hobbycnc/capacitor?

[sixpence]

I may have put my question badly but the info has been invaluable since my electronics knowledge is not as healthy as my as my respect for capacitors. That is why I am asking the questions to make absolutely certain that I don't make a mistake.(Well, trying not to make a mistake). Do I wire the power supply to the circuit board here?

I am sure my dunce status in the electronics dept. is abundantly obvious since the word power on the board should make it clear.
I just don't want to mess it up and I am rather fond of my fingers.
Here are the wiring diags I have.

here it is hopefully. Having trouble ataching it

There are distinct advantages to this.
I have free reign to all household appliances. i.e. 1.the iron for etching the circuit board form Geoff Williams, Hobby cnc book
2. All glass bowls are freely available to use as acid baths.
3. No heavy lifting.I add those to the honey do list
4. I receive an abundant supply of help from hardware stores without damage to the ego because I am not genetically supposed to know what I am talking about.
5. I can get away with using terms such as doodad and thingymajig without anyone batting an eyelid.
6.Discounts seem to be in direct proportion to the length of my skirt in some sectors.
7. Best of all the grocery budget can get cut at will!!

Yes! That's where the cap goes. Just be sure to connect the cap to the terminals "+ to + and - to -." My board is up and running and I'm very hwppy with the initial results. Now I'm messing with the pulse width and frequency trying to get the best top speed and the smoothest step-to-step operation of the motors. It's looking good so far.

OOPS, forgot to mention that your transformer goes in the "AC" terminals and the cap in the "+ and -" terminals . The transformer doesn't have any polarity , since it's AC - just use the two secondary leads that give you the 30 VAC output on your voltmeter. If the transformer has three secondary (output) leads, one of them will be a "common" and it will read approximately half the total output voltage when read to the other two leads. In other words, if you have three output leads, say named A, B and C, you will see half the AC output voltage between A and B and half the output between B and C. You want to use A and C leads - they will read the "full" output voltage on your meter. Just cap and stow the third, or common, lead.

Whoops, did I say that out loud?

No offence meant Sixpence... some of my best friends are female. My poor, male-centric thinking was influenced by the still relative scarcity of female techies ;-)

One thing I've learned is to test everything twice before committing to anything... at least I make less mistakes these days.

Bring up your power supply gracefully. Measure that all your voltages at the transformer primaries, secondaries, at the bridge, at the capacitor ... are all what you expect them to be... before connecting to your board.

This ritual helps keep the smoke in your electronics. This ritual works for building anything... test each subassembly before combining it to another ( already tested ) subassembly. It is the basis behind "Object Oriented Programming" and "Lego"

Peace, Gary

No offence taken I'm not the bra burning type. I do think I have made history by being the first to use the word 'bra' on this site. Thanks for all the help though. I now feel a lot more confident about connecting all this up without finger erasing results. Thankx again
