Movement of x axis when Home

[Andreaprusai3prob]

Hi everyone. After assembling my i3 pro b I started using Repetier-Host (i use Mac). Despite various problems, I printed a small cube with poor results(it looks like a deformed parallelepiped), just to verify that the machine worked.
At the moment the main problem that I can not solve is that when I press the home command (from repetier or from the machine) the z axis rises upwards for about 4 cm. The other axis go home correctly, but not the z. Following old posts I opened merlin da Arduino and modified the values as instructions but without results.

Code: Select all

#define INVERT_X_DIR false    // for Mendel set to false, for Orca set to true
#define INVERT_Y_DIR false    // for Mendel set to true, for Orca set to false
#define INVERT_Z_DIR true     // for Mendel set to false, for Orca set to true
#define INVERT_E0_DIR false   // for direct drive extruder v9 set to true, for geared extruder set to false
#define INVERT_E1_DIR false    // for direct drive extruder v9 set to true, for geared extruder set to false
#define INVERT_E2_DIR false   // for direct drive extruder v9 set to true, for geared extruder set to false

Here are some suggestions:
1.Try to swap the A4988 of X axis and Z axis
2.I think we need to move your post to the correct section

hi, thank you, I tried to swap but my GT2560 Is pre assembled, I can't move them

Hi,

Does your pro B was expected to be equiped with a BL touch ?

When you move the head through Menu, Prepare / Move, are the movement coherent ? (increase X travel from left to right), increase Y move bed from back to forth, increase Z raise the head ?

[Andreaprusai3prob]

No I have not a BL touch.

Yes I can move trough printer menu and repetier host or cura, only movement i can not do is go down into the z axis (but I can ho upwards

If homing is not completed, it's normal that the printer refuse to let Z decrase (go down), principle being that absolute z coordinate could never be negative (it's set to 0 at current position at switch on)

I don't believe that you should reverse Z axis motor, if you menu/prepare/move z axis and increase value and the head go up, it's meaning that motor is turning in the right direction.

Could you check in your config.h file if the following command is present ? :

Code: Select all

#define BLTOUCH

At the same time, could you check that the z switch is correctly plugged to the board and that the two wire are clamped on the two switch extremities ?

[Andreaprusai3prob]

The command

Code: Select all

#define BLTOUCH

is not present.
The connectors of the Z axis seem to be inserted correctly in the card, I also tried to reverse them and reconnect, but the result does not change.

Could you forward a picture of board connection and micro switch connection ?

[Andreaprusai3prob]

I can not believe it, the problem was the stop z and y reversed, I was doing the photo and I came the doubt, my mistake, I thank you.
