m119 Endstops - X: at min stop, Y: at min stop, Z: no endstop, Z probe: not stopped

this is when they are not pressed

@phaedrux

Okay. Thanks. Here is a photo.

@gixxerfast

Yes so with or without the "^" the "!" works. But now I ran into the other issue of the end stops reading properly. I guess the next step is to check the wiring on those and see what I can do. Thanks for your help on this. Hope you had a good weekend.

@gixxerfast

I think you are correct. Without hitting either of the stops M119 reads:

m119 Endstops - X: at min stop, Y: at min stop, Z: no endstop, Z probe: not stopped

Edit:

I read another discussion and found this would finally work to get the print head to move towards the end stop... but the endstop pin is still not being recognized.

So after much etsting I realized that the printer is not reading the homex and homey correctly. It completely skips the "H1" commands. For example:

G1 H1 X-240 F3000 ; move quickly to X axis endstop and stop there (first pass)

Therefore, it never actually homes x and y to the endstop pins. I tried to change it to H2

e.g. G1 H2 X-240 F3000 ; move quickly to X axis endstop and stop there (first pass)

and it worked, however, it does not recognize the endstop pin. I'm stuck again. Any help here is greatly appreciated as always. Thank you.

G1 H2 Z5 F6000    ; lift Z relative to current position
G1 H1 X-240 F3000 ; move quickly to X axis endstop and stop there (first pass)
G1 H2 X5 F6000    ; go back a few mm
G1 H1 X-240 F240  ; move slowly to X axis endstop once more (second pass)
G1 H2 Z-5 F6000   ; lower Z again
G90               ; absolute positioning

@gixxerfast

Instead of the print head moving toward the endstop pin... it travels to the right.. away from the pin.

Edit:

Can you send me an example of what that would look like... as far as separating the x and y and z?

@phaedrux

confirmed. When i go to MOVE on my display if I hit +1 the x axis moves rights. However, you were correct. The y-axis was moving the wrong direction. Here's the format I think you were referencing.

So I changed the config.g 569 to match this and now all is moving in the correct direction.

M569 P0.0 S0                                       ; physical drive 0.0 goes backwards
*M569 P0.1 S1                                       ; physical drive 0.1 goes forwards*
M569 P0.2 S1                                       ; physical drive 0.2 goes forwards
M569 P0.3 S0                                       ; physical drive 0.3 goes backwards

Edit: I also changed the homey. Is this correct?

G91               ; relative positioning
G1 H2 Z5 F6000    ; lift Z relative to current position
G1 H1 Y-240 F3000 ; move quickly to Y axis endstop and stop there (first pass)
G1 H2 Y5 F6000    ; go back a few mm
G1 H1 Y-240 F240  ; move slowly to Y axis endstop once more (second pass)
G1 H2 Z-5 F6000   ; lower Z again
G90               ; absolute positioning

@phaedrux Sure.

On the ender 3 the x-axis endstop pin is located on the far left of the x-axis. The y-axis is located at the back of the printer next to the y-axis stepper motor. I believe I have it set at low end for both when I configured the file using the RepRap tool.

So if I changed the direction in 569 for both the x and y-axis motors... what others changes would be needed to get it to g28 in the right direction?

@gixxerfast Yes. Z-axis moves well.

@gixxerfast

Okay. I was able to get it to run G28. However, another issue. Maybe you can help me with this as well. I had to switch the direction of the x and y axis motors in config.g. (I replaced the x axis motor with a high torque motor from e3d).

When I enter G28 the extruder travels in the wrong direction. Instead of going towards the pin, it travels the opposite direction. How can I fix the homing files to compensate for this change? I will attach my config.g and homeall
