Frequently Asked Questions

Which is better, the Flux Beamo or K40 CO2?

It depends on your use case. Flux Beamo is 30W co2. K40 CO2 is 35W co2. See the decision guide and side-by-side specs above.

What materials can both the Flux Beamo and K40 CO2 cut or engrave?

Both machines have community-tested settings for 24 shared materials. The settings table above lists every material with side-by-side speed, power, passes, and air assist values for direct comparison.

Is the K40 CO2 (35W) much faster than the Flux Beamo (30W)?

Higher wattage typically means faster cutting and the ability to cut thicker material in fewer passes. The K40 CO2 (35W) cuts thicker material in single passes and engraves at higher speeds than the Flux Beamo (30W). For raster engraving the difference is smaller because surface engraving is limited by mechanical scan speed.
