I bought myself a A10 3D printer.
I builed it but I've a problem, when connecting with Repetier-Host (Following the User Manual provided by Geetech on this website)
I can use in manual control the set home button but when I try to move it manually the motor starts vibrating.... So emergency stop

I upgrade the firmware to the last version (provided by the user manual) but same prolem happened.
I downgrade Repetier host to 2.0.5 but also the same problem. The Baud rate is the same between Repetier and the firware.
Thank you in advance.
