Hi all!
I am new to this area, and i dont have experience with parts of cnc
we take some cnc machine for hot wire cutting, milling styrofoam
all works fine when machine use hot wire for cut
but when we mount 3rd Z axis (rods, threaded rod, holder and milling AMB 1050W) all together is about 7-8kg maybe more
then machine doesnt work well
sometimes left stepper motor seams like dont have enough power to lift Z axis, z axis have 2 step motors for left side and right side
it is possible that step motors are to weak to lift all z axis parts
motors are ACT 23HS8430
also if a little bit of milling dust falls on Z-axis rods and threaded rod machine stops working, goes out of sync and does not make what should do
thank you
