Nothing on the screenshots says it is a fully preemptible kernel in use, and it is also noted by LinuxCNC in the terminal saying "using posix non-realtime".
Why the report? You already said that here and it was not changed (the tittle) as there is no evidence the normal AMD64 kernel also does the same thing, both screenshots contain only Orange PI.
Instead, try patching the kernel again and choosing fully preemptible in menuconfig (was it called that?) ... but then again, why patching, there are ready made debs for AMD64 with RT patching already done, no idea if there is one for OPI though.
AMD64:
packages.debian.org/experimental/amd64/l...c6-rt-amd64/download
Nothing for AARCH64 though.

It is not an error as noted on the warning, well not always, so you do need to test on a machine or use a DVM to check the output pins on the parallel port connector.

You are correct.  I forgot to sudo the first time.
I did try to run LinuxCNC with the new address.
I got the same error with the new address.
The demo runs.  Computer is not connected to the mill so I don't know if signals are going to the port.
Thanks for your assistance. 

 

There are some precise water leveling systems like these
www.precisiontools.biz/tools2/pwl/
www.wylerag.com/en/products/communicatin...icating-water-level/
www.wylerag.com/fileadmin/pdf/manuel/Com...g_Water_Level_77.pdf
They follow the curvature of earth so there are pretty accurate
for linear leveling ways when build up a machine or machine leveling...

Because water is polar molecule there is surface tension between water and hose-cups so if forms meniscus at the edge
but because cups are 50mm x 50mm meniscus formed only at the edges of cups and not in the center.
Addition of surfactant to water helps to reduce water tension.
A micrometer with a needle attached to it probe water surface and detect
differential height between surfaces.

Can resistance probe modified and used in Z axis instead of micrometer
to detect touch with water of other liquid?
This will be very simple to level machine and machine ways
with very much accuracy without special instruments.
Dro of Z will show the height difference instead of micrometer and detection
touch of probe with liquid by vision.

Because deionized water has more consistent density and DI water is not conductive
so resistance probe will be useless can be used capacitance probe ?
 

It should be here

Aciera,

I shot Peter from Mesa an email and he responded saying that I could custom configure the firmware for the 7I96S using the 'periodm' command to read PWM signals. He said that redefining one of the encoder inputs would be best. I will post here as I learn more. Here is the info on said command:
linuxcnc.org/docs/scratch/html/man/man9/hostmot2.9.html#periodm

I believe that I can re-flash from the terminal on my machine. I will probably run the firmware past Peter before flashing.  Here is a couple links that explains re-flashing. Tommy has posted on one of them, perhaps you can weigh in..
forum.linuxcnc.org/38-general-linuxcnc-q...ashing-mesa-firmware
www.forum.linuxcnc.org/27-driver-boards/...a-card-7i96e-and-7i8

Does anyone have a source for the standard firmware that comes on the 7I96S? I need a base software to modify.


About M52. I should be able to edit my GCode post processor to add M52 P1.  Modifying the post processor is not too difficult using Visual Studio Code.  I assume this just needs to be posted once at the beginning of the gcode file to put the machine into adaptive mode? And maybe once again using P0 at the end to turn it off..  I can have a separate post script for EDM.

I haven't had a chance to do any research on running a PID loop inside of HAL yet.  I plan to do that and will respond here with questions and comments.  I think I should be able to figure it out using a combination of the LinuxCNC resources and ChatGPT.  I am currently out of town for thanksgiving and will not be able to test anything on hardware until I get back. 

Best,
-Dylan

In addition to setting the PWM mode to up/down, you would need to change some names:

ORIGINAL

net Xpwm pwmgen.0.pwm
net Ypwm pwmgen.1.pwm

net Xdir <= pwmgen.0.dir
net Ydir <= pwmgen.1.dir

net Xdir => parport.0.pin-02-out
net Xdir => parport.0.pin-04-out
setp parport.0.pin-04-out-invert TRUE
net Xpwm => parport.0.pin-03-out

net Ydir => parport.0.pin-05-out
net Ydir => parport.0.pin-07-out
setp parport.0.pin-07-out-invert TRUE
net Ypwm => parport.0.pin-06-out

To something like:

net Xup pwmgen.0.up
net Yup pwmgen.1.up

net Xdown <= pwmgen.0.down
net Ydown <= pwmgen.1.down

net Xdown => parport.0.pin-02-out
net Xup => parport.0.pin-03-out

net Ydown => parport.0.pin-05-out
net Yup => parport.0.pin-06-out

Note that you may need to change the sign of the PWM scale or swap the up,down
parallel port pins to get the correct feedback direction.

oh, thats good to know, I will try that in the morning when I am at the shop.

Thanks.

I have only edited the file in LINGUIST, do I need to do this step from howto?

If any text changes are made to the GUI then run the following to create a GUI python file:
$ pyuic5 ../qtplasmac.ui > qtplasmac.py

No, you only need to do that if there are any changes to the original English version so the changes can be added to the translation.

What is the file that you attached, there doesn't seem to be any translations in it.
Can you post the .qm and .ts files as a zip file.

if (when linuxCNC is running) you run

halcmd show all  | grep 7i77

You can get all 7I77 sserial pins and parameters


 

But setup is kind of strange. For same pc on debian from iso list, i needed to nohz=off and nomideset to get 22-25 delay.and isolcpus=1. Here only the latest one. With two other system is slugish and result is worse. And i have lpt on pcie card. I can see it, but it does not show error if any other adress is beeing used. Normally xe000 is shown in lspci.

Also on i have left speed step on in bios. If turned of - cpus is at 800 mhz all the time. Strange..

HaHa Don't I feel stupid. I guess that's how my day has gone. It didn't even occur to me that [] meant put in your own value
Now to look even more stupid. How many channels does the 7i77 have, and how do I know what is on each channel. Is it a channel per drive or just i.o on one, drives on another, encoders on another and so on. until earlier today I didn't know there was more than 2 and I didn't really know they were channels of the card I just thought that was the address of the whole card.
I have alot to learn.

[card_ip_address] = Mesa FPGA card IP address, so likely 192.168.1.121 or 10.10.10.10

If you don't get analog output, (and there is some non zero aout value),
its likely appropriate analog enable is not true.

Note that the 7I77 has a common enable for analog  channels 0..4 and
separate enable for channel 5.
 

Thank you, i will add this to the original post in case anyone needs it.

Hello, my name is Daniel and I am from Argentina, can someone help me modify the configuration for etch servo via parallel port? I want to do some tests of its operation. Currently I have the HAL configuration in 1.1 mode but my h-bridge works pwm up, pwm down, I think I have to change to 2.2 mode but I don't know what else I have to modify.
Configuration attached.
Excuse my English, I use a translator.
Thank you
Greetings
