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. It is modified for delta auto calibration, auto fan control, Neopixel LED strip, TMC2100(TMC2130 stand-alone mode), z-probe sensor, filament change. **You have to install Adafruit Neopixel library to Arduino IDE using Library Manager**, otherwise compile error occurs. I have set vref on TMC2130 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 value and try again. more accurate calibration: G33 P1 > G33 P2 > G33 P5 > G33 P10 sample output: "Height:323.16 Ex:-0.28 Ey:+0.00 Ez:-0.06 Radius:99.37 Tx:+0.25 Ty:-0.12 Tz:-0.13" Ex/Ey/Ez: endstop, Radius: DELTA_RADIUS, Tx/Ty/Tz: tower angle. 6. G33 P1(set height) 7. calibrate the z-offset remove the sensor. Then do the paper test and obtain the z-offset. g1 z20, g1 z0, g1 z-0.01 ...... set new z-offset: M851 Zxx.xx (old z-offset + z-offset) set new height: M665 Hxxx.xx (old height - z-offset) 8. M500 (store settings) 9. print the calibration circle and adjust the height again if needed change endstop offset: M666 Xxx.xx Yxx.xx Zxx.xx store settings(m500) I disabled G29(auto bed leveling) because it make things worse. **G33 Auto Calibration** https://github.com/FLSun3dp/FLSun-Kossel-Mini/wiki/02.-Calibrate-your-printer https://github.com/FLSun3dp/FLSun-Kossel-Mini/wiki/07.-G33-Auto-Calibration ** G29 vs G33 on Delta Printers** https://hennerley.wordpress.com/2018/01/29/g29-vs-g33/ --- **펌웨어 설명(modified firmware guide)** https://goo.gl/H1aY29 --- ** Anycubic Kossel Upgrade ** Part 1 - Neopixel LED - https://goo.gl/9pQQsS Part 2 - TMC2130(TMC2100), Cooling Fan - https://goo.gl/c7NZbk Part 3 - Magnetic Bed - https://goo.gl/5rvKeF Part 4 - Power Modify(Cooling Fan, add Register, XT-60 connector) - https://goo.gl/KwQwqR Part 5 - Aluminium Carriage, Corner Bracket, etc - https://goo.gl/3wuJzQ --- **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 - changed 'DELTA_HIEGHT', '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 - 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)
