Whoops
I use a laptop to drive mine, so you got off lucky I think… ;p
I guess this is a hint that you got a too large cnc. (Im just jelous).
Just out of curiosity, do you usually use your CNC mill as a spare desk?
@Anton_Fosselius They’re a empty flat surface in a shop… So yes, of course… lol
Ouch. I keep mine on the spoil board too. I worry that this could happen to me if I forget to move it while starting a run if something goes wrong with my code.
Hell I have had a few electronics that need to meet the Mill, just keep having flashbacks to the movie “Office Space”… Lol getting all midevil on the tech. 
Next time clamp your work down better, for best results.
Oh doh, laughing and slapping forehead at the same time. Key clearing doesn’t look too bad but you might try using coolant next time. 
@marmil
you think coolant will cut down on that fuzz they’re getting on their cut? That may be down to a dull cutter, or improper tool geometry too? Sometimes for plastic I like to use high pressure air as a coolant. It is messy, because it shoots chips everywhere, but it keeps the work clean.
I think we all have a clamp-or-2 that has suffered a similar fate!

@Paul_Frederick no, I said to try coolant as a joke, because spraying liquid on electronics would make this an even more fun learning experience. :o
I do appreciate your insight though.
@marmil
liquids only hurt electronics when they’re powered up. Which I have to assume that keyboard was when it got run over. But keyboards are kind of designed to sort of survive some liquid splashing. When I worked at a board assembly house we ran the boards we wave soldered through a dishwasher to get the water soluble flux off of them. The first day the boss told me to load the dishwasher up with boards I thought he was playing with me. But nope, that’s what we did. He swore by Whirlpool brand dishwashers.
Skynet has born…
Man you guys got it all wrong a downward cut or straight flute end mill would totally been the appropriate end mill! Haha. Thanks for posting great add!
and then he realized…he could mill a better keyboard with custom keys.
I wish people would post speeds and feeds when they show off
@Curtis_Cummings
this job looks like it ran variable feed to me. Until the tool could finally get in position to clamp the work down, and really dig into it.
Yes I believe your right. It’s hard to tell with the angle of the workpiece , but I think he ramped in as well. @Paul_Frederick
It was doing 12000 rpm and about 5000mm/min it actually stalled the spindle! It was just a straight g0 move to the entry point. It definitely moved around, when I first saw it happening I thought it might push it out of the way, no such luck.
@Paul_Shaw thanks for that. This actually hit home a little. I’m always forgetting my keyboard on the front of my machine. Thought to myself “one day your gonna cut right through that”.
