HAAS UMC750SS ,UMC1000SS Question

HELLO

I bought the UMC750SS and UMC1000SS a few months ago.

I started having problems with the dimensions.

Dimensions started to differ by more than 0.1.

In Korea A/S, it is said to be the correct setting, but the cause cannot be found.

The period was over a month and a half.

I want you guys to see it and judge if it's right.
