Extruder wheel and L-shape bracket 3.1. dual

[Brico]

Hi
it's about the 3.1. dual extruder:
the M3x4 screw that hold the extruder wheel (pulley) on the motor is too long. The motor can not turn as the screw touches the L-shaped bracket (assembly step 44 and following). Once the screw is in place, it has to be filed down flat before mounting the L-shaped bracket.

Did you adjust the position of the pulley so the screw was going against the flat part of the shaft? I could see what you're describing happen if you were inserting against the round part.

Hi Kerog
thank's, but yes, the screw got aligned to the flat part. It's not the first printer I assemble.

Well, I assembled two Felix 3.1 upgrades and didn't have any problem with either...
