Wanted Nema 17

Big ask I know, but I have just got my first 3D printer (kossel mini from think3dprint3d)
assembled it over the last two nights. Went through the calbration, got to the last stage of getting the extruded calibrated and the motor is faulty! Noisy and sticking. 100 mm at 100mm/s pulls through between 30 and 60 mm totally inconsistent.

now if anyone has a motor spare
and they live in London
and they don't mind me picking it up tomorrow (Sunday 29 November)

call me on 07702000125

cash waiting

thanks in advance!
