    I've read that E3D says you need a longer motor shaft for thicker brackets, but what exactly is the minimum shaft length for 2mm and 7mm brackets? I'm building my own bracket that I want to be as thick as possible (within reason), and am using an existing motor. I can't seem to find this data anywhere.

    I am interested in this also.

    I found the following comments in the Titan assembly instructions.
    1- Note that the motor offered on the extruder product page does not support spacing of more than 3mm since the shaft is not long enough to fully support the idler.

    It seems that the most common steppers we use have a shaft length of 24mm so the spacer can't be more than 3mm
