Marlin Autoprobe checklist

I don't think my RichieC Marlin's Auto calibration is set up correctly. Can someone running me through the process.

I'm running RAMPS 1.4. I have a micro switch connected to Z-Min (pin 18) Not sure if it is NO or NC. How can I reverse it in the firmware?

Do I need to comment or uncomment anything in Configuration.h or pin.h? Or am I ready to go with my basic motherboard 33 set?

I know I have to set the probe offsets etc. but not sure if anything else inpin.h needs alterations.

Thanks

Hi Disneytoy

Use M119 to determine the state of your Z probe microswitch. It should be 'open' when the probe is deployed but not touching the bed and change to 'triggered' when the probe touches the bed. If you need to change it look for this line in your configuration.h :-

const bool Z_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop

Change the 'false' to 'true' or vice versa to alter the endstop logic. In order for the probe software to work you also need to disable the X and Y min endstops. Do this by editing pins.h. You need to find the pin definition section for your motherboard and make the definition for both these endstop pins -1

Good luck

Thank you!

Hi Gang!

I'm trying to test my autocalibration switch. I have a simple microswitch wired to my Ramps 1.4 I'm connected to Pin 18. I've tested my wiring with a multimeter to it does work.

I use M119 to test my switch, But I only get:

01:23:32.110 : Reporting endstop status
01:23:32.110 : x_max: TRIGGERED
01:23:32.110 : y_max: TRIGGERED
01:23:32.110 : z_max: TRIGGERED

Not reporting Z_min?

I checked my Pin.h and it looks good. Do I have anything mis-configured for my probe?

Thanks

My old Marlin configuration.h file has this little gem hidden inside it:

// Deltas never have min endstops
#define DISABLE_MIN_ENDSTOPS

Since M119 isn't showing the MIN endstops, I'm guessing that yours has the same setting not commented out. Put a double slash in front of it (to comment it out) and see if M119 shows all six endstops.....

Thank you. You were correct sir!!!

Thanks vreihen, I was trying for 2 days now to get autolevel to compile correctly. This should be disabled by default for the delta examples.
