Default Re: Copy Cad Help (Power Supply Problem ?)

my part is not that big, is it ?
It is too big for the original small kit. Your part size will be limited by either available power, or anode size.

= 60" is this correct ?
Your math is correct. Now, how big are the anodes?

Quote:
If I am correct then I now do have a power supply problem as my bench top supply only puts out 3.12A max.
That's enough for about 45 sq-in MAXIMUM using the old formula. You will be on the ragged edge of unacceptable plate though.

It's enough for 22-25 sq-in using the new formula.

I tried the piece this evening at my max 3.12A and saw a little fizzing for the first time, it turned out with shiney nice plate on a few areas but still dark on others
Now you are getting somewhere. Fizzing is good. A 60" part should produce quite a bit of fizzing. The patchy plate you describe does sound like your anodes are too small for the part.

I suggest you try a small part, well within the limits of your power supply and/or anode size, then you'll know what a good plate looks like.

Have you determined yet if you have the original or new formula? Did your kit come with a small AC power adapter? If it did, it's most likely the early formula. The new kit does not include a power adapter.

However, since you are getting kit in the UK, I don't know what the differences might be.
