This guide is a work in progress. It does not currently describe the full build process.
This is the official build guide for the LayerFused X301 printer. In addition to this textual guide, we have a series of YouTube videos that walks through building the printer. These videos may not hold up over time so this documentation will be the primary documenation
A number of tools are required during the build. To make it easier to ensure you have all of the tools you need, we've made a comprehensive list below. Each step will also contain a list of tools you'll need for that specific step.
Note: Linked products are for reference and convenience purposes.
Not required when buying LayerFused X301 Complete Kit
The build leverages several plastic parts which can be printed or purchased.
We offer an X301 printed parts kit on the LayerFused store. This kit includes all parts required to get the printer up and running. Some additional parts will need to be printed on your X301 prior to putting the finishing touches on your printer.
If you live outside the USA, it may be cheaper to find a local service or individual to print these parts for you.
If you do not have a printer, you can ask a friend or look for local maker spaces that have printers you can use. We'd recommend buying at least 2kg of filament to ensure you have enough to print the parts including potential failures.
The Frame is the most important part of the 3D printer. This needs to be rigid and square. Take your time and ensure that everything is put together properly and as square as possible.

How do I make it work?
LayerFused maintains a fork of the Marlin Firmware. This fork is tested throughly for bugs and issues before it is updated to the latest version to ensure that everything works well with the printers.
Before you Begin
-Make sure you have VS Code with the Platform IO plugin installed on your machine.
-Clone or Download the Repositiory from the LayerFused BitBucket
Does it work right?
Check all the things
This is usually caused by one of two things. Either the frame is not square or you have one belt longer than the other. Adjust your belt by one or two teeth and this usually alligns the gantry so it is square. Leave extra belt on both sides until you're satisfied before trimming.
Print something AWESOME!
