  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.
