XY calibration sheet graphic is confusing

Recommended Posts

The text on the XY calibration sheet (both the old V1.5 version packed with my UM3 and the new V1.9 version that's for the S5 as well) does a pretty good job of explaining the operation clearly.

 

But I would say that the graphic showing you how to select a line actually confuses things again. The problem is that the difference in spacing between the Material 1 and Material 2 lines is much greater on the graphic than it is on an actual calibration print. So before I tried calibrating the real printer, when I looked at the graphic that was trying to show me 'See, choose +15 because that's perfectly lined up; don't pick -3 because that's off', my response was "Okay, but why wouldn't I choose -6? That's perfectly lined up too. Am I missing something? Would they both work?"

 

That situation -- two pairs of lines that are both perfect matches -- can't happen on the real calibration print (unless something is terribly off).

 

Is there a reason why the graphic takes this approach? Wouldn't it be better to use line spacing that better matches a real calibration print?

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
