Current Status
Working
Machine is working with minor issues
Usage
This machine requires induction to use.
Due to the ease by which this tool can be damaged much of this course will be hands on. You will need your project and stock metal to use. Alternatively if you have a one-off item Dave Seff or Eris Ryan may be able to do it with you if you ask nicely, saving the need for induction.

Guidelines
Language change: In back of controller move selection key to 1 Menu Rightmost blue option key
Key
Third blue option key from left (middle key)
Memory restore: Menu, diagnostics blue button, >, startup. startup switch, down to power up with saved data, blue button “OK”. Machine restarts. Reference to zero.
Tooling: ALWAYS assume the tool setup with either be wrong or blank if you didn't just set it up yourself. Tool changes need to be done manually.
If machining steels, use coolant (press k6). If you use coolant, please buy more (see below in consumables). If machining aluminum, plastic, brass or other soft materials use air instead of coolant it's less messy.
