Is there a power supply requirement difference between the BBB and a BBBW?
The BBB works great outside of my machine connected to USB on a computer, but within the machine it hangs and crashes. The cape powers the BBB, it has a 24v 2.7a supply. I have noticed some funny things (I have to plug it in to the wall first, then the device; it won't start if the device is plugged in first) with the supply and am in the process of trying to acquire a new one. /J On Monday, December 19, 2016 at 7:09:19 PM UTC-5, William Hermans wrote: > > If your power supply reliably supplies 1A or more, at 5v, then that's > probably not the problem. > > On Mon, Dec 19, 2016 at 5:00 PM, Jay Doobie <[email protected] > <javascript:>> wrote: > >> I think I know what is going on, I think the BBBW uses a bit more power >> than the BBB, I believe the power supply that came with my 3d printer may >> either be faulty or at it's limit of what it can supply.
