Marlin 1.1.8 firmware for Anycubic Kossel(mini & plus), delta calibration circle

thingiverse

Marlin 1.1.8 firmware for the Anycubic Kossel(mini & plus) Delta Printer. This modified firmware is designed for delta auto calibration, auto fan control, Neopixel LED strip, TMC2100(TMC2130 stand-alone mode), z-probe sensor, and filament change. To compile this firmware successfully, you must install the Adafruit Neopixel library in your Arduino IDE using the Library Manager. Failure to do so will result in a compilation error. The vref on TMC2130 has been set to 1v. Use at your own risk. Delta Auto Calibration using LCD controller(without gcode) https://youtu.be/U20_2BkuD4g Delta Auto Calibration Steps(with gcode) Clean the nozzle and install the sensor. Run Pronterface and send the commands. 1. M119 (check sensor status) Execute M119 while pressing the sensor. If everything is set up correctly, you will see 'z_min: TRIGGERED' message. If the status(open/triggered) is reversed then change the values of '#define Z_MIN_PROBE_ENDSTOP_INVERTING' and 'Z_MIN_ENDSTOP_INVERTING' in Configuration.h to false. 2. M502 (factory reset) 3. M500 (store settings) 4. M503 (get current settings) 5. G33 (auto calibration) If you see 'Probing failed' message after going down to the bed, change the 'DELTA_HEIGHT' value in Configuration.h to a larger number. 6. G1 F1500 X100 Y100 7. G28 8. G29 Repeat steps 5-8 until the print head reaches the home position and the probe is triggered. Delta Calibration Circle: The calibration circle has been redesigned to reduce printing time. Configuration changes for kossel mini: - changed 'DELTA_HEIGHT', 'DELTA_RADIUS' of kossel mini - changed 'DEFAULT_MAX_FEEDRATE' of extruder to '50' - changed 'DEFAULT_RETRACT_ACCELERATION' to '400' (TMC2100) - changed 'Z_PROBE_SPEED_SLOW' to '(Z_PROBE_SPEED_FAST / 3)' (more slow calibration) - changed 'NOZZLE_PARK_POINT' of z to '30' - changed 'NOZZLE_PARK_Z_FEEDRATE' to '100' Configuration_adv changes for kossel mini: - changed 'EXTRUDER_AUTO_FAN_SPEED' to '255' - changed 'DEFAULT_STEPPER_DEACTIVE_TIME' to '0' (disabled) - changed 'FILAMENT_CHANGE_UNLOAD_FEEDRATE' to '25' - changed 'FILAMENT_CHANGE_LOAD_LENGTH' to '50' - changed 'ADVANCED_PAUSE_EXTRUDE_LENGTH' to '30' - changed 'PAUSE_PARK_NOZZLE_TIMEOUT' to '600' - enabled 'PARK_HEAD_ON_PAUSE' Changelog: 2018/5/4 - changed 'DEFAULT_XXX_ACCELERATION' of TMC2100 to '800'. The print speed will be increased. - changed 'SD_FINISHED_RELEASECOMMAND' to raise print head when stopping print job. 2018/4/3 - redesigned calibration circle to reduce printing time Configuration.h changes: - changed 'DELTA_HEIGHT', 'DELTA_RADIUS' of kossel mini - changed 'DEFAULT_MAX_FEEDRATE' of extruder to '50' - changed 'DEFAULT_RETRACT_ACCELERATION' to '400' (TMC2100) - changed 'Z_PROBE_SPEED_SLOW' to '(Z_PROBE_SPEED_FAST / 3)' (more slow calibration) - changed 'NOZZLE_PARK_POINT' of z to '30' - changed 'NOZZLE_PARK_Z_FEEDRATE' to '100' Configuration_adv.h changes: - changed 'EXTRUDER_AUTO_FAN_SPEED' to '255' - changed 'DEFAULT_STEPPER_DEACTIVE_TIME' to '0' (disabled) - changed 'FILAMENT_CHANGE_UNLOAD_FEEDRATE' to '25' - changed 'FILAMENT_CHANGE_LOAD_LENGTH' to '50' - changed 'ADVANCED_PAUSE_EXTRUDE_LENGTH' to '30' - changed 'PAUSE_PARK_NOZZLE_TIMEOUT' to '600' - enabled 'PARK_HEAD_ON_PAUSE' 2018/3/13 - enabled 'ADVANCED_PAUSE_FEATURE' - changed 'DEFAULT_STEPPER_DEACTIVE_TIME' to 300 To change filament while printing, go to 'tune>change filament'. 2018/3/2 - changed 'DEFAULT_RETRACT_ACCELERATION' of TMC2100 to '200' - redesigned the delta calibration circle 2018/2/28 - changed the z-offset of piezo sensor to '-0.07' 2018/2/26 - added firmware for Anycubic Kossel Plus 2018/2/24 - changed the z-offset(Z_PROBE_OFFSET_FROM_EXTRUDER) of anycubic leveling module to '-14.9' default z-offset of anycubic leveling module v1 is '-18.0' and v2 is '-14.9' You need to adjust it for your printer. - disabled calibration H_FACTOR,R_FACTOR,A_FACTOR. - changed HOMING_FEEDRATE_Z to (50*60)
