Homeing issue

[LindaJ]

Hello

I hope I can get help.

I have a fully assembled rostock mini from geetech using repetier. I uploaded the latest firmware and the machine seems to be properly assembled.

When I click to HOME and I place the spider at the middle of the rods, X and Y finds home with no problem but Z only moves up a little. if I week pressing HOME until Z reaches the stop sensor, it jams.... the Z motor wants to keep going up and pushes the stop sensor.

The manual is very bad and after this part I cant get it to move.

also. The fan of the heating element does not turn on. IF I plug it to another fan it works, but on the port where the manual tells me to install it the fan does not run.

please help!

Thank you

“the Z motor wants to keep going up and pushes the stop sensor”
Did you check the wire of the Z axis endstop sensor? Are they correct conected ?
