So, just came across this today:
http://www.centroidcnc.com/centroid_...ontroller.html
And, honestly, trying to figure out why everyone isn't freaking out about it? Seems like the answer to a lot of prayers in the DIY CNC world. What am I missing?
Regards,

Ive been looking at this myself as I'm building a new machine and I really don't want to use mach 3 or 4. I should have stuck it out with eding cnc but this does look interesting.

I am just a happy hobbyist so take my opinion with a huge pinch of salt.
This did not look attractive to me because of gcode limitations and only 3 axis in cheapest software option.
Also the GUI does not look intuitive for me..
Im not using mach for my future machine, went for uccnc instead. :)

The two things that standout to me, are you need to add the cost of the software to do anything more than basic machining, and outputs/inputs are limited, with no obvious way to expand.

That's fair - I may have overstated a bit. Also, I was thinking that this was a standalone controller similar to the DDCSV1.1, but now I see that it only works in conjunction with their software.
Still intriguing though. I really do not like depending on Windows PC for realtime functionality.

With the exception if Mach3 running on a parallel port, just about all hobby controls rely on their motion controller for the "real time" stuff. Windows is not an issue at all. I've been using machines costing well over $100,000 with Windows based controls for nearly 20 years, and I've never seen Windows cause an issue.
I would not want a machine control that didn't run on a PC, as you lose all of the advantages that having a PC at the machine brings.Gerry

There is no perfect control for everyone. If there was, then there wouldn't be so many different ones available.
I just don't see the Acorn as the holy grail of cnc as so many other do.
There are other controls that offer more, for less money.
The Acorn has some advantages in some areas, and others have advantages in other areas.
If the Acorn is what you're looking for, than by all means go out and buy it.
I decided to go with UCCNC, which is a better fit for me.
My UCCNC setup (UC300ETH + UB1 breakout board) is roughly the same price as the Acorn with the $99 pro level software.
The Acorn gives you 4 motors, UCCNC gives you 6.
The Acorn has 8 outputs, the UB1 has 14.
The Acorn has 8 inputs, the UB1 has 23 + 2 analog inputs.
The Acorn does have software advantages.
UCCNC does not have rotary axis support at this time. It will eventually, but it might be a year or two.
UCCNC does not have screw mapping.
UCCNC does not have cutter comp, but it will soon, as it's been under development for a few months now.
I believe that the Acorn is much better at digitizing, but it's limited unless you buy the $499 software upgrade.
It all comes down to what you need from your control.Gerry
