A year ago, L-Cheapo was developed to provide an open-hardware solution to laser cutting. The L-Cheapo Mark 1 hit 300% of its crowdfunding goal and was delivered faster than most crowdfunded projects in the same category.

Earlier this year, we have made new models of L-Cheapo.
The actual board revision is 2.4 (Mark 2 and Mark 3 use the same board: Mark 3 has more resistors, a bigger diode, and a bigger transistor, but the same PCB, and a refined design allowing to turn most of 3D printers into a hybrid tool that can not only engrave but also cut wood, plastic and leather.
Today we introduce Mark 3. It fits in the same footprint as Mark 2, looks suspiciously like Mark 2, and is wired in the exactly the same way as Mark 2…
This is not about the same product in a smaller case for a higher price. Mark 3 outputs 70% more photons than its predecessor, resulting in fewer passes and deeper cuts. At 3.5 watts optical continuous output, it’s the strongest solid-state cutting laser kit currently available.
Both Mark 2 and Mark 3 are now available with an optional PWM connector that lets you control the output via any logic-level pin, from 15% to 100% (if for some reason, such as engraving grayscale images, you need less laser power).
L-Cheapo Mark 2 MSRP = $195
L-Cheapo Mark 3 MSRP = $295
