Hello all,

I work for a small company that has recently (within the last year) acquired a Laserpro Mercury 40w CO2 laser engraver secondhand.

After a few small hurdles we were able to get it running like a champ. But lately it's been having problems with raster engraving.

It has no problem at all with vector cutting. But when it tries to raster, the power is lacking and it sometimes appears as though it doesn't fully fire. When I engrave a softer material, there will be a slight raised section at one end of the cut. As though the power is ramping up as it moves instead of just firing.

I can try and get pictures of this if needed.

I've tried cleaning the available optics (mirrors, lenses, etc) but it hasn't helped.

The thing we're wondering is that maybe it needs recharged. But why would it be able to vector without problems but not raster?

We're still rather new at this so any help would be greatly appreciated.
Thanks.
