I din not found broken bike chain, but i found these 2 pieces from old tries. Al & brass, in the middle the bic gear. Asfaics, i get contact only on one bearing. By hand works like wooow. Curious regarding the returning bearing. The brass will get cut& 2 m3 small screws. Any tips?
Thx Max . How do you do the tensionon fillament?
Shauki, i checked the tension& the angle between surface & motor axle tangent…
@Darkberg_Aryavis adjust the distance between mk8 and bearing to 1,5mm. no springs-no problems .
On delta also
@shauki Yes, but plastic parts works like springs. is too complex for me.
