CR10S PRO Z axis only goes up before printing

What is the problem?
When I want to print any part the printer starts to do the automatic leveling but after doing the X / Y Home it starts doing the Z Home and the Z axis just goes up and does not stop going up instead of going down as it does Normally, if I do not connect it to Octoprint and if I do not turn off the printer manually, the Z axis goes off the rails. Could you please tell me if I am the only one to whom this happens?

I leave the snippet of text that I see in the "terminal" of octoprint if you see any error there.

thank you!!
What did you already try to solve it?

Recv: echo:busy: processing
Printer seems to support the busy protocol, will adjust timeouts and set busy interval accordingly

The command "Recv: echo:busy: processing" is because I have to turn off the printer y that moment

Hi Auke, I solved it doing a Z Home in the leveling menu before printing, if a connect for the first time the raspberry to the Cr10s pro and don't do that I always have the same issue. Try this and tell me if run or work for you! I hope so... Best Regards!
