re:Compumotor Parts Update

Brian,

If you have to ask,...

A lot of the answer you are looking for depends on two things.

1) How did you come to purchase these bds/parts? (really means, WHY
were they sold/scrapped???)
2) Do you trust your experience/ knowledge to fix 'em ? (really means
WHAT is your goal???)

I sent you private email before and still believe that is your best
bet. Answers here are more for things that might also apply to others
on the CCED list.

1) Electronic parts come on the market for a number of reasons. Some
are "good" reasons (for our usage) and others are "bad" reasons.
(didn't I just type this a few days ago re: used machines :-)...)
Some are even BOTH good AND bad! It is good to wait for response from
Compumotor before deciding your next move. Are these parts outdated/
rejects/ early revisions/ poor performers??? Is documentation
available? Replacement parts? Others on the list may be able to
answer better than I, the usefullness of these specific parts.

2) Soldering is a skill, and like all skills, can be learned. Also
like other skills, it can easily be done poorly. UNLIKE some skills,
it can "look ok" (to an inexperienced eye) and PERFORM poorly! Are
you up to the learning curve??? What do you want? Are you looking for
experience, dollars, parts for your own machine...?

Two things to consider here. First, many pc bds are manufactured such
that different parts are placed/ used to accomplish different
results. (Stepper drives with or without an onboard oscillator are an
example. Also the Gecko "pulse multiplied" boards, although this is
the addition of an "auxillary" bd; I don't know if Mariss changes any
other parts) Second, due to the "human" element of board design and
implementation, sometimes the parts on a board are changed or removed
(or "jumper" wires added, sometimes UNDER parts and difficult to find
or see!) because the board did not work as originally designed.

So, this may be just a case of "stick in the missing parts", from
your "inventory"... Or, it could get into a LOT more...

Good luck.

P.S. ONE thing you DO know is that you have a stockpile of parts
designed to be used in motion control, of some sort. If whole
drives/bds. don't work out, look to see if some of the PARTS can be
useful to you (capacitors/ transistors/ steppers/ etc.)
