Snappy v3.0.3

Adds some firmware tweaks and makes the adjustment screw a bit more durable.

Snappy v3.0.2

• Adjusted Z tower base height to make Z-min limit switch adjustment viable.

Snappy 3.0.1

• Adds adjustable Z-min endstop mounts.
• Changed Z homing to Z-min.
• Other minor tweaks.

Snappy 3.0

This release changes the Z axis drive considerably. Some things of note:

• The Z axis now uses lifter screw rods with stabilizing rails.
• The weight of Z axis bridge is massively reduced by moving lifting motors to tower bottoms.
• Z axis wobble is significantly reduced due to the rails.
• The vertical size of the build volume increases to about 220mm.

Snappy v2.0.2

This release fixes a number of issues with the original 2.0 releases. The Z axis is still too wobbly, but I'll fix that in 3.0.

Snappy 2.0.1

Fixed issue with blocked joiners in jhead platform.

Snappy 2.0

Improves upon the Snappy v1.1 design in the following ways:

• Replaces metal lifter screw rods with printed worm gears and racks.
• Replaces binder clips with adjustable bed-leveling mounts. Yes, you can now adjust bed leveling!
• Towers and bridge assembly use less plastic.
• Improves reliability of X and Y homing switches.
• Increases build volume to approximately 195mm x 195mm x 165mm.
• Extruder idler should now provide more pressure on the filament, for less skipping.
• Cable chains should be stiffer and stay together better.
• The extruder bridge is now arched, to reduce sag issues.

Snappy 1.1j

Added wiring routing documentation and cable-chains.
