Re: ATX power supply unit (PSU) cuts out when all electronics are connected
From reading here in many threads, using an atx power supply has many problems. I use this power supply: [www.trcelectronics.com]

1) imo, the 12v load put on 5v means is no longer 25w, but you could measure the resistance of the light bulb directly and math out how much it would draw at 5v. 2) I dont see different rails on the...

Great Bob!! Temperature control is a process in which change of temperature of a space (and objects collectively there within) is measured or otherwise detected, and the passage of heat energy into or...

I hate to say this, but at some point in circuit density, a multi layer board is indeed the way to go. Stuffing an unbroken ground plane under everything helps a number of issues. It's not going to...

You want a supply that's rated to put out at least 25A. Running a supply right at it's maximum output rating is not a good idea. Low end PC supplies like that one are rated for very brief current...

Do you want to manually change the heated bed temperature as the print progresses? Normally you start at one temperature for the first layer and then switch to another temperature after that It's also...

If you are thinking of building one your self - it's cheaper to simply buy the pre-assemeled version from Rep Rap Discount.

The problem with the decoupling resistors is that they really *need* to be at the source end of the lines. That would put them on the Due board by the ARM. They have already run a long way before they...

FWIW: We've improved the size of the existing ground plane (the back), and provided a number of thick top level paths to alleviate thin bottom/layer connections in various places. I've also added a...

The problem with the edges is a bit strange. The clock rates aren't very fast, but the semiconductor process used for the ARM is indeed quite fast. The result is that the edge rates coming out of the...

We don't need 12 bit resolution on thermistors though. We can also afford to have a lot of filtering on the inputs, because temperature varies relatively slowly.
