Hi Alex
Do you mind saying what you are printing, and if you feel the printing is a

but they only seem to be able to produce junk. Cnc'ing it out of a block of

John, I can tell you for sure that the parts end up being much
stronger than you might at first guess from being printed hollow.
That isn't to say that they are indestructable -- but I was skeptical
at first, too. The application you mentioned is actually perfect for
3D printing -- the various

Those both show an isolating transformer with a bonded neutral on the
secondary side as well as a line filter.
Is the isolating transformer depicted a delta wye?
It's drawn as a Wye-Wye, but I don't think that is at all important

Hi John,
Sorry for the delay - just got back from a meeting. I also updated my
email address so I can post again!! My ISP moved to Google services and
my
email address changed. The EMC list had blocked posts sent from my new

I'm guessing your 2.5 facing mill may not be rated at
Roland, in your view do you see EMC being a CAM software?
It actually isn't.
Also you don't necessarily produce better parts using a 2.5D mill, remember a
3D printer is a Milling machine, the only thing different being the spindle is
now a deposition head of some form.
Really you will only

Try the RepRap open source printer, last i checked you can buy a fully built
machine for about $600. Also it is open source.
Have you ever broken a plastic part?
With a 3D printer you can fix things, dream and make your dream real.

That sounds like the tapping you needed.

the machine with a long, dry stick :-)

Well, have you checked on CNCZone for any experiences with this system?
maybe somebody there knows how to fix this problem. there are some VERY
savvy machine

As an electrician, I should now interject that a neutral should only be
bonded at the point of distribution (the breaker panel or upstream
transformer). Grounding a neutral anywhere else makes for strange
problems and stray currents on the ground. People often falsely assume

Hi Roland,
To the average machinist - ok, ALL machinists, the parts produced by
homebuilt FDM machines look awful. There is visible banding along the
Z-axis, variations in the amount of plastic extruded, occasional slumping
at overhangs, and places where support material had to be snapped off.
