The attached files are my personal 3D printer calibration tests that I use to calibrate my Ender 3 V2. I couldn't find any relevant test files that did the calibration steps that I wanted when I first started printing so I used some of the CHEP's original g-code and modified the files. Specifically CHEP's original (CHEP_bed_level.gcode) bed level g-code does not pause on the Ender 3 V2. I have listed the links to CHEP's original files and descriptions, in order, for each file below.

V2_movement_test.gcode
This file moves the Z-axis, X-axis, and Y-axis on the Ender 3 V2. I use this to make sure there is no binding, grinding, or hang ups when moving the extruder or bed on my V2.

V2_bed_level.gcode
This file is the modified version of CHEP's bed level g-code and it moves the nozzle to all four corners of the print bed. I corrected the Z-axis pause points to be directly over the adjustment screws and also fixed the pauses so the Ender 3 V2 actually stops at each point. CHEP's original code doesn't line up on the V2 threads and just keeps moving without any pauses as its specific to the Ender 3 printer only.

CHEP_bed_level_print.gcode
This file is CHEP's original bed level print and prints out concentric squares to test that your prints stick to the bed platform appropriately. CHEP has a video on how "tight" they should be stuck to the bed and can be found on his page.

CHEPCube.gcode
This file is my final calibration print and I use it as a benchmark to make sure my printer is calibrated properly. If this 20x20x20mm cube comes out with anything other than +/- 0.1mm in any direction then that tells me I need to recalibrate my machine or adjust one of my axis points.

I hope you find these calibration steps helpful when calibrating your Ender 3 V2.
