X axis not moving during homing

rhol1964

I am sure this is a configuration issue that I just cannot find. When homing all, my Z raises, my Y homes, my X moves about 10mm away from end-stop direction, Y homes again, BLTouch deploys probe, Z drops and BLTouch activates, then it just sits there. So the exercise here was to get dual Z working and BLTouch working. But somehow things have gone awry. Things I have tried, reading other posts, swapping cables on drivers and modifying config for those drives, trying a different motor on X, and trying a different cable on X.

Thanks in advance for taking a look

It sounds like the X axis endstop is triggered when it's not actually pressed. This could be a wiring problem or configuration problem.

Where is your X end stop physically located?

What kind of endstop is it?

Can you send M119 to check the status of your endstops?

@Phaedrux Hi and thanks for helping out. My X endstop is on the left side and is a physical switch, this is a converted Ender 3 V2. Ran M119 and got:

Endstops - X: at min stop, Y: not stopped, Z: not stopped, Z probe: not stopped

Next things I tried, plugged in a different switch to X endstop wire, same result as above. Swapped the endstop connection on the board and changed config.g to reflect that, same result as above. So, no matter if X is on io5 or io6 or on either switch I have X at min stop.

One other observation, should I have Z and Z probe showing in M119?

One last attempt, connected original switch to the old Z stop wire which is on io4 and changed the config.g to reflect that it belongs to X, reran M119, and X no longer reports at min stop, now reports not stopped.

I think this means that my wire may be bad, thoughts?

Phaedrux

Can you show the wiring of your x endstop switch at the board?

Phaedrux

Do you have a multimeter to check the continuity of the X endstop wiring?

rhol1964

@Phaedrux Yes I tested the outer pins on both of those connectors and they were both 47.1K Ohms. But I think I found the issue, when removing the X plug from the board, one wire pulled out of the connector but the pin remained in the connector. The wire was broken clean, I removed the pin and found a good crimp, it just broke off right through the insulation and the wire. Makes me wonder if these original Creality wires are at all trustworthy now, might purge these old wires from my setup. And on a good note, I was finally able to print an XYZ block!
