Anet A6 - Frankenstein IR sensor mount (auto leveling)

thingiverse

This is a sensor mount for David Crocker's mini height sensor board. You can find the details here: https://miscsolutions.wordpress.com/mini-height-sensor-board/ The sensor mount is positioned on the back of the Frankenstein and replaces the small X axis limit switch holder, which is integrated here. The sensor board is mounted on the inside of the mount with its back facing towards the nozzle. **08/09/17 - new Version v2:** - back parts thickened for better stability - moved sensor 5mm further towards the nozzle (now it should be 33mm behind) - removed endstop mounting plate (not used on my printer, because the endstop switch is mounted on the left side of the x axis Setup parameters =============== Z Probe offset in Marlin ----------------------------- You have to modifiy the probe position in your Marlin source accordingly. This mount positions the board directly behind the nozzle, so - X_PROBE_OFFSET_FROM_EXTRUDER should be 0 (from David Crocker's page: "The sensing area is approximately in the middle of the bottom edge of the board, below the cylindrical capacitor.") - Y_PROBE_OFFSET_FROM_EXTRUDER should be somewhere in the range of 30 to 35 mm (positive values = behind the nozzle) Z Probe bed position -------------------------- As the probe is exactly behind the nozzle you should be able to take measurements relatively close to the right and left edge of the hotbed. Perhaps values like - LEFT_PROBE_BED_POSITION 15 - RIGHT_PROBE_BED_POSITION 205 should be fine. For the front you need to take into account, that the sensor is *behind* the nozzle, so if the nozzle is at 0, the sensor is round about at 30 or so. You can perhaps try it with - FRONT_PROBE_BED_POSITION 45 The back position is opposite to the front, so perhaps you start with somewhat like - BACK_PROBE_BED_POSITION 175 ***FOR SURE YOU HAVE TO FIND OUT THE EXACT POSITIONS ON YOUR OWN. I can't be held responsible if anything goes wrong! Just be warned ;-)***
