Hello,
I am new to LinuxCNC. I am trying to get a Festo CMMT-AS-C2-3A-EC-S1 to work via Ethercat with the CiA402. Unfortunately, I keep getting error messages when I start it up and have no idea what the problem could be.

Error message when starting up.

I have attached my hal, ini, and xml files below. Does anyone have any idea what I have configured incorrectly?

Thank you.

Hey guys
I have similar problem.
When hitting page up or page down button, the z axis starts moving until the end stops. And only stops moving if probe sensor is touched or esc button. 
Why does the probe screen behaves that way? 
is it possible to remove this function? 

I started to read the different py files, but didn't find a clue to this problem.

So I don't have to worry about the pins not being created?

No. Hal connections are created on startup when the hal files are read. If a hal pin used in any of your hal files was missing the config would not start at all. So your problem is not because of 'signals not being connected correctly'.
One thing to do is start your config from the terminal and check the output in the terminal. Another is to check the XHC WHB04B hal component using the halshow tool to confirm button press events are actually reaching your hal connections.

Thank you for your quick response! I didn't think about it that way... So I don't have to worry about the pins not being created?
What could be the reason for some of the signals not being connected correctly? I mean, it was working on 2.9.4 after all. I managed to solve a lot of problems while setting up my machine, most of them thanks to posts on this forum. This issue i can not wrap my head around.
But I will do what you suggest and check the signals.

I did some research and it looks like something is wrong with installation. I have no problem of reinstalling it from scratch, if it makes sense.

If your config would need any of those pins it would not start up at all but fail with an error about a missing hal pin. The first place to troubleshoot your issue is to open the halshow tool and check the signals coming from the pendant.

Hey guys,
my config works as i want it on linuxcnc 2.9.4. After updating to 2.9.5 (or 2.9.6) it does not anymore. It mainly is the pendant that is not working as before. I use a china pendant (XHC WHB04B). Most buttons don't work anymore. For example when staring my machine, I hit the "reset" button. With version 2.9.4 I can home my machine after that. With 2.9.6 nothing happens. Control via GUI seems to work just fine.
I think the problem must be related to one of these, or maybe both points in the changelog:

• halui: on startup, set the first configured axis as ‘is-selected’ instead of X
• halui: Don’t create ‘halui.axis.’- pins for unconfigured axes

I looked at all created HAL pins under 2.9.4 and 2.9.6. I compared the output and found some missing pins under 2.9.6. I don't see why i would need these pins, but I figured it maybe where my error is? See the atteched pic for the missing pins.
I hope someone of the pros on this forum can help me. I don't know how to solve this on my own.
 

I've got this replay and I don't understand what is going on.

Hi Tommy,
I did it, and there was no Lan card reported. Even, if I tried to add new connection, didn't work.

  With the RPI4 being a viable contender albeit marginal for linuxcnc I thought I'd share some results i got from a stock RPI5 with a SD and with the addition of a nvme hat. I think they have knocked it out of the park with this one.The first one is with a nvme ssd hat added and the second one is with the standard SD card.  

Hello,

Sometimes try to tinker something that roughly corresponds to functionality, which I am looking for for Qtdragon.
I have little idea what I copied together. But it only runs in studio code how to explain the Linuxcnc, so I am light years away to understand it.
Here is the code snippet:

import cv2

cap = cv2.VideoCapture(0)
cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1600)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 1200)

while True:
ret_val, img = cap.read()
down_width = 800
down_height = 600
down_points = (down_width, down_height)
img = cv2.resize(img, down_points, interpolation= cv2.INTER_AREA)
cv2.imshow('my webcam', img)

if cv2.waitKey(1) == 27:
break # esc to quit
cap.release()
cv2.destroyAllWindows()

Best regards and have a nice weekend, Frank.
Translation errors come from Google.

Maybe it is in the homing file? Perhaps I can change the homing file to rehome rather than return to home if that it is indeed the case that it is not actually rehoming?

Ok, thanks

No jumpers need to be changed, and you and run the logic side of the 7I76E on 5V, but
since the field I/O side needs 12/24V, there usually is not much point.
