Hi Guys,
I am hoping someone can point me in the right direction. I have a TangBOB board that I am trying to get a N4D3E16 MODBUS board (16 Digital In - 16 Digital Out) to work with.
This board will only allow Function codes 3 (Read Status) and 6 (Control Command).
I have all 16 inputs working well through to LinuxCNC, but I can't get the outputs to work. When I configure RIOCore to use function 6, it seems to assign it as a float, and so in the testgui it shows up as a slider.
Attached are a couple of pics of my configs and a page from the modbus boards manual.
I am hoping someone here might be able to point me in the right direction here.

Thanks
Andrew

 

you can use the serial commands with a terminal like picocom.
try picocom -b 115200 /dev/ttyUSB0
But the spiethconfig does not work. Use the default settings

Thank you for the reply! Sorry for the perhaps stupid questions, this is the first time for me with linuxcnc, ethercat and linux in general basically...

However I guess that means that the Etherlabs people have to do some kind of update for it to be compatible?

I guess I will continue on the 6.1.69 image from Cornholio then. I was able to update it to lcnc 2.9.4 and install ethercat through you guides (would not have been possible without them, so huge thank you!), and I guess it does not really matter to have the latest kernel right?

my bad. seems its not compatibleBuilding initial module for 6.12.11
Error! Bad return status for module build on kernel: 6.12.11 (aarch64)
Consult /var/lib/dkms/ethercat-dkms/1.6.2/build/make.log for more information.
dpkg: error processing package ethercat-dkms (--configure):
installed ethercat-dkms package post-installation script subprocess returned error exit status 10Possibly report a issue in Etherlabs gitlab

try:
sudo apt install dkms

dkms should be a dependency of ethercat-master
maybe it needs installing manually on the pi

Give Brad a call. He's looking for some Mesa stuff and is in QLD too

Hello everyone,I have a question regarding uploading the Remora config, as the config upload runs into a timeout.

To explain: I am using an EC500 board flashed with the latest Remora CPP version. Uploading a new config has worked flawlessly multiple times before, but ever since I switched from Ubuntu Linux to the Debian LinuxCNC ISO, it no longer works and results in a timeout.

Reflashing the EC500 works without any issues. The board can be pinged and used without problems. However, the config upload using upload_config.py does not work.Has anyone encountered this issue before and maybe has a tip for me? I know that I could theoretically compile a modified config into a firmware build, but I would like to get the upload function working again. 

Thanks and best regards!

Hello,I have 4 new (never used. In the packet) 6i25 7i76 cable pug and go kits for sale if anyone is interested.  I'm in North Queensland, Australia near Cairns.  There are 3 in this photo and i'm pretty sure I have the other kit in my draw at work. Thanks,Chich
 

Hi Hakan, thanks for saving me again!

If can be useful to someone, for a 40K spindle ended up with :

loadrt scale count=1
addf scale.0 servo-thread
setp scale.0.gain 0.000025
net spindle-M3 spindle.0.on lcec.0.SPINDLE.aout-0-enable
net spindle-speed-scale spindle.0.speed-out scale.0.in
net spindle-speed-DAC scale.0.out lcec.0.SPINDLE.aout-0-value

ok,
 I just found on the subject the config page on the github github.com/SybexX/ESP32_LinuxCNC_MotionC...in/SerialCommands.md,
 I don't understand where you have to type the commands to configure the card?

Hello,

I tried to figure that out, but not really successful, so I spam the forum with the questions. (I have the feeling I should have found the information somewhere; maybe someone can point me in the right direction) 
I have a 6i25 card with a 7i76 card connected to my PC. Some stepper motors are running and can be moved with keyboard, a basic configuration is running.

Now I got stuck, trying to hook up the old BLDC driver (labeled TONMAN Brushless DC driver) or the machine (which I have no documentation for) seems not to run with an analog input. 
I tried to connect the Spindle interface somehow, but it does not want to run.

There is a pair of pins labeled +- (PWM / ANNA), but I think it is not really for analog input signal.
Hooking up a potentiometer (allowing to create a voltage between 0 and 5V) does nothing to a certain voltage. At approx. 2.6V it switches from "off" to "full speed".
I tried one of those PWM generators   which works fine. It allows to control the speed of the motor, no issue. I can adjust the motor speed by setting the duty cycle to anything between 10% and 100% and it seems to be what I need. 

Now the questions: Is it correct that in my situation the spindle interface of the 7i76 is just the wrong choice for my BLDC amplifier?
                                How do I make a PWM control for my spindle with the 7i76 (6i25)?
                               
Greetings Timo



 

Hello everyone, I have a situation and maybe you can help me with some ideas:

I am using limit3 to control an extrajoint, on the machine control panel I have two buttons which work as busy hands buttons, that is, for any movement of the machine they must be pressed and when they are released the machine must stop and when they are pressed again the movement must resume.

Using the motion controller "motion" I solved this with feed-inhibit, but now using limit3 I don't have this option.

Doing some tests I have enabled the limit3.enable pin with the action of the buttons but limit3.out is zero when enable is false and that is not what I need, I only need it to brake.

Another option I have tried is to use a mux2 so that when the buttons are pressed a speed change to zero is made on the limit3.maxv pin, this is the closest I have been to achieving this behavior, I am not sure if this is a good option.

I appreciate all the ideas, greetings and thanks in advance.
