Safety at a Glance

<HTML> <p style=“border:2px dashed red;”> CNC machines don't care what they're cutting, whether it is steel, or human flesh for that matter… </p> </HTML>

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.
verify that there are no loose wires and the machine appears to be in good working order
handle any warning messages that LinuxCNC reports.
Proceed with prep and cut.

TODO: FINISH THIS

Shut down

Quit LinuxCNC
Disable axis power
Logout of linux with the “shutdown” option
Wait for all systems to turn off

We have collets for 3mm, 4mm, 6mm and 1/8”, 3/16”, 1/4“ shank end mills.
We have a step block hold down set, a milling vice and a set of extra T-nuts to clamp your work.
The upper e-stop button should work, but verify that it stops the mill before you begin any real operation.
