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

Last crawled date: 4 years, 3 months ago

NOTE If you are using any sort of metal clips to hold down your print bed (bulldog clips, etc) be sure to remove them and use tape instead. Either that or make sure to print without a skirt!
01 Jan 20: Changed square size for 0.8 and 1.0 nozzles to 40mm from 20mm. Doubles print time (around 20mins at 30mm/s print speed), but much cleaner results.
17 Jan 20: Added 0.6 nozzle file. Changed connecting lines to single nozzle width.
24 Jan 20: Added 0.2 nozzle file. Removed connecting lines.
27 Jan 20: Updated description.
Half-nozzle layer height to test level. 0.12 layer for 0.2 nozzle, 0.2 for 0.4 nozzle, etc...
My personal process is to first run the levelling gcode and then run this print. When the print is running I will adjust the nozzle height using Babystep Z (Tune>Babystep Z, or use the M290 command through terminal), and fine tune with the levelling knobs if I'm feeling really picky that day. You want to obtain the proper amount of "Squish" to get things to stick well. This is what things should/shouldn't look like. Here's another example. I will store this value in my print profile in Cura. Use the "Z-Offset" plugin from the Cura Marketplace. I personally use a 0.1mm feeler gauge to level things, so the Z-Offset will be just about that same value.
Tip: One full turn of the knob (M4 thread, 0.7mm pitch) moves that adjustment screw 0.7mm. From one knurl to the next is 0.05mm.
Then I run the other ones whenever I switch nozzles. I know my bed's tramming is correct but the z-offset may change with the nozzle change. I adjust for the other nozzle sizes with the Babystep Z feature as well. Once I figure out the general z-offset for different nozzle sizes after running these prints a few times, I will put that into Cura using the Z-Offset plugin.
