====== Anycubic Kossel Plus ====== ===== BL / 3D Touch Setup ===== ==== Hardware ==== - Print bracket such as: http://www.thingiverse.com/thing:2251115 - Connect White/Black wire to z-min-endstop (S = (signal - white), - = (minus - black)). Orientation doesn't matter - Connect Brown/Red/Orange wire to servo 0 port (S = Orange, + = Red, - = Brown) NOTE: on the Tri Gorila Board + and - are reversed. {{::20170513_152037.jpg?direct&300|}}{{::20170513_164053.jpg?direct&300|}} - Powering on system should make LED light red and move the pin a few times ==== Software (Marlin) ==== Using release from Anycubic: https://drive.google.com/drive/u/0/folders/0B8VIB533cgdMa1czMW5hNWlXYW8 Some of these may already be set. #define MOTHERBOARD 43 // using 33 doesn't work #define BLTOUCH // turn on probe // these values strongly depend on your mount! #define X_PROBE_OFFSET_FROM_EXTRUDER 36.1 // X offset: -left +right [of the nozzle] #define Y_PROBE_OFFSET_FROM_EXTRUDER -29 // Y offset: -front +behind [the nozzle] #define Z_PROBE_OFFSET_FROM_EXTRUDER -3.6 // Z offset: -below +above [the nozzle] #define XY_PROBE_SPEED 6000 #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN #define Z_CLEARANCE_DEPLOY_PROBE 50 // Z Clearance for Deploy/Stow #define Z_CLEARANCE_BETWEEN_PROBES 10 // Z Clearance between probe points #define AUTO_BED_LEVELING_BILINEAR // works better but still not ideal #define SAFETY_MARGIN 5 #define DELTA_PROBEABLE_RADIUS (DELTA_PRINTABLE_RADIUS - sqrt(sq(X_PROBE_OFFSET_FROM_EXTRUDER)+sq(Y_PROBE_OFFSET_FROM_EXTRUDER)) - SAFETY_MARGIN ) // #define DELTA_PROBEABLE_RADIUS (DELTA_PRINTABLE_RADIUS -10) #define LEFT_PROBE_BED_POSITION -(DELTA_PROBEABLE_RADIUS) #define RIGHT_PROBE_BED_POSITION DELTA_PROBEABLE_RADIUS #define FRONT_PROBE_BED_POSITION -(DELTA_PROBEABLE_RADIUS) #define BACK_PROBE_BED_POSITION DELTA_PROBEABLE_RADIUS ==== Test the probe works ==== Send G codes ''M280 P0 S10'' and ''M280 P0 S90''. Probe should extend on first command and retract on second. ==== Finding probe to hotend offset (Marlin) ==== - make a mark on the bed with a pen or sticker - Move the hotend to this exact location (use G codes, e.g. ''G1X10Y-10Z10'' moves the probe to X +10mm, Y -10mm and Z +10mm) - Put a paper under the probe and move it until the paper sticks a bit. Use ''G1Z5'', ''G1Z4'' etc. until you reach the paper - Reset all values to Zero: ''G92 X0 Y0 Z0'' - Move the hotend off the mark ''G1Z10'' - Now move the probe exactly over the mark using G codes like above - once you are exactly on the mark extend the probe with ''M280 P0 S10'' (if the probe doesnt move reset it with ''M280 P0 S260'') - start lowering the probe slowly using ''G1Z9'', ''G1Z8'' etc. once you are close start adding decimals - when the probe activates note down the numbers on the LCD. - In my case I had ''X-36.1 Y 29 Z 3.6'', now enter the offsets in Configuration.h (NOTE: X shows a negative, that means enter it possitve in Marlin, Y is entered as a negative. ) ==== Trigger Auto Leveling ==== - Enable logging to see what is going on ''M111 S247'' - Zero Z, using ''G28'' - Level Bed ''G29'' (use ''G29 V4'' to see more log info) ==== Update Slicer ==== - In your slicer make sure you set the printer to do a ''G28'' then a ''G29'' before each print. NOTICE: Doing a ''G28'' resets the autolevel values! I am still trying to figure out how to get Octoprint to not reset my auto level values before printing.
