Thick Parts

[Galad 0]

I've recently upgraded the 2 to a 2+. Machine is working fine so I'm looking at accuracy over a variety of conditions (nozzle/speed). One thing I'm seeing consistently so far is the parts coming out thicker then designed (Z-Axis):

* Designed .125" thick comes in at .136" ± .001

* Designed .025" thick comes in at .033" ± .002

* Designed .050" thick comes in at .057" ± .001

* Designed .100" thick comes in at .110" ± .001

I'm running PLA. Version 15.04.6ex

Is this the expected variation in the machine?

Since it's so consistent but on the high side, I'm wondering if there is a tweak which may get the average closer to the target...

Thanks..

Tweak your bed levelling a bit? Still, I would say two tenths of a mm is pretty decent...

So it wasn't so much the bed leveling. However it was build plate calibration. Even when you follow the instructions, there is a difference between a loose/subtle fit between the nozzle (with the card) and a snug/tight fit. Once I adjusted it to a tight fit, my target values were pretty much right on the designed values.
