Thanks for the reply. I already knew all that from my research before coming here.

The issue is several choices in different values, that I do not know, such as fast blow/slow blow..etc. Not sure if this is even the right type. it's from a post dealing with the XL's Modular Bed Board. Hence, having the specs clears this up!

I did not pay close attention when I assembled my Core One, and am away from the printer right now. Aren't those SMD fuses the self-resetting polymer type? I.e. if they trigger, you just switch off the printer, let things cool down, and you can try again without having to replace the fuses?

Edit: Ah, no -- found a photo now. These are indeed conventional fuses which will "blow". But I would expect their electrical ratings to be the same as the automotive fuses which were used before. This assumes that the change was just for better manufacturability (fuse holders can be placed via the pick & place machine) and no electrical changes were made.

My xBuddy Board has the new style SMD fuses instead of the old school auto type. Does anybody know the specs and have a link with more info? I've found similar types, just not sure of the exact one needed. I know it's just a low amp fuse, but their are choices to be made and I'm not an EE (just a dumb redneck)
