Received a 3-D Printer on 12/31/2020:
Creality Ender 3 V2 Upgraded 3D Printer with Silent Motherboard Meanwell Power Supply Carborundum Glass Platform and Resume Printing 220x220x250mm
From Amazon
Leanne and I put it together, and it successfully printed the “dog” test print. We had to adjust the Z-Axis switch up and down so that the bed would be in an adjustable range to level with the corner adjustment wheels. We printed the test print, although it still isn't completely level at the front left corner.
The 3-D Printer came with a Micro SD card, as well as a USB-to-MicroSD converter. This card had two sample gcode files (a dog and a cat model). I copied this to F:\download\Creality

The language that is sent to 3-D printers is GCODE. These are a list of G-commands in a text file.
They are generated by “Slicer” programs such as Cura and Simplify3D. These generate G-code “automagically” from CAD models, so most users never see or program a single line of code.
Had best success by not using the “Disable Steppers” function. Then I used tips from this web site:
Files: LevelBed_NRML_GCODE_file.gcode, LevelBed_CNTR_GCODE_file.gcode
The idea is that if you Disable Steppers, the print head can move vertically while trying to move it around, causing it to become out of adjustment.
Also there was a gcode file which helps by moving the print head to Z=0, and right over the adjustment “wheels” one at a time. The person on the web site points out that some gcode actually moves to Z=0.2, which throws off the adjustment.
This has been working fine. I adjusted the bed today 5/18/2021 to print something which fills the bed, and the corners were off.
Had problem where the filament came out a bit whispy, and it wouldn't stick to the bed. Tried doing a LevelBed_CNTR_GCODE process moving the nozzle closer to the glass without improvement.
Used new needles to clean out the nozzle. The new needles are a bit larger in diameter (although shorter), and fit tighter in the nozzle orifice, perhaps cleaning it out better. 7/11/2023
