PASO 34 Montaje de la(s) base(s) del soporte de bobina
Take the two BASE parts and insert the M3n nuts into the holes in both of them -
see the picture. If you can't push them in, insert a screw from the opposite side to
pull them in.
Flip one of the BASE parts and insert two bearings in it.
Put the second BASE part on top of the bearings.
Insert the M3x12 screw from the top and tighten it. Flip the base assembly over and
do the same.
Make sure both bearings can rotate freely. If not, release the screw(s) slightly.
Repeat this step for the second base assembly.
PASO 35 Añadiendo los railes del porta bobinas
Slide both rails in the first base assembly, use the grooves. Align the rail with the
edge of the base.
Secure the first base with two M3x8 screws. Use a reasonable force during the
tightening.
Slide the second base onto the rails. The exact position is not important at this
point - we will adjust it in the next step.
