Masherbrum (K1) - Release 2.1

This will be the final release of the Basecamp Edition, this was voted on by the community.

Changes from Release 2.0.1 - Mechanical:

• Move to a hybrid laser cut metal and printed part construction for the z drive system, and the gantry support system. This offers much greater z stability, while allowing the drives to move much more consistently at higher speeds and acceleration rates.
• 60:1 z drive, worm powered
• add support for Nitram's VolcoMosquito hotend
• add official support for Mosquito Magnum+ hotend
• replace squashball feet with a "audio amplifier" type foot

Changes from Release 2.0.1 - Electrical/Software:

• update klipper configurations to reflect mechanical changes and latest release changes (macros, etc)
• remove legacy configurations

Masherbrum (K1) - Release 2.0.1

Changes from Release 2 - Mechanical:

• move ballscrew z and planetary z to deprecated (planetary z may return if encoder support is added to klipper)
• all z drives are now 4 belts only, with 60:1 worm drive

Masherbrum (K1) - Release 2.0

Project Masherbrum (K1 for short) is a Medium Format, Direct Drive, Fully Enclosed FDM Printer.

Changes from Release 2 - RC3 - Mechanical:

• addition of ascender support
• movement of mag+ toolhead to STLs_experimental folder, as it did not meet the launch cutoff period (we still dont have one in hand)
• minor printability improvements on some parts

Changes from Release 2 - RC3 - Electrical/Software:

• update ideamaker profiles

Masherbrum (K1) - Release 2.0 - Release Candidate 3

Changes from Release 2 - RC2 - Mechanical:

• addition of "vertical" variants of controller and power supply mounting brackets (where required).
• controller mounting brackets have moved from using "self tapping" of M3 screws, to brass heat set inserts.
• slice engineering magnum+ support.
• minor strength and printability improvements to the bottom half of the 60:1 worm drive gearbox.
• reduction in mounting screw hole count on all laser cut panels to aid in serviceability (no loss in frame strength).
• use K3 style electrical box corner for uniformity across product line (less material).

Changes from Release 2 - RC2 - Electrical/Software:

• new klipper configurations for all machines, greatly simplified with addition of the "forth coming" annexed probe module
• recommended controller is now either a fysetc s6 v2 or spider with a bigtreetech stepper expander board
• klipper configuration for fysetc dual s6 v2.0 boards (with annexed probe module support).
• klipper configuration for fysetc single s6 v2.0 board with BTT expander (with annexed probe module support).

Notes:

• Ascender toolhead coming soon

Masherbrum (K1) - Release 2.0 - Release Candidate 2

Changes from Release 2 - RC1 - Mechanical:

• add 60:1 worm drive gearbox to z drive, this is the recommended z setup for new builds
• stiffen up toolhead for better performance at 12k+ acceleration rates
• add better cable management to toolhead
• add better umbilical management to toolhead

Changes from Release 2 - RC1 - Electrical/Software:

• update ideamaker profile

Notes:

• Ascender toolhead coming soon
• All future releases will deprecate the usage of the SKR platform, we, as a whole believe there are better and safer controllers out there, and will not be providing any future updates or recommending the usage of these controllers on our platforms in the future
• M3 heatset inserts have been sized to use the Chinese variants across the entire machine (4.8mm holes), as this was a popular request.

Masherbrum (K1) - Release 2.0 - Release Candidate 1
