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!)

• 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

• Quit LinuxCNC
• Disable axis power
• Logout of linux with the “shutdown” option
• Wait for all systems to turn off
• Disconnect CNC
• Stow keyboard, mouse, and extension cord in CNC
• Remove your tool(s) from the chuck.
• Clean up the cutting leftovers. The next user thanks you!

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