Is there a simple conversational way in Linuxcnc (2.5) to cut a straight line

I think you are in trouble since the top 4 hits on google for "building
rtai on debian" go to linuxcnc. I have built many RTAI kernels, but it was
always painful, and it has been long enough that I really would rather
change operating systems.

Mine looked very similar. My control had a CRT and could hold a short

Is there a more up to date tutorial on how to compile rtai with
Debian.It took me a whole weekend to compile a kernel that will
boot but when I try the latency test, I get
insmod: error inserting '/lib/modules/2.6.32-rtai/rtai/rtai_hal.ko':

ERROR: cannot load /lib/modu

They ran gcode just like any NC/CNC machine. Each linear axis had two
cylinders opposing one another. A hydraulic servo valve released pressure
from one or another cylinder to allow the table to move away from the high
pressure side.

Cincinnatti made the machine, Moog made the control. The control was
all pneumatic,
no interpolation, not even linear. It

Hi Peter,
well, I made a mistake, I was counting from up to down and analog0 is
forth pin from bottom. I test analog0 to analog4 and everything was
fine, for analog5 I did "halcmd:setp hm2_5i25.0.7i77.0.1.spinena TRUE"
and it works fine too.
Thanks for you help,

I used to drive a servo-hydraulic tensile-testing machine. The
actuator was extremely stiff and extremely fast. And _extremely_
expensive.
That particular one used a leaky piston
Yep, same here in the US.

I forget who made them in the USA - Cincinnati Milacron perhaps.
I found a company in India making them.

Hi,
I run the Ubuntu cd version 2.5 on my CNC mill (Optimum BF20L) and like

I retrieved from git the 2.5 branch, grabbed all the dependencies and

The standard PICO power supplies are designed to be run off a regulated
12 volt PSU, not a 12 volt battery.
Only the wide range units are designed for car use - and some of them
will survive an engine starting cycle which is handy since you PC will
not reboot when starting
the car, boat, etc as

A month ago I needed to add RAM to my modeling PC and then 204-pin
memory actually was cheaper.
