A fast-to-print, low filament use test model to see an overview of IDEX head alignment across the bed.
The model consists of two 0.2mm layers. There is a bottom matrix to be printed with one material, and the top with another. Bottom lines are 1.8mm wide. The second matrix is drawn on top of the first one with different material, with a line width of 0.5. In addition, there are short guide lines that are 1mm apart, and drawn with a 0.3mm to make it as easy to read as possible:

The two black lines in the picture are supposed to be collinear, and in middle of the two guide lines. And since they are not, the print reveals some head misalignment (lines not in the middle of the two guides) and some general non-repeatability (black lines are not collinear).
To use this model you probably need to have the first layer tuned pretty well: variations of the z height might cause a variation in the line widths. Thus you generally should try to look at the line centers, and not just look at the edges.
Print with 0.2mm layer height, and select the
The model is in no way a perfect one, but does give a quick overview of how the alignment varies across the bed.
