I use two kinds of printers, MakerBot Replicator 2x and FlashForge Creator Pro.
At first I thought that when I change my Settings between both two my models changed.
but even now when I import the models after I change the settings to each printer, it's still happening...
BIG problem!
please help?

Go to tools --> firmware configuration, and click on the X3G tab. Make sure that you have the correct GPX profile selected. The FF Creator Pro uses the Rep1 dual profile while the Rep2X obviously uses the Rep2X option.

Those two profiles have different steps per mm values, so if you were printing on the FF Creator Pro using the Rep2X GPX profile, your parts would definitely be undersized.

Tnx, checking it now.
