Topic: Power shutdown on attempting to print.

I've a problem where the printer will drop power (power switch still on, no LDC, no function) on attempting to print.
I suspect a short dragging down the PSU, however...
I have function in all three axis.
I can heat the printer bed and extruder.
I can also feed the filament.

Got me stumped. Any help appreciated.

Although probably unrelated, I've also found a small white rubber cap in the drip box.

Re: Power shutdown on attempting to print.

Sounds like a bad power supply. It can't sustain the current needed to do all operations at the same time which is what happens when a print starts.

Re: Power shutdown on attempting to print.

Was my first thoughts. However it heats the bed and extruder at the same time. I would have thought the start up voltage would have been greater than the draw from the stepper motors and keeping them heated.

I considered there may be a short somewhere that is dragging down the PSU. But as I can cycle through heating and all axis without tripping the PSU then I'm pretty much out of other options.

Given it's only a 200w PSU I suspect any additional draw is simply tripping it and that by placing a slightly upgraded PSU in the unit it'll negate any trip that I'm currently receiving anyway.

I gather this is a common upgrade?? http://www.solidgearusa.com/en/product_4/22/

Re: Power shutdown on attempting to print.

My guess is that the bed and extruder are taking it right to the edge and once the motors kick in they shut it down. When I had my 1.0 the same thing happened and that supply you show there is pretty much the one I replaced mine with. I think mine was a 350 but the 320 should be more than enough.

Re: Power shutdown on attempting to print.

I would guess the hotend heating element short circuit when hotend moves. try adjust the hotend heating element wire and fix the wire with kapton tape so that is will not shake when hotend moves. order replacement heating element if it is indeed problematic. It should be a quick and easy check before order new power supply.
