2 days ago I received my Nomad 3 and due to some Misunderstanding of how bitzero works - stalled my spindle in some 6061 aluminum with a 1/8 flat end mill.
Now the spindle won’t start again despite moving freely by hand and inputting m3 s10000 into MDI.
I have a ticket in and I have read a few posts here about spindle boards being damaged when spindles are stalled for various reasons. I figured I would post about it for anyone trying to do research on these machines before they buy.
In my case - I wanted to work both sides of some 6.5mm aluminum stock. I milled a nice square corner of the stock and used bit zero to machine the first side. Then I flipped the stock over and used bit zero again, but this is when I discovered there is no way to “inform” the machine that bit zero is now in the UPPER left corner instead of the lower left corner. I thought that information would translate over from carbide create - where you setup your stock - but it doesn’t.
So I zeroed the x, y and z axis individually l. However - I failed to verify that the z-zero was accurate and it wasn’t. It was off by 2.2 mm or so and the end mill aggressively plunged into the aluminum and stalled the spindle.
Well now I know… index the spindle manually until I can take the time to learn the quirks of bit zero and always verify that any automated thing is doing what you expect it to do before hitting go. Or don’t be lazy and square off all sides of the stock then use bit zero within the confines of its design parameters (in the lower left corner of the stock) and create my tool paths accordingly…
