JNBD - A transparent compressed network block device daemon
 +
 +
JNBD is a NBD daemon implementation in java. But instead of serving an actual block device it transparently compresses blocks into files. Its primary use is to serve a read/write compressed storage device in a platform independent manner (on the server side!) over a network. Any filesystem can be setup on a jnbd instance without the need for the actual filesystem to support RW compression.

CNC Mill - Migration to EMC2

The CNC mill was initially operated using WinPCNC which turned out to be limited, error-prone and confusing.

  • Researched alternatives and decided EMC2 to be the best candidate (open source, feature-rich and stable).
  • Extracted physical parameters from the CNC and configured EMC2.
  • Created a custom Ubuntu live CD for evaluation.

Ctrl-Cut

The Metalab Laser Cutter (Epilog Legend 36Ext) is shipped with a windows-only driver which needs to be operated from Corel Draw. In addition job optimization is insufficently implemented and might even lead to undesired results.

  • Reverse engineered the PCL based job format
  • Implemented cups backend
  • Wrote a postscript printer description
  • Implemented optimization algorithms avoiding problematic cutting order and reducing job duration.

Status: alpha
