Tevo Little Monster IR Probe Mount

Remove the BL Touch and replace it with an IR probe. The probe used is: https://www.filastruder.com/products/mini-differential-ir-height-sensor. To wire it easily, build a 3-pin to 3-pin servo cable and reuse the long 3-pin cable for the BL Touch. Move the single pin on that cable to the pin closest to the end stops on the same extension header - that would be pin 4.28. Update your configuration to set: https://github.com/crpalmer/kisslicer-configs/blob/master/tlm/smoothieware/config.ir. You can also remove all references to servo control from your config if you want to clean it up. Finally, change your start.gcode to do the z-probe like this: G1 Z50 F25000; move close to the bed G1 X25 Y13 Z3 F3000; move the probe to the middle of the bed G30 Z1.5; z-probe G1 Z4.5 F500 G30 Z1.5; z-probe G1 X0 Y0 Z100 F25000; move back away from the bed Where 1.5 / 4.5 (aka 3 + 1.5) are updated to reflect the right z-offset for you.
