DIY

Welcome to the LM42P self builder page

You can purchase either the m1 or m2 variant of the LM42P. These machines are available as DIY kits or fully assembled, depending on your preference. Based on your budget and level of maker experience, you can choose the components you need.

Each machine comes with a complete Building Guide (PDF), which includes everything required to build it yourself: a full parts list, specialized jigs (called drillator), 3D-printable files, firmware code, schematics, and more.

The power unit is the same for all LM42P machines. There are two power unit variants available: one with lower power using a TB6600 driver, and one with higher performance, called power unit p, which uses a Gecko driver.

Because this machine is only produced in small batches, its price is higher than most F-machines on the market. Without large-scale production, selling it at its true cost is simply not possible. I know it’s a high-quality machine, and I think it’s a shame that so few people get to use it.

More and more people have asked me for the plans to build it themselves — so I decided to make this project open source.

Writing this page took me a lot of time and effort. If you’d like to support the project, you can make a small donation by clicking the PayPal logo below, or help out by subscribing to my YouTube channel.
