ALMOST set up.

It's positioned in the bay.  I've opened all the boxes, and checked 'stuff'.  This thing came with TWO height-setters, and even a completely-wireless hand pendant for controlling the machine.

I still have to assemble the chip-vac and pipe it in, hook up all the electronics and check them out, and run a surfacing pass on the waste board to make sure my leveling job is 'just right'.  But it's looking like a LOT of fun!  Heck -- if this new software is all it's touted to be, I might even convert the OLD machine to this new stuff.

Pic attached.

Hello

Nice machine !

On the gantry, it's the ball nut that rotate and the screw that is fixed ?

Do you drive it with Mach3 ?

Thanks! 

In all cases, the ball screws rotate, and the nuts are fixed.  The Mitsubishi brushless servos on this thing are so small they just-about disappear, and all of the Y-axis assembly (including the motors) is hidden under the table, anyway.

It could run under Mach-3, but comes equipped with Vectric V-Carve Pro, pre-installed and tested at the factory.

I WANT ONE. 

Nice machine.  A larger format 4x8 or 5x10 is on my long wish list.

Eddy,
I'm hoping I will like it.  It'll be a fairly-steep learning curve, because it has so many features.

We'll see!

I have to take something stupid I said back!  I said:
"In all cases, the ball screws rotate, and the nuts are fixed."

----------------------------

X and Z rotate the screws.  There are TWO servos on the Y axis; one at each X-end of the gantry.  The screws are fixed, and the servos are on the bottom ends of the gantry, where it curves underneath the table.

Darn, I hate it when I miss something that simple!

Yep rotating the nut instead the screw eliminates screw whip on very long screws. Only downside is that motor weight is moving and more moving cables.

Yeah.  It also eliminates the need for extra bearings that the heavy screws would need to properly support the weight.

Duh!

The motors on this rig are VERY small and light -- Mitsubishi brush-less servos.  I'll bet they don't weigh three pounds apiece.

Hello

and also, the inertia of the nut is smaller than the inertia of a long and big screw so fewer torque is needed to accelerate.

but I guess that rotary nuts are very more expensive that fixed nuts ... ?
