Problem of Mendel axis

Hello
has all I dashed too into the construction of Mendel
no concerns of assembly because she is finished completely
only I have about concerns everything axes strengths by moving it (engines do not move them)
I have loosened the bearings in the case or he would force too much on bars but nothing it made
I have put any young few oil on bars so that that slides but always have nothing you an idea of or that can come ?
Thanks
sorry for my bad english but im french

Hello,

- what electronics?

- what stepper motors?

- have you verified your stepper motors connexions? do they turn with no load?

- have you adjusted your steeper driver potentiometers?
