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.

Hello,I would like to operate my Mesa7i76e with an external 5V power supply. Unfortunately, I cannot find any information in the documentation about whether I need to change any jumpers and, if so, which ones. Can you help?Thank you.

thank you as always for your help.
I managed to reverse the encoder scale correctly
I must have something wrong with my closed loop signal
If I jog, on the first order; my pid.x.command is stuck and don't go back to 0. don't pay attention to the enc-count, this is before the *-1 scale

 

Добрый день.
Подключил пульт, в виртуальном станке axis все работает, но реальный постоянно отваливается при попытке передвигать маховиком с ошибкой joint 0 following error при движении осью Х и остальными соответственно.
Управление клавишами при этом происходит штатно.
В чем может быть проблема?

1. Z is not connected to the joint. Check the hal file how it is done for X and Y and do the same way for Z.

2. To enable DC
refClockSyncCycles= -1000 (or any other negative or positive number you like to use, not 0)
Use the line  <dcConf assignActivate="300" sync0Cycle="*1" sync0Shift="0"/>
and remove the watchog line. Normally don't need to specify that, there is a default watchdog of 100 ms
If the drive absolutely wants a watchdog statement, use the line <watchdog divider="2498" intervals="1000"/>
 

Good work mate.

For those who like it, I've got an Armbian image ready with Linux 6.17 Cinnamon which is ready to go.
drive.google.com/drive/folders/1_WMbZC0k...ceNNI?usp=drive_link

Last core already isolated
Included sata overlay (which had to be adjusted)
LinuxCNC installed
HDMI audio works
GPU acceleration works
VPU acceleration doesn't work in the web browsers, 1080p on YouTube works fine
IRQ of ethernet automatically pinned to core 5

You rock. Thank you.

For the arc volts, from the torch-, it splits to two wires that go to 2 transformers? and then to the rectifier.
In the attached pic, I circled the torch- wire route in red and the work+ in white.
Should I just attach to one torch- wire at the rectifier or ?

Also, do you mean one 1Mohm/2w on each wire for a total of 2 resistors or two 1Mohm/2w on each wire for a total 4 resistors?
