how the hell is this thing suppose to work ?

there are no instructions.

This is just what I was looking for but didn't know it. So I just replaced both nozzles and got things lined up and wanted to see how the printer would do Dual Extrusion and it came out fantastically. But what I love is that I now know that .25mm gaps CAN snap out (I think it needs to be thin objects like this) and that 0.5mm gaps are clean and separate. This will be one of my go-to test prints for the foreseeable future. THANKS!

I modified the b object to cut off the LL corner so you can remember orientation

Great Job on the design!

Took me 3 attempts and by the third try the part was spot on. I used my calipers to judge how far off it was each time and after a few tries, got it dialed in.

Thank you and happy printing.

This is a great dual calibration test. I was floundering till i found this and now everything works well.

i see there are small gaps between the squares, and also in the middle. so you expect me to remove all the small pieces from my printbed. those small ones will just stick to it

This is a very easy print to interpret. It only took me 2 iterations to get the nozzle offsets correct. It took 5 with the manufacturers test object.

For those, like me, who were wondering, the top left square should fit perfectly, the top right has a .25mm gap around it, the bottom left is .5mm and the bottom right is 1mm. The circles in the middle are .5mm offset from each other.
