We were using Mesa's 7i34 as the pulse/encoder interface to servo drivers.
It was okay in one workshop with Hypertherm 45A plasma cutter. But, it
failed in another factory with 300A plasma cutter and large EMI noise
around that field. Our USB/FPGA link

They tend to produce better results below 30 mm/s, mostly because the

Have a full-size water table, but have lift-out slats and a

You would probably leave the machine configured 2/3 slats and 1/3

We then developed AR02 in replace of 7i34, and it solves the EMI noise

Hi Viesturs,
If you are mainly planning on cutting aluminum I would suggest looking
into oil mist cooling instead of flood coolant. You only need a trace of
oil in the mist to act as a lubricant while the air clears the chips and
cools the part. It works very well. You can get vegetable based

Some research I've done tells me that most people just set the varispeed head
to ~3300 RPM and use the VFD for speed control, but I'm trying to go all out
and have total control. They even run it to 5500 RPM, but I'm not sure I want
to strain the spindle bearings that much.
Let me give

I converted my Boss 5 to PC based, 220V single phase power. I kept the
stock steppers.
Here's a quick parts breakdown:

Antek 48V toroidal trasformer AN-10248 1000VA
PMDX-135-8020 20A power prep module
Relay Power Supply:

Still looks like 25 seconds/layer or thereabouts. Certainly a big

over earlier designs, though.

Mike,
Awesome. Thank you for the download.
I'm considering using some surplus Parker OEM750 drives on mine, but will take
a closer look at the Gecko hardware.

I'd just add that I did this conversion, with the geckos, and the
machine moves very nicely.
