Prints 1 layer high @ 0.3mm height with 4 perimeters which will give you all the info you need to get bed & temps dialed in.
To help get Manual bed level set especially for Petg on Glass (Ender 3 V2 glass works fantastic with petg if leveled properly AND wait until bed cools below 40 and prints just pop right off), because noone seems to know how to get Petg to print on Glass without using chemicals. Well i print direct on glass in Petg and have never had a fusion in 5years of printing and ONLY manually leveling beds.
To dial in bed level on Glass w/ Petg. As PLA can be far more forgiving of less precise bed leveling.
.4 line width
(The circle slices a bit off in Cura. So may need to tweak the inner wall Line width I had to set mine to .39 to prevent thin walls with gaps within the circular part, causing excessive retraction).
