New problem with the new M200.
It seems that the z-axis motor has lost its torque.
It can move downwards when I give the order "move 5mm down", but when I select the opcion "move 5mm up", it doesn't move (unless I push up with my hand).
The platform is not blocked, since I can move it manually with M200 disconnected, and I can also turn manually the spindle with two fingers and any effort.
If I try autocalibration, it doesn't work. And It can also not print.
Probably it is related to this issue:

Im not shure, moving the platform up manualy ([Move platform 5mm UP]) does not stop even if the endstops reach. You can crash the platform into the nozzle easily
Thanks for your answer,
But I think that it is not problem of the 3-pin connector. It seems to be OK, and the behaviour of the platform is the same when the connector is disconnected.
Before turning the M200 on this morning, I sprayed the aluminium plate with hairspray in order to fix adherence problems (according to several advices that I read in this forum). I have thought that the hairspray could have short-circuit any circuit in the platform. So I cleaned the plate with acetone, but the problem persisted.
I think that exist the possibility that the coupling between the z-axis motor and the spindle is loose. A subtle buzz from the motor can be heard when I give the order do move up 5mm, so it makes me think that the motor is turning. But to check it I should disassemble the chassis and I am afraid that this would void the warranty...
The problem was solved replacing the motor. Our reseller did it quickly.
