XY calibration custom pattern

[assaero 1]

Hey all,

I recently joined the UM world by acquiring a used S5 (old hardware revision, updated to 8.3.1). I am very satisfied, but now started to experiment by acquiring a AA.8 and AA.25 core in combination. This creates trouble in the XY calibration, as I use the titanx from formfutura and it does not stick to the print bed when trying to use the XY calib pattern print. I did a full Z-calib and tried again with same results. Printing itself works fine with a z-offset of -.10 to -.15 (albeit with material overlap due to XY uncalibrated). I read in an older post that the pattern height is hardcoded. Can I offset it anyway somehow or is it perhaps available as a cura project file so that I can print it with a lower z-offset?

Merry Christmas!

I know quite a few people who just don't bother with xy calibration and it works reasonably well.  There's a way to just enter the values without going through the procedure I believe?  So you could I suppose do your own xy calibration pattern and calculate how much to move.  The other trouble is I don't know the units for the values in the xy calibration.  Each unit might be .1 or .05mm?  I don't know.  Someone knows as someone posted this information once long ago.

A value of 1 equals 74 micrometers

I created now my own pattern for the same purposes. Not as nice as the official one, but can be printed still with two different nozzles and you see the deviations. Center box should be exactly aligned, and then its towards the left negative deviation to be entered, to the right positive, combining x and y:

 

-3   -1   0   2   4

-4   -2        1   3

 

This is for anyone wanting to use it, enjoy.
