ftxprusa is a build log and configuration set for a homemade 3D printer, not a piece of software you install. The project combines two real printers: a discontinued Folger Tech FT-6 and a Prusa MK3S+ that had spare parts left over from an upgrade to a newer model. The creator kept the FT-6's frame, linear rails, heatbed, and power supply, then swapped in the Prusa's extruder, mainboard controller, stepper motors, and screen display. A Raspberry Pi Zero 2 W running MainsailOS controls the whole machine, and Klipper is the firmware that drives it. The README documents an eleven step build process covering stripping the FT-6's original electronics, transplanting stepper motors between the two printers, drilling new holes for wiring, and wiring everything into a shared control box. It also walks through calibration steps such as leveling the bed, tuning heater PID values, checking idler screw tension, and calculating extruder steps per millimeter and pressure advance. The repository includes the actual config files and test gcode the builder used to get their printer running. This is a personal project for people who already own 3D printing hardware and want to repurpose old or spare parts rather than a general tool anyone can pick up and run. The author is upfront that the instructions are rough and unpolished, and that the finished machine still has quirks: an inconsistent z-axis, tilt caused by the two z-axis leadscrews not being synced, and some unresolved power issues. Even so, they report it prints reliably after about five days of tuning. Use cases here are narrow: anyone restoring a Folger Tech FT-6 with Prusa parts, or looking for real-world Klipper and pressure advance calibration values, would get the most value from this repository. It is a documentation and config repo rather than an application.
