Safety at a Glance
CNC machines don't care what they're cutting, whether it is steel, or human flesh for that matter...
Required:
- Safety Glasses
- Clamping devices (apply https://talk.vanhack.ca/t/vhs-group-project-sherline-cnc-mill/2588 liberally; better to have more clamps at moderate pressure than few at great pressure, to avoid damaging the T-slot)
- an experienced machine operator (if this is not you, you must get someone to help you!)
- long hair must be tied back
Optional (but recommended):
- Face Shield
Not recommended (must have a reason why):
- Hearing Protection (The CNC machine isn't very loud, and you will be able to determine how well a particular job is running based on how the machine sounds)
Prohibited:
- Gloves, loose clothing (NEVER near rotating machinery!)
- Unclamped Material (can be thrown off the machine!)
Safe Operation
Startup
- With the power disconnected, clear all non essential material from the CNC working area.
- Connect power.
- Open the front door of the CNC cabinet to access the keyboard, mouse, axis power and PC power.
- Make sure axis power is set to off.
- Turn on the PC.
- login:
vhs - password:
vhs - Start LinxCNC
- Make sure the big red Emergency stop button is off (pulled out).
- Enable the axis power.

- handle any warning messages that LinuxCNC reports.
- Proceed with prep and cut.
TODO: FINISH THIS
Shut down
- Quit LinuxCNC

- We have collets for 3mm, 4mm, 6mm and 1/8”, 3/16”, 1/4“ shank end mills.
- The upper e-stop button should work, but verify that it stops the mill before you begin any real operation.
