Re: [CAD_CAM_EDM_DRO] home vs. industrial PC..

Hi Jens:
Have a look at what Light Machines is using for their PC.
Defiance (a now defunct competitor to LM) used a real basic Office Depot
style Pentium
and stuck a proprietary motion control board in.
I always considered it to be a "serious machine", and so does everyone who
comes into my shop.
I've run my Defiance under horrendous conditions for over 4 years now, and
never even a burp from it.
Commodity PC's are so cheap now that it's hard to emotionally justify going
with the industrial stuff.
Just as an example...I bought a Haas Minimill, and had a floppy drive put in
it...600 bucks for the drive.
I damned near cr***ed my pants, not at the price , but at the PERCEPTION
that I was being ripped off.
It took a couple of calls to Haas to calm me back down.
Put a big disclaimer on the unit when you sell it advising people that they
need to keep it clean on the inside, and you're in business.
Doing ALL that it takes to keep the dust out reliably is a fools hope, and I
don't believe the other concerns about robustness are really valid unless
you intend to mount the computer directly onto the machine frame without
isolation mounts, and then hog all day with big carbide facemills.
Cheers

Marcus

hi group

a company asked me if i was interrested to build 8-10 copies of my
homebuilt router for them, after have seen it. now, this machine is
made of hq parts only and the heart of it, an industrial panel-pc is
v-e-r-y expensive (it runs flashcut with the black-box). my problem
is that the specs for this pc is a little to low, or on the border
line to run flashcut v2.0. the fastest cpu available for this
particular board is a 1.2 gig celeron. so, in order to take the full
advance of fc, i now have 2 options:

1. wait for a new upgrade/release of the industrial-pc (the complete
unit costs around 2300$ today)

2. use an ordinary home/office pc with higher perfomance and 1/4 of
the price, and parts available in any radio-shack.

whats the advantages with an industrial pc one may ask? honestly, i
dont know. i was just told by some engineer that its a must-do.
i do know however, that they have a thicker circuit-board and more
layers of surface protection/treatment, so they can stand vibrations
better and someone claimed that the powersupply is more reliable.

still, ive seen a lot of "home"-pc´s on the shop floor covered with
s**t running year after year flawless.

so, my question to all of you is, can i sell my machines with a built-
in standard pc, and still consider it a serious machine (the monitor
and keyboard is industriual, though)
