Poorman Unlevel Bed Compensation unit V2 Update 5-6-2017 Where some like to use the ANTCLABS BLT, some dislike it. Pricewise the BLT is more expensive. The UBC version you see here is cheap, very cheap and the fun of it all you can adapt it for almost every machine not only the Tevo Black Widow. Some features over other UBC devices: 1] it can be used on all bed surfaces (no exclusions). 2] it is not prone to temperature changes in the room or bed. 3] what you see is what you get during the working and setup. 4] High accuracy and repeatability (better then.......:-) ) 5} Lowest price possible with ready to buy products. There are two versions in the files. One for the Titan extruder One for the STOCK BW extruder The sensor activator works for both versions. Both have premade support added. Only print the sensor activator with black filament ( do not use light colors or translucent ) Sensor: 5 volt optical 3D endstop sensor. The pin that guides the sensor activator is 2 mm but the holes in the sensor activator and the housing can be drilled to 3 mm maximum in size. The example uses a 2 mm carbon pin. Servo's: The set up uses a HXT500 servo and has screw holes to fix the servo. In Marlin set the servo values 90 for down and 130 for up as a guideline or adapt them if needed. Measured deviation 0.003 mm average. Servo cost +/- 3 Euro Sensor cost 1 Euro Extra hardware: Need one M3 x 10 mm screw to secure the pin to the sensor activator. Need two M3 x 8 mm screw to attach the sensor to the housing. metal pin 2 or 3 mm.
