A few things I learned in hindsight... I should have made the Y axis
rails extend beyond the end of the water table enough so the torch head
could reach all of the water table. A little more Z travel would have
been nice. My slats are not rigid enough to keep thin material from
moving when

Hello,
I have learned much lurking on this list. Thanks everyone.
I have a pair of dell machines that _horribly_ failed the max jitter test
initally. Now they rank with the best in the comparison table. The
difference? Turning off the serial and parallel ports in the BIOS.
This works for my

The fundamental problem with a RepStrap made from a typical milling
machine is speed: my rather customized Thing-O-Matic prints reasonably
well at 30 mm/s and makes rapid motions at 250 mm/s.
Interesting comment - my KX1 config is not with me, but as it has a Gecko G540
and runs 48v
I regularly run my Thing-O-Matic at 120 mm/sec while feeding (I can do 160
but the quality suffers), and travel at up to 200 mm/sec. Most older ToM's
and cupcakes ran at 30 mm/sec, since the earlier firmware did not use
acceleration, leading to missed steps at higher speeds.

They tend to produce better results below 30 mm/s, mostly because the
stock firmware doesn't use any acceleration limiting at all, and I've
seen some down around 10 mm/s near my

That certainly puts it in the running!
What are the acceleration rates on the dedicated machines?
Given my heavy custom build platform and 12 V stepper supplies, the
accelerations aren't all that

I don't have a downdraft table but I assume you will have to move huge
amounts of air to capture the dust from the plasma. Quite a bit of the
dust flies up from the cut point so to be efficient the table will need
to be completely enclosed to capture the dust. The amount of dust
depends on

ps: I have no experience with downdraft tables, and perhaps they are the cat's
meow, but I am skeptical that they could work as well as a water table. The
amount of force with which the dust is created seems like it would too great to
be carried away by a downdraft. But, this is just
