The Model Mill is suitable for cutting materials softer than or equal to:

If you hear loud bangs or screeching noises while milling, you should:

Ignore them - all machines make noises
Wait a while, see if they go away
Run screaming from the room
Press the big red stop button
When inserting a milling bit into a collet, you should:
*
Force it in, using a hammer if necessary
Guess the shank diameter of the milling bit and find a collet roughly the same size
Measure the shank diameter of the milling bit, and match it to the same diameter collet
Don't use a collet at all
When moving the spindle head/milling bit under manual control with the front cover raised to align the milling bit with the workpiece, you should:
*
Take no precautions - nothing bad can happen
Make sure no part of your body is inside the milling machine workspace
Hold the workpiece down with your hand
Hold the milling bit with your hand
If you want to view your work then resume cutting, you would:
*
Press the big red stop button
Press the start button
Press the View button
Just open the front cover - that'll stop it
You have started your milling job. Now you should:
*
Just wander off and come back in a few days when it has finished
Go sit on the other side of the room and work on a pc/another machine
Stay beside the Model Mill ready to switch it off if there are any problems
Nip off to the bathroom - it'll be OK running unattended for a few minutes
The mantra "Lefty loosy, righty tighty" is:
*
A cynical view of modern politics
A reminder of how screws work
An annoying verbal tick by the trainers/owners that can safely be ignored
A reminder of which hand should hold the larger spanner when inserting or removing a milling bit into the spindle head, designed to prevent damaging expensive collets
After setting the Z-height with the sensor, you should:
*
Be sure to remove the sensor before you start cutting
Do nothing - the milling bit will knock it off on the first pass
Unplug the sensor and remove it from the machine
What's a Z-height sensor?
When removing a milling bit from the spindle head at the end of a job, you should be careful of:
*
The sharp edges of the milling bit
The possibility that the milling bit will be hot from friction
Dropping the milling bit as you unscrew the collet
All of the above
Cleaning the Milling Machine at the end of a job is;
*
Not my problem
Something to which you should dedicate at least 5 minutes to ensure the machine stays in good condition
Just a quick brush around to show willing
It doesn't need to be cleaned after each job
