Cupcake Skeinforge Usage

Using Skeinforge With A Makerbot Cupcake

This page is for capturing the subtle nuances of slicing and rafting fabjects for printing on a Makerbot Cupcake.

Wherever possible, all settings should be explained, related, compared and contrasted using a printable fabject like the Printing Testpart for RepRap Machines.

For information on how to tune Skeinforge for your particular Makerbot, check out this page: Configuring Skeinforge.

Default Skeinforge Settings From Scratch

• Put a usable set of default skeinforge settings here as set from the UI to future-proof against changes in .skeinforge directory structure, file format, etc.
• Current values pulled from Skeinforge UI shipped with ReplicatorG 0005 with skeinforge_makerbot.zip unpacked in ~/.skeinforge.

MakerBot Skeinforge Settings ZIP file

• You can download the skeinforge_makerbot_visible.zip file instead of manually entering the settings from this page. The zip file will expand to a directory that is visible in the Finder, hence the filename skeinforge_makerbot_visible.zip. It is identical in all other respects to the original skeinforge_makerbot.zip. These settings are for skeinforge-0005.

Optimizing For Speed

• Get a fabject printed fast - not worried about water-tightness or finish.

Optimizing for Accuracy

• Print Fabject with fine detail, water-tight and 'more accurate' tolerances.

Power User Tips and Tricks

• Overhangs greater than 45 degrees
• Creating flat bridges and arches
• Production Optimization
• Merging skeinforged files - printing multiple fabjects with significantly different settings in one go.

Troubleshooting

• Put troubleshooting tips here, e.g. rafts not sticking, changed behavior between versions of skeinforge, etc.
