A simple tool for easy and precise E-steps calibration on the Anycubic 4Max Pro.
Calibration procedure:
Heat up the nozzle to the standard temperature for the material used.
Insert filament into the extruder and push some through the nozzle to prime it.
Place the gauge over the extruder hole, stretch the filament and cut it flush with the top surface.
Remove the gauge.
Extrude a 100mm of the filament (use G1 E100 F100 command)
Place the gauge back and check the filament position:
the longest line is exactly at 100mm, the smaller lines are 1mm apart.

Calculate the actual extruded length:
if the end of the filament is for example 3 lines above the center line then the extruded length is 100mm - 3mm = 97mm
if the end of the filament is for example 5 lines below the center then the extruded length is 100mm + 5mm = 105mm

Calculate the new E-steps value and set it in the firmware.
Repeat 1-8 to check if the new value is correct or if it still needs some adjustment.
