Describe what you have, both hardware and software.
Best is to show a short assembler code Or MikroPascal
code if you have to) that shows your problem. Regarding the
gardware, tell us *all* components and how they are connected.

Loaded using what ? What programmer ?

There might be some here that actualy know what a "PICAXE" is
(Well, I do know what it *is*, but that's all). You'd better focus
on the new circuit and try to get that running.

And how are your CONFIG settings ?

What "pin" ?

"Drive" from the PIC code or from the outside ?

What is "swicthed quick" ? The power or the pin ?

What is "stepping" ? The pin ? And what *is* "stepping" ?

Help yourself by a better description of what you are doing... :-)
What does the hardware look like ?
Some pre-made development board or have you wired it up
all from scratch ?
