General Questions about using ethercat

Category: EtherCAT

I have linuxcnc loading but the steppers still won't move.  Ethercat Slaves shows drive is in OP mode, but when I use "ethercat upload" to check drive parameters, I see that the drive is not in CSP mode.  Where is this supposed to happen?

Troubles to get started with SD240 Retrofit

Category: Turning

You are missing the "servo-thread" for the "jogincr" component

that is:

addf hm2_7i80.0.read servo-thread
addf motion-command-handler servo-thread
addf motion-controller servo-thread
addf pid.x.do-pid-calcs servo-thread
addf pid.z.do-pid-calcs servo-thread
addf pid.s.do-pid-calcs servo-thread
addf jogincr
addf hm2_7i80.0.write servo-thread

should be:

addf hm2_7i80.0.read servo-thread
addf motion-command-handler servo-thread
addf motion-controller servo-thread
addf pid.x.do-pid-calcs servo-thread
addf pid.z.do-pid-calcs servo-thread
addf pid.s.do-pid-calcs servo-thread
addf jogincr servo-thread
addf hm2_7i80.0.write servo-thread

That is a realtime network error.

1. Have you run a latency test on the PC?

2. What s PC hardware is being used?

3. Have you disabled all power management in the PC's BIOS?

4. What is the result of the command (typed in a terminal)

ip a

?

If something needs 12V and 5V DC, having a 12V power supply and a 5V power supply with a common negative—effectively a single power supply with two output voltages—might make sense.

If the power supplies are powering seperate things, probably keep them isolated.

It all depends.

There are (often) cases where negative sides of power supplies must be wired together, but usually not at the power supply, it is done on equipment from one part to another. This avoids loops and keeps stuff at the same potential.
There are cases where this is not allowed at all.
So the short answer is yes and no, you have to know what you are dealing with to know if this can be done or not, and is not something you can just read on the internet, it requires deeper knowledge of the subject.

It is easier to answer if you give us exactly what you need to do.

If a power supply has a ground/earth screw, connect it to electrical ground.

A metal chassis should also be electrically grounded.

But power should be isolated.

User error or a strange event on probing. Broken ruby tip.

Category: QtPyVCP

I was not implying there was an issue with the subroutines. While I don't use them as much as you, I have used them quite a bit without any problem. Additionally, my machine is a Bridgeport BOSS, which is quite rigid.

Having a log would provide the facts of what really happened, rather than relying on what I think I saw. Again, as probing has worked flawlessly, I was not 100% focused on the details. It looked like it triggered on the Z and kept going. I always test the probe connection prior to probing, with a manual trigger. So knowing if it triggered, how many times, the feedreate and movement, in chronological order, I could solve this definitively. I was thinking of saving the last 2-3 probes and rolling the logs so one the past probing, but not wasting disk space

No creo que sea real, pero lo pregunto los negativos de las fuentes de alimentación de diferentes voltaje hay que unirlos entre Ellos. También había escuchado algo sobre que todos estos conectados hay que llevarlos a la tierra AC Que me parece mal también, pero no entiendo así que lo pregunto. Gracias

EL2502 and EL2535 PWM Ethercat BECKHOFF Modules

Category: EtherCAT

Hi, I'm also looking forward to your conclusion because I need EL2502 too. Besides PWM, I also need duty cycle to controll a laser.
Thank you

Axis 2 - touchscreen version of old friend

Category: AXIS

Hello,
i think there is an error and think it must be:

sudo chmod +x /usr/share/axis/tcl/axis2.tcl instead of sudo chmod +x /home/donno/Downloads/axis2/axis2.tcl
(third line with sudo)

[b][b][b][code][b][b][b][code][b][b][b][code][b][b][code]I tested this on Linuxcnc 2.10pre and works great !

Maybe add a readme.txt in zip with instructions to install ??

Troubles to get started with SD240 Retrofit

Category: Turning

Probably important: the connected enconder is a 1000 increments TTL encoder connected to Enc3 on the 7i33 and in Halshow I could see the counts in/decreasing when turning it left/right- so it seems to work in principle and is recognized by LCNC
And I would for the moment want to be able to move the axes by handwheel without having to home the axes before.

The whole setup is  a 7i80hdt-->7i33-->7i37

Troubles to get started with SD240 Retrofit

Category: Turning

Hi, though it seems to be rather a monologue I have still not given up  .  Ok mean while the error was found- the repaired 7i33 unfortunately still was not working correctly.
Now I have the two axis working properly and smoothly and would want to be able to implement a shared handwheel for the X and Z axis.
Therefore it was recommended to do a second config file with PC-Config and copy the necessary lines to the original HAL and INI files, sonot to overwrite the original config.
And so I did. But obviously I made some mistake and get an error message when starting LinuxCNC now telling me one infrmation is missing.
Can someone help me to get this corrected please? I am not able to find the mistake....

Thank you
Sigi
