that is kind of what I am doing. I am not running any CNC machines, I
am just 'messing' with some stepper motors, drivers, io boards and some
sensors
to see if i can make that contraption work. X-forwarding is easy,
because you can see if things work as they are supposed to, and it's
easier
i have run several machines through vncviewver server from realvnc, and
done debug several miles away. DO IT!
In the past I tried to evangelize many people into LINUXCNC, but the
windows virus does not cure easily.

Maybe not to few, I would expect low efficiency.

Cable and wiring needs will vary from application to application, but where
I've had to replace machine cabling I have usually used Igus' Chainflex cables.
But I'm generally working with large cnc routers with long cable runs (3m or
so) and a lot of long moving cable chains where good
FreeRTOS sure is popular. Have you compared it to other open source

Any thoughts? I haven't worked with any real-time OS's much since the
80-90's.

It is a 3W 120V motor. It’s going to eat milliamperes.

Gene, Criticism is good. I am most critical of my own work, the only why
to not get stuck and improve.
Linus CNC is basically a 1980's software design. It has some rather huge
faults. The real problem is that no one was time to do a full-up rewrite.
Back in the 1980's computers were

Hi all;
For once I'm writing to say thanks to the developers for making the
homing sequence quite flexible. .
As I get older I tend to use the KISS principle more and more. I'm

I'm sure it's a coil wire.
Usually the frame wire is bolted to the ... frame.

LinuxCNC supports a number of PCIe interface cards.
