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

X-Carve User Guide and Operations

Basics

~~REVEAL~~

Safety

Basics

Don't put hands in machine.
It hurts to have fingers cut off.
Wear clothes.
It'd distracting to other users and against policy.
No loose clothing or long hair
That really was a nice tshirt or scalp…
Don't cut anything you don't own.
Think about how you would feel if it was your thing.

Required PPE

Hearing protection
It's a better story to loose it at a rock concert than operating this machine
Eye protection
The replacement ones are awful. It's not worth it.
Covered Shoes
Something you should be wearing anyway.

Optional

Respirator
Looks scary and protects your lungs.
All over body condom
You can never be too safe.

Material Recommendations

Best

Soft plastics
- HDPE
- LDPE
foams.
- Dence Polystyrene
- Light weight polystyrene
- Expanded PVC
Cork.

Noisy

Hard plastics
- Acrylic
Wood
- Plywood
- Pine

Avoid

Solid PVC (Tends to clog bits)
Leather (Fibrous. Cuts but clogs bits. Stinks.)

Tooling and cutting speeds

Operations

Machine start and verify basic operation

Ensure work space is clear of tools, etc.
To activate the machine, 'STOP' button needs to be lit up green, if this is not the case, turn red knob clockwise(direction arrows) until it pops up.
Open or switch to Candle(Machine control software).
Verify 'Machine Status' does NOT say 'Not Connected' ('Alarm' or 'Idle' is OK), if not contact Supervisor.
Good: Bad:
Press 'Reset' above the Emergency Stop button.
Press 'Home' Machine will move to find end stops.
Status should flash green 'Home' then display 'Idle', if not or if the machine makes grinding noises, doesn't home or has other problems contact Supervisor.
Good: Bad:

Installing and change of tooling

Loading and running a job

Post-use shutdown
