/** /**
* Z Probe to nozzle (X,Y) offset, relative to (0, 0). * Nozzle-to-Probe offsets { X, Y, Z }
* *
* In the following example the X and Y offsets are both positive: * - Use a caliper or ruler to measure the distance from the tip of
* the Nozzle to the center-point of the Probe in the X and Y axes.
* - For the Z offset use your best known value and adjust at runtime.
* - Probe Offsets can be tuned at runtime with 'M851', LCD menus, babystepping, etc.
* *
* #define NOZZLE_TO_PROBE_OFFSET { 10, 10, 0 } * Assuming the typical work area orientation:
* - Probe to RIGHT of the Nozzle has a Positive X offset
* - Probe to LEFT of the Nozzle has a Negative X offset
* - Probe in BACK of the Nozzle has a Positive Y offset
* - Probe in FRONT of the Nozzle has a Negative Y offset
*
* Some examples:
* #define NOZZLE_TO_PROBE_OFFSET { 10, 10, -1 } // Example "1"
* #define NOZZLE_TO_PROBE_OFFSET {-10, 5, -1 } // Example "2"
* #define NOZZLE_TO_PROBE_OFFSET { 5, -5, -1 } // Example "3"
* #define NOZZLE_TO_PROBE_OFFSET {-15,-10, -1 } // Example "4"
* *
* +-- BACK ---+ * +-- BACK ---+
