Prusa i2 y-axis endstop hit problem

Hi guys,

I recently got a second hand Prusa i2 with a romscaj gen6 board. The problem is my Y-axis, when hit on the Y end stop, the motor keep turning. My x and z axis work fine. I wonder if anyone here have the same problem before and please let me know. Thank you very much!!

Here is my config h. code:

Hi,

I have same problem, i hope some can help.

Thanks,

John

how many endstops you have?one for each axis?
have you tried a different endstop to make sure it is functional?
have you tried connecting the endstop to the other pin?(there is one for max/min endstop functionality)

Hi eestudent,

Yes i've got a total of 3 endstops, one for each axis.
I've tried testing the switch functionality by switching it's pin with another axis and it is working fine.
However, i couldn't find the max/min pin on my prusa i2 (But there is on my i3).

Yup! i'm sure there will be!

Hi,

Finally, it works.

I made this config like this :

#define INVERT_X_DIR false // for Mendel set to false, for Orca set to true
#define INVERT_Y_DIR true // 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

// ENDSTOP SETTINGS:
// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1

#define min_software_endstops true // If true, axis won't move to coordinates less than HOME_POS.
#define max_software_endstops true // If true, axis won't move to coordinates greater than the defined lengths below.

// Travel limits after homing
#define X_MAX_POS 205
#define X_MIN_POS 0
#define Y_MAX_POS 166
#define Y_MIN_POS 0
#define Z_MAX_POS 180
#define Z_MIN_POS 0


and see the cabling for Y on this [www.youtube.com]

Im using Prusa I3 rework from replikeo

Cheers,

John

Hey john thanks for the code, i've tried but it didnt work.
Turns out there is a problem with my board, i went over to get a new one and its working fine now~
i saw the vid, nice vid btw~
