The Kearney and Trecker has at least 96 i\o and 5+ analog axis. Everything

Hal and one poorly written realtime component to do the spindle shifting.

The pay walls, axis limits and markups on accessories are the reasons I

The thing I love most about Linuxcnc is the flexibility, reliability and

My first experience on a retrofit was on the little sister to the Blue

When I had the first one up and running we had a Fanuc tech in the shop

I used to want a Denford ORAC but I found a forum thread where someone took one
apart to refurbish it and it's just a modified clone of the EMCO 8x20, which
has also been widely cloned as the common 9x20 with a 1/2" increase in center

That's true!
And MACH2/3/4 has a huge user base without ever needing a command line editor.
So if it can be done for Windows then certainly it can be done for LCNC.
that deep, they are already using LCNC.

The problem that is limit
My first experience with NC/CNC was in 1978 on a 1958 Cleereman VMC with a
GE Mark Century 100 control. That makes the technology over 61 years old.
The control enclosure sitting beside the machine was 6 X 6 X 5 feet. The
cooling unit was a LARGE household AC window unit. There were 100's of 4 X

I agree that an iPad or tablet appears to be an excellent user interface.
The motion controlling portion is the only portion of the code that needs
to be synchronised.
Real-time operating systems can be used or the playback approach
are alternatives.
The advantage this group has is assisting
Hmm.. so the realtime patches being integrated into Linux kernel is
worthless old technology? They are waisting their time? (This is
unrelated to LinuxCNC)
Currently LinuxCNC is being added to debian testing. It will soon be part

The problem that is limiting LCNC's wider use is that it is a very old
design. It is definitely not what anyone would design today. And it is
not what moderned users expect or want. Documentation i=will not change
what it is.

There are some case studies in the Wiki. However these are probably rather out

Because linuxcnc is so flexible - I actually did some testing between mach3

challenge in using a Linux based solution. It's a new TV remote with
different colored buttons.
My concern is the precision of the resulting work using a solution that

I love that LinuxCNC is hacker friendly and can be customized as needed,
but I also think it'd be great if there was a simple generic
plug-and-play solution for a 3 axis mill or router and another for a
lathe. It's all some people would need and it'd go a long way toward

I think it's a great idea, I've had a lot of the same thoughts in the
