Geetech Prusa i3 Pro A - Z Axis Problem!!

[johngomes]

Hello
I'm having problems with my Z Axis. It seems that sometimes one of the two motors is "stuck" and then only one of them moves,
so everything is getting messed up.
after a 10mm height of printing I measured the difference between the two motors and it reached up to 3mm.
By Stuck I mean that I hear like a weird clicking noise, it tries to rotate but not successful.
I did check the height of each motor at start (Home position) and it's the same position (0.1mm resolution caliper).

Hi,If you are referring to one of the z-axis motors being stuck,
You can check if your z-axis is at the same level;
Whether the coupling is installed correctly;
Whether the brass nut is too tightly installed can be adjusted properly;
For details, you can refer to this: http://geeetech.com/forum/viewtopic.php?f=82&t=60931



If it means that the motor can't work,
You can try to swap the motor wires of other axes with the motor wires that cannot run.
Determine if the motor line is broken.
