The buying question this page answers: First diode engraver: AlgoLaser Alpha MK2 or Longer Ray5 — what do the published power options, working area and price get you?
Both machines are diode laser engravers sold in several power versions, and the power you pick changes both the working area and the price. This page lines up what each maker publishes for power, working area and the entry variant, so you can see what the first purchase actually covers before choosing.

When not to buy
AlgoLaser (diode laser engravers: Alpha MK2, DIY KIT, Pixi)
- Less suited to a very small starting budget: the cheapest Alpha MK2 variant, 20W / Machine, is listed at $629.[5]
LONGER (diode laser engravers Ray5 / Ray7 / B1 / Nano, plus UV and 3D printers)
- If you want the machine to come with an enclosure, note that the Longer product page in our sources does not say whether one is included or offered; ask Longer before ordering rather than assuming either way.
Key differences
General
- Power ladders start at different points: the Alpha MK2 offers 20W and 40W, while the Ray5 offers 5W, 10W and 20W, with a 40W column in its spec table.[1][2][4]
- The entry variants are not like-for-like: Longer's $159.99 buys the 5W / Basic Set, while AlgoLaser's $629 buys the 20W / Machine, so the gap in price is also a gap in laser power.[6][5]
- Pick the power level first, then compare the price and working area of that exact version on each page, because both makers change the working area from one module to the next.
Limitations
AlgoLaser (diode laser engravers: Alpha MK2, DIY KIT, Pixi)
LONGER (diode laser engravers Ray5 / Ray7 / B1 / Nano, plus UV and 3D printers)
- The spec table gives a working area per module: 400×400mm for 5W and 10W, 400×365mm for 20W and 385×385mm for 40W. The same page also mentions a base of 400 x 365mm expanding to 850 x 850mm, which refers to the Large Format Expansion Kit rather than the standard machine.[4]
- The power figures do not line up across the page: the purchase options list 5W, 10W and 20W, while the spec table also has a 40W column, so confirm which module you are actually ordering.[2][4]
General
- Whichever machine you buy, read and follow the manufacturer's own safety instructions for it; this page does not add safety advice of its own.
