Since a few day I am the (happy) owner of an UM3.
And I am happy, because all I printed till now came out as ordered. (all errors were mine, not the printer)
Except one thing: accuracy!
Before deciding to buy an ultimaker I had a test print made on an UM2 and was suprised of the accuracy.
In the design is a slit for a credit card that should be 54mm and it measured 53.97mm - very good considered the print was done in the lowest possible quality (for time reasons)
Printing the same STL file on the UM3 in normal quality measured 53.81mm!
Almost 0.2mm smaller. (and the card does not fit anymore)
As far as I can see there is no way to calibrate this. Or is there?
Where do I look? The machines were different, but also the slicer versions of cause. (cura version 2.1.3 versus 2.3.0)
