I can not move manually the motor in CW but the printer works, why?

Here is the place to discuss software and related tools for Slice generation, machine control, & etc...

hi folks, i would like to move the motor of the Z axis through the CW tool for homing the build plate, but unfortunately nothing works, i can not figure out why, in fact my 3d printer is working almost good, the commands sent by a clik are not executed by the motor!
WHY?!?!?!?!
thank you in advance.

Couple if things:

First couple are a bit obvious but make sure you've hit the connect button... Then in the control screen motors are turned on.

After that the biggest thing I can think of is on my machine the platform will only move up until I home the z axis to the limit switch at the top

Yes, connecting the machine the motor moves but it not do only 10mm but it start moving without stopping. Another problem is tha during the preinting the built plate does not move 5mm as i choosed and set in the arduino code, it moves down 1mm independently by my settings. I really dont know where modify my system.

What electronics (board and stepper drivers) and what firmware?

if your screw is a 10x3 it should move 3mm for every rotation or 3.33 revs per 1cm.

I'm not familiar with using that firmware. You might look at changing to marlin or which can be setup pretty easily then you will be able to set layer heights and lift parameters in CW and not have to change your firmware to do so.

ok, now i will lokk how to move to another sw. does Marlin requires a particular hardware? i have an arduino and some custom electronics so i prefer to mantain my boards.

Marlin works on arduino. You can choose from one of the preset 3d printing boards then match the pins for your stepper driver to that.

And what about creation workshop + GRBL?? I prefear GRBL because i can also use the board to drive a hipotetyc CNC or 3 axis system.
Do you think that i have to do some modifications to CW to make a correct connection with GRBL.??
