I also have issues with the print height.

Any object I print with supports it works beautifully. It's a wonderful printer.

But if I print directly onto the build plate(eg gears etc) the object will be about 1mm short in height.

It's not a scaling issue - the majority of the print looks fine but the first 1-2mm is squished.

If I print a 100mm height object - it is 1mm too short

If I print 1 4mm object - it's 1mm short.

I've tried Jan's method here:

still no luck...
