepRap's Thermoplast Extruder Version 2.0. The principle is exactly the same, but a redesign has condensed the RP parts into one component (click here for instructions on how to get hold of RepRapped parts). The rest of this page will deal with the new assembly only.

You have to click on the link to Thermoplast Extruder Version 2.0 to see the rest of the instructions, which includes a section called "Getting the stepping to grip ".
