Calibration issues

#1
Hi,

Im able to print items just fine, nice quality or so i though. Everything i printed until now i havent needed to worry about scale i was getting ready to print out the files to add a large printer to the toolbase however when i print the components the models seem to come out oversized on the x/y scale.

Can anyone help offer advice on dialling in the settings. Ive read a few articles on skienforge that are ment to address this but have had no luck. Is there away to correct this issue in slic3r.

Many thanks

Nw
