I have a pattern and stock that I’ve been using for a while (3mm birch ply, simple finger joint box) and it always came out with a super tight friction fit. However, over the last week or so things don’t fit tightly and I’m seeing that I need to use glue to get the box together.
I’m not sure what is going on, to be honest. I may have juiced the power a bit (I’m using non-proof grade and had some stock with big glue filled voids). But it may also be a software update in terms of focus that changed the size of the kerf. Or perhaps the machine/laser is ageing and that accounts for it.
Has anyone else experienced inconsistencies like this over time?
