Welcome to the SeeMeCNC Community

So I followed the standard calibration for my Max2 by using the paper test at each tower and center. however when I do a test print.(https://www.thingiverse.com/thing:25763) I find that the X-axis and Y-axis (cross and back) are .5mm long and the Z-axis(up) is .5mm short.
It seams I remember hearing something about an advanced calibration instructions, but I cant seem to find them. does anyone have a link to the advanced calibration? .5mm might not seam like much, but its enough to really foul up a complicated multi part model.

Good news/bad news.

Good news: The advanced calibration is posted on the website (https://www.seemecnc.com/pages/delta-calibration-wizard) and it will work on a V2.

Bad news: It's gonna take a while to do this manually since you don't have a probe. You'll have to do the paper test at all 10 points and enter the offset.

I've done it on 1 V2 and that was enough for me :p

Good luck!
