Question Problem with the Z axis.

First of all,
hello to all the users and administrators of this forum.
This is my first post.

I just finished the assembly of my Stepcraft-2/600.
Everything seems to be ok except the Z axis. Some times it goes up others it goes down with the same fast button pressed on the WinPC-NC, and when I press the slow button for up or down the motor shake and makes erratic movement, does not move continuously on any direction.

Any suggestion?

Regards

Hello Fernandes,
the cause is probably a problem contact or loose contact of the lines of the stepper motors. Control the Z lines if they have all good contact.

Cordialmente,
Helmut

Hello Mogul,
Thanks for your advice.
After checking and rewiring all the conections, the problem was solved. I already made the first engraving test from the Getting Started Manual and worked fine.

Thanks a million Mogul,
you saved my day.
