I just updated the code so if a MDI command is running the MDI button will not execute again.

A line was broken in the hal file maybe it is already fixed. Should give an error in the linuxcnc startup windowWhen it goes to safeop it usually tells why in the syslog.
Show us the last 30 lines or so from the command "sudo dmesg"
 

Aye, that it is.

i already follow minimal configuration adjust with my servo drive (SV630N), but still the servo doesn't move following linuxcnc sim, and status on my ethercat slave still SAFEOP for my servo drive. here is my hal and xml conf.

Hola, tengo un plasma CNC con la tarjeta mesa7i96s Estuvo cortando bien hasta ahora y de repente se desconecta pone que ha perdido la señal con la tarjetahm2/hm2-7196s.0: error finishing read! iter=309265 me pone esto 

I assume it is a cia402 drive.
Then the first thing is to try this minimal configuration.

rigth now, the error in my configuration has been resolved, and I can run the LinuxCNC sim using my edited hal/xml. However, my servo drive doesn’t seem to enter OP mode and can’t move the servo motor. I’m confused because there are no errors shown in the terminal, and I’m not sure where to start troubleshooting.

Bring it on, config errors are usually easy to fix.
Error messages, hal file and ethercat-conf.xml are needed.
In general, the ethercat drive pins are created with names from ethercat-conf.xml
Indices are from the id= entry, or if you have names= it takes that first.
 

Hello everyone, I got this machine through an auction, it is in good physical condition, but with a controller that, even though I have the parameters, will not perform referencing, simply the switch that supplies power to the drivers will not stick if I hold the z axis, it goes up to the limit switch, turns off the drivers and an error axis error appears. The motors are dc servos with analog input for the drivers and have 500 pulse encoders. my question is whether the Mesa 7i96s+7i77 can satisfy that the motors remain and that the rack ATC will somehow work later. Thanks in advance for your future support.

Thanks for reply. I was testing with a value of 200 instead 400 default.  Then i recognized the mdi commands are qeued, so there is no escape from executing every button press. Now i try something with a normal pushbutton and use the pythonmodul. creating a timestamp on each button press and get the difference, only execute the command if result is >=7. I am still testing

Thanks @Aciera
Finally got it working. Added Home Offset and Home Values to Joint_1 since it was not aligned as in documents and I cant give my arm that postion due to its hardware limits. So Accordingly defined Home and HomeOffset. and Small offset to J2 so that I remain horizontal. And minor offsets to J4. and Assiged Home location of J4 so that it remains vertical.
Thanks a lot.
Yes as @Aciera mentioned DH parameters are good.

125000 bits/sec. All LDCN network comms must start at 19200, then get upgraded.

One sets a servo update rate multiplier (e.g. 20x) so the 51.2 µs becomes only the control loop update time, but the commanded position is updated every 1.024 ms. Yes, correct - at 51 µs, the bandwidth would be insufficient.

If interested, I developed HAL components to initialize the LDCN, enumerate the devices, and expose pins to LinuxCNC. Like any software project, it needs experienced eyes to pick apart the architecture.

I am also trying to use servo from inovance, but I get an error from the configuration of the file where there are some unreadable pins. May I see how your file is configured or maybe there is a reference source that I can use. hope you still open this topic, thanks

@hanz24, Appologies, your profile got thrown out by accident. Feel free to reregister using your previous login data.

1. I don't see anything obviously wrong with your DH parameters
2. I would agree with @heaven that you are in a singular position. Which will lead to the inverse kinematics failing. In your pictures j5 is collinear with j3. Trying a different start position for j4 should help.
