INDUCTIVE SENSOR RACK AND PINION - DRAKON EXTRUDER BODY

THIS IS A MANUAL ADJUST SENSOR CARRIAGE FOR AUTOMATIC BED LEVELING.

-THE MAIN PROBLEM I HAVE WITH AUTO LEVELING WAS THAT SOME TIMES MY BED (MADE OF 3MM PLYWOOD) WOULD POSSIBLY WARP.

-THIS ALWAYS MEANT I HAD TO REDO ALL THE ADJUSTMENTS BETWEEN THE X-AXIS AND THE SENSOR HEIGHT. I ALSO NEVER QUITE LIKED THE ADJUSTMENTS IN AVAILABLE IN THE FIRMWARE REGARDING SENSOR HEIGHT.

-THAT IS POINT OF THE RACK AND PINION CARRIAGE FOR THE SENSOR. TO DECREASE TIME SPENT ADJUSTING ANYTHING MECHANICALLY AND IN THE FIRMWARE/SOFTWARE.

-DECREASING THE WEIGHT AND SIZE WAS ALSO MY GOAL, TRYING TO KEEP THE SENSOR AS CLOSE TO THE NOZZLE AS POSSIBLE.

-YOU MUST SLIDE THE KEY ONTO THE ALLEN BOLT COMPLETELY.

-TIGHTEN 2 M3 NUTS SO THEY ARE SOME WHAT CENTERED RELATIVE TO THE RACK AND PINION GEAR.

-THE WAY YOU GET THE PINION ON IS TO TIGHTEN TWO M3 NUTS REALLY TIGHTLY WHERE THERE PROFILE MATCHES THEN THAT IS PRESSED INTO THE PINION.

-TIGHTEN THE LAST M3 NUT AGAINST THE OUTSIDE PROFILE OF THE CARRIAGE.

THAT SHOULD PROVIDE A TIGHT FIT FOR EVERYTHING AND BRING THE DISTANCE FROM THE EXTRUDER DOWN.
