Looks like they are Chinese.

This thing is simply awesome.....

Looks awesome but I guess it will be out of the price range of a beginner like me.
Something to aspire to in the long term.

One thing that I don't understand is the stopping. When I drill I always have the bit rotating as I remove the drill from the hole. Otherwise it is likely to get stuck in the wood or at least potentially put a lot of rotational force on the wood as it slows down.
Is that just because I am not using a drill press and thus not holding the drill straight enough?
I appreciate that a stepping motor could stop extremely quickly but would there still be a tendency for either of these problems?

I can see how it might get stuck if the hole is not clean but doubt it will put any more rotational force on the wood as it slows down than it did while drilling the actual hole

Yep.

Rotating the bit backwards when backing out has some +/-.

The good thing is it maintains downward pressure on the work thus reducing the possibility of the work catching and riding up the bit.
OTOH, if bit catch, especially cheaper ones, they are not as strong running in the reverse direction and can even break.

I do use reverse drive sometimes on my drill press to disengage stuck bits, mainly when using bits larger than about 1/2" diameter in metal but I do this under very slow speed while raising the quill.
Sometimes the reverse drive only needs to be run for part of a turn for the bit to become disengaged.

Bits getting stuck can usually be traced to other factors like blunt bits or too high a pressure/ feed rate.
Slowing the pressure/feed rate down as a bit breaks through the bottom surface reduces the chance of a bit driving through the thinner surface and catching. Using a sacrificial piece on the underside also helps.

Hi Dave

Popular woodworking has done a partial review of the machine. a couple of observations / comments in the review

• “digital variable reluctance” (DVR) motor with speeds from 50 to 5,500 revolutions per minute,
  
• the motor maintains your selected speed under load to keep it from stalling.
• You can set the bit depth (up to a 6″ quill travel) with a traditional post-and-jam-nut arrangement,
• or set the computer to stop the cut at your preferred depth (in increments of 500ths of an inch). Lower the bit to touch the work, then zero the quill depth. Save the settings. The bit will stop cold when it reaches your chosen depth (and beep to notify that you’re approaching bottom).
• when using a Forstner bit with this function, you’re left with a little flag of material in the bottom of a stopped hole – but that’s easy enough to clean out

the full review is here NOVA Voyager DVR Drill Press - Popular Woodworking Magazine

I emailed Carbatec during the week, to see when these were coming out as they are being released in the states soon

The are expecting them February with a $2400-2800 price tag for the Aus 2HP model.

Looking forwards to seeing them in action

Some nice features, but two observations:
*It seems very low (I.e. the pedestal is too short)
*The buttons on that keypad aren't going to last.

You have seen one?

Isn't that it in the video you linked?

Its hard to judge the buttons until you see it, I've used commercial grade machines and they have had buttons like his and were fine in a commercial use.

As for the height, 1794mm is fine, and more ergo friendly than the high models that are out there.

but this is all speculation, until we see it and use it in real life..

i know i want one.

To condemn the buttons I thought you must have used one.

It looks quite short when viewed next to the guys in the video. Maybe it's just the perspective, but I prefer the table to be closer to eye height. Saves me crouching over to align the workpiece.

My experience with that type of button (don't know what the proper name is) is that the plastic overlay splits and exposes the contacts underneath. My fingers are always covered in some sort of contaminant, be it glue, cutting oil, grease, etc. If they are of the quality that Bryn has experienced, no problem. If not, it could be a very expensive repair. And I don't think looking at them in the showroom is going to tell you much about their likely longevity.

Don't get me wrong, I love the idea of a belt-less drill with such a wide RPM range, but I don't think I could stump up $2800 for that one. Looking forward to seeing it the flesh though.

Based on the specs and photos, the DVR drill press uses a similar controller to the Nova Galaxi DVR 1644 Lathe.

A search should reveal if the buttons on the lathes have a durability issue. Which would sort of curtail speculation like Jack's
