Frequently Asked Questions

Which is better, the Longer B1 or Atomstack X20 Pro?

It depends on your use case. Longer B1 is 22W diode. Atomstack X20 Pro is 20W diode with 400×400mm bed. See the decision guide and side-by-side specs above.

What materials can both the Longer B1 and Atomstack X20 Pro cut or engrave?

Both machines have community-tested settings for 23 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 Longer B1 (22W) much faster than the Atomstack X20 Pro (20W)?

Higher wattage typically means faster cutting and the ability to cut thicker material in fewer passes. The Longer B1 (22W) cuts thicker material in single passes and engraves at higher speeds than the Atomstack X20 Pro (20W). For raster engraving the difference is smaller because surface engraving is limited by mechanical scan speed.
