Does the motor sit tightly in the bracket? or should I glue the motor? thanks

The motor does not need to sit tightly in the bracket, it is just enough. You don't have to use any glue!

Hello Robin,

i have a similar Nema with PG 5, a MK7 and would like to ask you how many e-steps / mm filament you are using.
I have actual 475 written in my eeprom and it works well....


I have 439.5 steps/mm! I can recommend calibrating the extruder according to e.g. http://www.instructables.com/id/How-to-calibrate-the-Extruder-on-your-3d-Printer/?ALLSTEPS or http://www.dummies.com/how-to/content/how-to-calibrate-the-extruder-distance-on-your-3d-.html. That's how I came up with my number, and it seems to work fine!
