Software

Tested

Easel

  • HTML5 Web based, XCarve default
  • Good test, OK for home use, limited final use due to log in and web based.

Makercam + Universal G-Code Sender.

  • (Flash+web based. http://www.makercam.com/ )
  • Limited in use due to no path/tool saving, reliance on internet, problems with flash.

Autodesk Inventor

  • GCode exporting tool. Works well. Complicated and expensive.
Current

Vetric V-Carve Pro + Candle

  • Easy to use, works very well, allows work off site. (Makerspace ID: 86B4F-F467A-280D9-9F4C6-9C56B-4C528-BEE6F )
  • Candle(Previously grblController) is friendly and easy to use. Allows custom buttons.

Log of works

  • Original kit dismantling.. (Prior to Holley's arival)
  • First full build. (Started a few weeks into when Holly arrived)
  • Original table. Early dust extraction.
  • Final Vacuum cleaner based Cyclonic Dust extraction system.
  • New custom built table
  • New software(VCarve!)
  • Z-Touch probe
  • New computer, clean install, ready for Public. (Nearly done)
  • Room sound proofing.

Things **TO DO**

  • Room sound proofing. (Critical)
  • Document running procedure. (Critical)
  • Emergency stop needs to connect to an end stop to trigger Alarm.
  • Wiring diagrams need to be drawn up.
  • Dust mitigation. Guards for side wheels and edges. (Acrylic?)
  • New dust shoe.
  • Tooling lists need to be finished.
  • New dust extractor barrel/top/baffle.
  • XCarve Table lowered by 100mm
  • Signage.

Upgrades
