Hm, I might be an idiot but not an "I"diot. Today I could create folders but they did not stay until next time used. I must have done something stupid with the stick and have to check myself what is going on. > What are the permissions on the USB stick. Just do "ls -l" and see. > Likely the

Re: [Emc-users] "I"diot USB stick not writable

What are the permissions on the USB stick. Just do "ls -l" and see. Likely the device now is owned by a group you need to be a member of in order to have write permission.But you can use "sudo chmod ..." to do a one time fix. On Mon, Dec 26, 2016 at 12:03 PM, Nicklas Karlsson

Re: [Emc-users] Noise problem found, but not fixed.

No, SOME switched mode supplies are noisy and need external filters. Many of the are very good. The problem is you never know what you will get if you buy stuff on eBay. Even if it says "Genuine Acme Brand" it may not be. There are MANY fake products sold. What I do is buy and test out one

Re: [Emc-users] Noise problem found, but not fixed.

What's this for again? I have found it preferable to use one of the DC/DC converters off the 24v power supply for steppers (or 48v, but that's a different story, that requires an HV converter and the ones they sell are all- ALL- fakes, you have to mod it with real components). Danny

Gene, Does your Mean Well have "Made in China" wrote on it? My 24V - 20A Taiwan labeled Mean Well's were pulled from industrial equipment, and work quite well. The 12V - 20 A Chinese labeled one, that I bought last year off of Ebay, lost it's magic smoke after a week of intermittent

Re: [Emc-users] Noise problem found, but not fixed.

Switched power electronics are horrible noise sources. Common mode chokes in the form ferrite cores usually dampen the noise. 2016-12-29 7:07 GMT+01:00 TJoseph Powderly : > I'll second the meanwell p/s > but the name is just so ... apologetic :-) > mine have sticker 'finely
