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

Last crawled date: 3 years ago

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.
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.
M502 (factory reset)
M500 (store settings)
M503 (get current settings)
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.
G33 P1(set height)
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)
M500 (store settings)
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.
