It is NOT the least bit shaky here Matt, I have a larger 5 amp psu, which is also running 360 GB worth of SSD's on usb3 adaptors, and a 7i90HD i/o board + 3 7i42TA's and a small 350 WA UPS on mine, and the only reason it gets rebooted is if a library it needs gets updated.
Uptime is 2 days ATM, but was north of 2 months when I rebooted it to replace a json library on Thursday evening. I can't recall the last time I had an actual crash, its that rare. I don't use that ultra puny wall wart psu supplied, its well known to not be big enough as also is the OTG port it plugs into. I am feeding it directly on the 40 pin header. I also have 4 teeny heat sinks stuck on it, cooled by an ex-video card ball bearing fan. A 12 volt fan running on 5 volts. And its building LinuxCNC from github about 5 to 7 times a week as commits are being made. A full build is getting close to 2 hours as docs are being added. Here, with a decent supply and a small bit of cooling, it Just Works. > Thanks, > Matt > > > _______________________________________________ > Emc-developers mailing list > Emc-developers@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-developers Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
