Bed Level Squares for 235mm Beds: 0.2, 0.4, 0.6, 0.8, and 1.0mm nozzles

Human: **WARNING** If you're relying on metal clips to hold down your print bed (bulldog clips, etc.), make sure to remove them and switch to tape instead. Alternatively, ensure you print without a skirt! 01 Jan 20: Updated square size for 0.8 and 1.0 nozzles to 40mm from 20mm. This adjustment doubles print time (approximately 20mins at 30mm/s print speed), but yields significantly cleaner results. 17 Jan 20: Added 0.6 nozzle file, incorporating single nozzle width connecting lines. 24 Jan 20: Introduced 0.2 nozzle file, eliminating connecting lines in the process. 27 Jan 20: Enhanced description for clarity. To test optimal layer height, use half-nozzle settings. For example, set to 0.12mm for a 0.2mm nozzle or 0.2mm for a 0.4mm nozzle and so on. My personal procedure involves running the [levelling gcode](https://www.thingiverse.com/thing:4091791) first, followed by this print. While printing, I adjust the nozzle height using Babystep Z (Tune>Babystep Z, or employ the [M290 command through terminal](https://marlinfw.org/docs/gcode/M290.html)), and fine-tune with levelling knobs for precision. The goal is to achieve the perfect amount of "Squish" to ensure proper adhesion. For reference, consult these images: [This is what things should/shouldn't look like.](https://blog.prusaprinters.org/wp-content/uploads/2018/04/first_layer.jpg) [Here's another example.](http://i.imgur.com/XiPmH3Z.jpg) To store the optimal Z-Offset value, use the "Z-Offset" plugin from the Cura Marketplace in your print profile. I personally utilize a 0.1mm feeler gauge for levelling, so the Z-Offset will be approximately that same value. Tip: One full turn of the knob (M4 thread, 0.7mm pitch) moves the adjustment screw 0.7mm, while one knurl to the next represents 0.05mm. [This visual aid](https://i.redd.it/fnm6v5y7n6c41.jpg) helps illustrate this concept. After determining the general Z-Offset for various nozzle sizes through repeated testing, I will incorporate that information into Cura using the Z-Offset plugin.
