), let the bed reach temp for about another 20, warmed the E3D, and ran a test print without lights flickering or temp fluctuations. Question - what firmware are you using, and did you redo the BED PID stuff with M303 E-1 S95 C8 etc ?
Perhaps the problem is as simple as, BED PID is enabled, but the PID values are way too small...
I'm guessing that question is for me? I don't know exactly what I had on there but it originally came from you. It worked for him for a while though so I'm guessing power issue. And yes I changed the PID values to the SD values.
]]>Same, and it's made worse by the motors moving. All related to how much power is being drawn at any given time.
Indeed. We are having the same issue.
I think the limitation is in the printrboard somewhere, maybe the main power connector. All conjecture, I'm investigating further at the moment, but could be interesting.
Power supply you linked looks like a goer (specs are right).
I am currently running on a Sang graciously loaned to me. So I don't think the board is the issue. All fans, except my extruder nema fan, are running off a separate ps with a splitter, so I know it is not drawing too much from mods.
I would enjoy reading the conclusion to your investigations
The lights only flicker when I start heating, so I am pretty convinced the supply is beginning to fail to some degree.

However, I've got mine hooked straight up to a 30A lab supply (via the original cable/connector) right now and it's still doing it.

]]>Edit: Don't forget to check the 110v/220v on the new psu. Mine was set for 220v and the printr board was not happy with it.

Showoff 
Did your stock PSU totally fail?
Nope. But I am once again limited to PLA since the bed will not stay at the desired temp, so it is eternally sitting with a warmed e3d in limbo. E3D may be all metal, but I know it can't be good just sitting constantly waiting at temp for the bed.
The lights only flicker when I start heating, so I am pretty convinced the supply is beginning to fail to some degree. Plus, it takes a LLLOOOONNNGGG time to heat the bed. Much longer than before.
This one should do the job, correct?

Yep, Don't throw your old one out. (I know how to solder ) Did your stock PSU totally fail?
but my lights are flickering.
Gah! I have this too, it annoys the bejeezus out of me.
I think the problem is probably at the board level, you'd have to rewire the lights direct from the power supply to avoid it I think.
Here's one I think is a good safe pick, but you decide how you feel about $80: http://www.mouser.com/ProductDetail/Mea … 5tNmzfk%3d
Or if you're brave type "350w 12v power supply" into eBay. I've taken a punt on these things before and have been pleasantly surprised. The prices look around the $30-50 mark. Note that 350W is way more than you need, which means if these things are cheaply made and are actually only good for 200W you're still well in!
Also, I am unsure how long this has been going on for, but my lights are flickering. So I think it could be how much power the E3D is demanding. Which brings me to my next question....
Anyone know of a good power supply at a decent price? Links massively appreciated!
