Wrong cube calibration 20x20x80

@chris4 I’d guess you’ve actually got 4-start, 8mm pitch leadscrew. Doesn’t really matter, just set M92 Z400.

Thanks ,
have tried with the M92 Z400 it too but it will be the same height on the Z axis.

Send M92 without parameters and check that the Z parameter it reports matches the value you have set it to. Changing the Z steps/mm from 1600 to 400 cannot fail to reduce the Z height by a factor of 4.

M92 without parameters

Should now try M92 without parameters in config.h

[chris4]

Homing failed without M92 parameters on config.h file, have tried to send M92 on G code but nothing happens

[chris4]

noticed that when I move Z axis +0,5 =2mm, +5 = 20mm, +25 = 100mm up is it correct?

M92 X160.00 Y160.00 Z1600.00 E837.08

Your M92 command in config.g file should looks like this M92 X160.00 Y160.00 Z400.00 E837.08

[chris4]

Have tried it with M92 X160.00 Y160.00 Z1600.00 E837.08,
but it will be the same

[dc42]

No, send M92 without parameters from the console. It will report the current M92 settings. Use this to check that the value that you think you have set in config.g is the value being used by the firmware.

It is same, if your Z value is 1600. You should change it to 400.

The answer from the console :
M92
Steps/mm: X: 160.000, Y: 160.000, Z: 1600.000, E: 837.080

And from config.h
M92 X160.00 Y160.00 Z1600 E837.08 ; set steps per mm

[Phaedrux]

Change your config.g

M92 Z1600 should be M92 Z400

[droftarts]

@Phaedrux that’s six times now we’ve told him to change Z1600 to Z400!

@droftarts Ten if you count the times I've shouted it at the screen.

How have you "tried" this? Have you changed your config file? Btw its config.g, not config.h

@chris4 Repeat - Change the M92 in CONFIG.G from 1600 to 400

[chris4]

@deckingman
As I had written earlier in posts I have tried with the Z400 in config.g
And it became the same height on the Z axis (80mm).
because you said, I have tested again and it became the same height (80 mm)
