My new screwless Z-axis: test of cord tension and hardness of pulley holders successfull
@shauki Iām not sure, if NEMA 17 have enough torque. Maybe, geared stepper are better. AWMR12 only for X and Y. The Z-axis have standard stainless rods.
my experience with z with belt are horrible need more torque of standard screw. i suggest to max tu use geared nema17 for heavy charge.
