silhouette cameo cut accuracy help!

You are so welcome. Some of gals around here that own the machine did not use the function you are speaking of so we really stuck on how to help you. I'm so glad you got it figured out and its working for you now. Have a great day!

Thank you so much! I've been doing some research. I couldn't really find anything helpful, but I did end up doing a reset to restore factory defaults, and that seemed to fix the issue. I'm not really sure what got changed to cause the problems I was having, but it seems to be alright now.
Thank you for checking around for me!

I'm checking around to see if there is someone here who can answer your question.

Hello all! I've been having a new issue with the registration marks feature on the silhouette cameo. I print out pictures and cut some precisely measured shapes using the registration marks feature.
Recently however, my cuts have been coming out slightly too big. (Like 1mm or less)
I've tried to troubleshoot this and am having no luck. Here is what I have done so far....
When I simply create a specific size shape in Silhouette Studio and cut it out, it comes out perfectly.
When I add a picture and registration marks or even just reg marks and no picture, my shape cuts out about 1mm too large.
A couple other things I've tried....
Cutting out the shape with reg marks on a 4x6 paper, about 1mm too big.
Cutting out the same shape on an 8.5 x 11 paper is more accurate, but still about 1/2 mm too big.
I have not had this issue in the past. Anyone have and thoughts on what to try?
Thanks so much!!
