A simple question:
How can i set board dimension to a specified size?
For example, if i want my pcb to be 5x4 cm how can i tell eagle to auto size the board (layer dimension) to this size?
Thanks and sorry for my bad english, for me it's very hard even to explain simple questions...

You have to orientate yourself on the coordinates. Based on your point of origin (the little cross or "plus") and the selected grid you possibly have to calculate a bit...sadrew wrote:A simple question:

Hi all,
Just got Eagle to start making some layouts, and trying to make a pcb layout for the GGG boutique late 60's fuzz face, but just have a question...
I first create the schematic by copying the one from GGG, but I can't figure out how to do the off-board stuff? I can manage to put the pots in like the GGG schematic, but the input, output, switch, power etc etc is confusing me? Do I even need them in there and just add pads for connections? how would I do this?
I've had a mosey through gaussmarkov.net and am using the library from there too, and will look through all the other stuff I can find tomorrow, but just thought I'd ask...
Thanks!
Kier.

you don't need to place the offboard stuff, because it's so standard. Just input to output is good enough. You can place pads on the PCB.kierc wrote:Hi all,

Thanks for that, looking OK to me so far
Got another question though... one of the resistors' pins wasn't connected to anything when I went to the board, and the board won't let me just draw the connection.. I'm pretty sure I've updated the schematic to make sure it's connected, but how do I update the board for the changes in the schematic?? or better yet, how do I just draw the connection?
Thanks again

the problem is usually in the schematic. You need to zoom in close and move the connection around to make sure it's connected. Sometimes if the grid measurement is not right, it won't connect. You can't connect in PCB mode, if i recall correctly.kierc wrote:Thanks for that, looking OK to me so far

i have been adding send and return pads from the supply section from gauss' library. it helps when separating the pins with pots. you can have a send, a return, and a ground.chicago_mike wrote:I have switches, Pots, Jacks, etc..that Are in my schematic right now...
BUT : I dont want them on the circuit board. So...before I do the pcb lay out, do I get rid of the parts and just add pads?
Also, how do you make a 9volt supply so you can test the pedal before going to the pcb? I add 9 volt supplies, but I still get a no power error. Im very new to eagle cad so please excuse my ignance'.
And lastly..Auto route..the first layout is pretty hefty..I'd like to maybe place them generically on the pcb, will eagle cad only route where I drop or will it also MOVE the component? I think Protel used to actually move the component around...
Thanks peeps.

I fixed the connection issues I had.. I zoomed in and moved the component with the move tool and it turned out it wasn't actually connected
Thanks again for your help (will post up my layout to ask for someone to check it over now haha )

If you would have used the DRC, Eagle would have told you that the resistor isn't connected. Definitely recommended before starting to layout.

Hm, actually I meant to say ERC (= electrical rule check). DRC is the equivalent for the layout editor.

I founded gaussmarkov libraries are PERFECT for making stompboxes.
But i need to make a pcb for a tube pedal with board-mounted 12AX7s.
Does anyone have libraries for octal and noval tubes?

There is already a library included in Eagle. And, coincidentally, it's called "tubes".
But if not, get this one.
In the download area of the site is a section with lots of additional libraries...

i founded tubes libraries.
i need also lbr for mallory 150 axial capacitors and axial electrolytic capacitors.
did a search on the cadsoft archive with no result
please help

If you look in "rcl" library there are components for axial electrolytic and also for 15mm and 20mm spacing film capacitors that work for Mallory 150 types.

Hi
I've been trying to find this for hours. How do you change the default autorouter track width in Eagle layout editor?
Thanks.

1st: With "Edit/Net Classes..." first define the width of the net classes in plan to use (e.g. default, power_supply, signal).
2nd: In the schematics specify which connections belong to a certain class. In other words, you need to tell Eagle which connection is part of the power supply, which one is the ground...
To do that you can use the icon on the upper left corner. Clink on a connection (aka net), a windows pops-up. Change the "Net Class" to the name defined previously.
Remember to do the above with the schematics and PCB files opened at the same time otherwise the two will go off-sync.
