Re: Blown fuse on PC power supply.

I originally thought I had swiped the power switch mounted on my wall when I was trying to determine how far my Y-axis can go before hitting the Socket Cap Screw on the dovetails. I was scratching my head for good twenty minutes. I took a volt meter to the newly installed BOB 12vdc output and wasn't registering anything. The hard E-stop would trip Mach3 and I could see it working with the BOB. However, when reset...Power would not be restored to the machine. I finally opened one of the encapsulated fuses running from the 12VDC line on my PC powere supply into the BOB and found a blown fuse.
312 series, .2 amps (200 milliamps) 250 volt.
I was tempted to just plug in one of the many 12 VDC lines (without the inline fuse on the wires) but I opted to wait and find a replacement.
Has anyone experienced blowing the fuse on the 12 VDC PC supply to the BOB and does everyone use a 200milliamp fuse?
Thanks all.

Jason,
I blew the fuse specifically because I was taking voltage measurements and the multimeter probe tip slipped and shorted the line. Pissed me off because I couldn't find if for the longest time. I put in Slow blow fuses and upped it to 500mA. The rail can handle over 10A, so I don't think increasing it slightly would hurt. Mine's been working great since I did that.

Nate
