1 Notes

3 axis machines are nice for very simple prototype parts but as soon as you need to mill objects from multiple sides with multiple tools this can quickly become a a pretty manual process. A 4/5 axis machine could solve that problem though these are drastically more expensive. If this machine could not only be used for prototyping but also for production at a certain extend it could quickly pay for itself though.

Things to look out for:

  • control software future-proof (Linux, open source)?
  • replacement parts are affordable and quickly available?
  • tool selection (requires expensive special brand/kind)?
