Hi
I need some advice about voltage etc.
We have a laser cutter - engraver which we have been running flat out with a big order. We worked over the weekend and the wood we engraved came out quite dark. Now when we engrave it is still engraving but not dark.
Is there any way to know if we put in an automatic voltage stabliser or a constant voltage transformer whether this would help before buying them? Is there someone you guys could recommend to come and measure what the machine uses and what solution would work?

What I know about this is dangerous, thus am looking for an experienced person to help.
