⬢Y-holder-front and Y-holder-back part (first picture), replaced by new part Y-holder (second picture).

⬢Y-holder is now the same for all four pieces, but the assembly remains the same as with the previous version.

⬢The initial design for wrapping heatbed cables included NYLON filament and spiral wrap.

⬢Starting February 2018 is the spiral wrap and NYLON filament replaced with the textile sleeve.

Each wrapping system has its own chapter 7. You can distinguish between them according to their name or using last step in chapter 6.

Current version of the printed manual includes textile sleeve, for spiral wrap please visit online version at manual.prusa3d.com

⬢Design of both X-end printed parts is updated. New tensioner enables easier belt post-tensioning. Chapter 3 includes one extra step. Chapter 4 includes more changes.

⬢Design of the X-carriage printed part is updated. Belt holding mechanism is completely redesigned. Chapter 4 includes new steps including belt trimming.

The printed version of the manual includes instructions only for the newest design, for old design please use the online version.

⬢Assembly of the Extruder updated according to the user's feedback and internal testing. The nylon filament is inserted earlier and surrounding steps were adjusted accordingly.

⬢New spool holder is introduced. This version requires assembly. See the last steps of Chapter 8.

⬢Small improvements across all chapters.

⬢Assembly of the heatbed with the textile sleeve updated. In case the wires, aren't soldered user has to tighten the cable to the heatbed using M3 screws and nuts.

⬢Recommended torque for M5x16r screws added, see Y-axis chapter.

⬢In order to improve cooling efficiency, there are new extruder parts version B7/R3. The assembly process is mostly the same as before. For steps which differ or are completely new, the user is informed and all details are explained.

⬢Extruder body (compared with previous B6)

⬢Extruder cover (compared with previous B6)

⬢More information including direct comparison can be found on our Prusa Research forum.

⬢There is an update to the cable management for the extruder. Previously used spiral wrap is replaced with a textile sleeve. Also there is an update to the position of the zip ties.

⬢The case for the Einsy board was updated to provide easier assembly of the cable bundles and also to enable easier access to the optional Raspberry Pi Zero W.
