I like "dilate/expand" instead of offset or shrink, but agree strongly with this statement. The current labelling and tooltip for this feature is hard to figure out what it means. It's a hard process to describe: it doesn't act on overall geometry but rather alters the volume of the object by dilating/expanding the shell in the X/Y plane.bapro wrote:When pointing your mouse at this feature it says (shrink)???? Please change this to offset if that's what happens. Shrinks gives more of a feeling of scaling that is something completely different.
That's exactly correct - but the extrusion multiplier is responsible for the top of flat prints being concave or convex which can alter the height. I don't usually find that the problem is the extrusion multiplier, myself - though if it's off within a low multiple of the layer height (eg., you're printing .1mm layers and it's off by a little over .2mm), it's a possible culprit. I'd check for extrusion multiplier problems against a straightedge rather than a micrometer though. The most obvious symptom of the extrusion multiplier being off is that flat horizontal surfaces won't be planar.Wolfie wrote:Wait, what? I was under the impression that "Extrusion Multiplier" affected how much material was extruded, not the actual z steps. Was I wrong?
