Hello,

I'm so frustrated with this darn printer I could scream. I've been trying to get it to work for a few weeks now and when I get one thing fixed another problem comes up. My current issue is the x axis is not homing. I click auto home and it moves a touch to the right and stops. When I check the M119 is says the endstop is triggered when it isn't. Please help. I'm at a loss.

Get your multimeter out and measure the switch, and also measure on the board.

If you measure across the switch you should get 0V when it's not triggered, and some volts when triggered. Same on the board.

Thanks for the reply. Yes we checked it with a multimeter and it appears to be working correctly electronically. It seems like something in the coding maybe but I can't find anywhere to check or change that.

What happens if you hold the switch down when homing?

If there's no change, then perhaps you got it connected wrong somehow?
Wrong port?

If it tries to home, then the switch is wired incorrectly, or you got the firmware wrong.
It should be wired as NC (closed when not pressed).

Edit:
That means I was wrong in my previous post.
You should have 0V when not affected, and volts when pressed.

In the Marlin firmware there is a setting for this: As I interpret this, is that when NC, set 'false', which is how I have mine set.

It was plugged in the max slot not the min. Got it fixed. Thanks.

You're welcome!
