endstop status check

[Toy]

If you've met some troubles about homing, then usually it's the problem of endstop.

Note that, you need to home the printer after you start it or you'll get wierd behaviors such as crash to the bed, move only in one direction, etc.

For other printers,
Make sure the wire is corrected to pin1 and pin2

If you find a endstop doesn't work, you can plug it to other axis, see if the endstop is defective.

You can also use M119 code to check if the endstop works.
Homing the printer first, and use M119 to check the endstop status. If the printer can not home itself, you can manually trigger the endstop one by one.

Then you'll get

18:10:11.392 : y_min: TRIGGERED
18:10:11.392 : z_min: TRIGGERED

Then move the extruder from the endstop, send M119, and you'll get
18:16:55.066 : x_min: open
18:16:55.066 : y_min: open
18:16:55.066 : z_min: open
