I have buster installed and
rtai-modules-4.14.148_5.2.3-linuxcnc_amd64.deb
I built linuxcnc, running the buster rtai kernel, from the git sources.
dpkg-checkbuilddeps found most of the needed packages. It missed 5,
bwidgit, libtk-img, tclx, python-gtk2, and python-yapps.

John, I'll be uploading some pictures and video with pleasure. This machine
is a Mazak lathe that we should have retrofitted to LCNC a year ago, but
because of lack of time and a lof of work we had to postpone. The lathe
itself is working fine (we only replaced the spindle drive and monitor) but

Looking forward to seeing some photos.

By the way, the board is the 6i24-25. I don't know if I pointed out that
earlier.

Well, today I purchased the 7i52S to finally have my setup completed. I was
checking the spindle manual today and I found it can be driven by pulses
too, so I don't need to have an analog out for that. That takes the 7i33
out of the game for this machine.
So to sum up, this is how is going to be

Upgrading to buster was successful.
I got the RTAI kernel installed.
linuxcnc has dependency problems. It wants python-vte, which wants
libvte-common=1:0.28.2-5. libvte-common=1:0.28.2-6 is on the repo's.
If I install libvte-common=1:0.28.2-5, it breaks other things...

The parport driver offers a "reset" function that sets selected pins
back to zero. You can run this later in the thread than t

In the past, I have had a reasonable amount of luck reducing real time
delays by building a custom kernel. Not sure if those kinds of gains are
still possible. And it's a lot of work unless you are using realtime
preempt.
As far as Gene's problem with the beep, they are probably using the 8051 o

The system can send a maximum of one pulse per base period.

I think I would do the install one at a time, (kernel then RTAI then
LinuxCNC then docs)
apt-get in
Changing from the 'Latency Warning Messages', thread,
I plan to test upgrading stretch to buster rtai. The steps are:
1. Fetch the RTAI deb's into ~/RTAI:
cd ~/RTAI
wget http://www.linuxcnc.org/temp/linux-headers-4.14.148-rtai-amd64.deb
wget http://www.linuxcnc.org/temp/linux-image-4.14.148-rt
Thanks I try to ask on forum not see that thread previously. I
read now but not see things that can help me.
I make somethings of similar with modbus work well but there is not a
fast response with (max 50ms) someone suggested me sdi bus but is
not my ideas ... so that the

That's fairly terrible.
Out of interest, how well does that machine work with Mach3?
