That is true. In the videos, we are limited by the mill, not the
ARCNC100. The mill is a Taig with under powered servos. But still that
is pretty quick for a Taig. Look at the second Taig video on our page.
The straight lines are at 140 IPM peak on a Taig with small servos.

The ARCNC100 can output very stable pulse trains on the 6 axis
simultaneously up to 3.6MHZ (could go higher by a simple FPGA
redownload but we see no point yet)

The hardware is more capable in terms of future expansion. The FPGA is
much larger and the Central CPU is more powerfull at 32 bits 50MHZ and
more tightly integrated (it is inside the FPGA). It also has more RAM
and FLASH, more analog Ins and more digital outs.

The ARCNC100 is also completely standalone with user input and output
via PS2 keyboard and NTSC display.

It is a small standard NTSC monitor. Any TV would do, from the
smallest portable ones (like small DVD players) to a large plasma wall
unit. Anything with a video in RCA input or even if it doesn't have a
RCA input, a cable input with a $15 modulator will do.
