The truth about full spectrum

Many of you will of heard about full spectrum laser cutters before, What you probably don't know is that their laser cutters really come from China. I was just doing a repair on a laser cutter from full spectrum and they didn't even bother to relabel the laser cutter. About 30 to 40% of my repair work is currently done on full spectrum machines as they offer limited customer support. In order to save their machines are made in America they will import parts and assemble them here sometimes. The truth is that you're paying four times more for what is essentially exactly the same as any Chinese laser cutter. They also offer about the same quality of customer service as a standard Chinese company.

What type of water to use with a laser cutter.

Never use tap water in your laser cutter it will cause problems for the laser tube.

Based off our research you shouldn't use anything other than distilled water. It looks like plane distilled water is the best thing to use at the moment. We are currently conducting new research into additives to help improve the cleanliness of the water over its lifetime.

An interesting side note. It looks the more conductivity the water carries the worse it is for your machine. 

Maximum and minimum settings

Recently I've been working on maxing out the efficiency of my machine and I've come to some very interesting conclusions.

1. Never cut above 75%. I've even heard arguments to never go above 65% as you did as you're not getting that much extra power but you are wearing out your machine significantly faster.

2. With machines up to 100 W there is no point cutting above 175 mm/s. for the most part you don't want to go that fast anyways because the quality is terrible due to the high-speed. I found on my own machine that anything above that basically produced almost no gains.

3. Most machines won't fire below fourteen 14%.

4. don't engrave above 350 mm/s as the results are very bad.
