I verifid the image download and is corrupt. Downlad a twice but result is same. You have other image?

I used the version that the video proposed. I downloaded the image that he suggested. I should download the version linuxcnc.org/2024/07/12/LinuxCNC-2.9.3/ from what I understood the version of linux cnc that is in the image would already come pre-configured and from what I understand now it is a clean version of linux cnc?

hello.

I try install but error hardware "cpu no supported" but my cpu is a raspberrypi4 b... what's going on with this?

Does anyone else have a tip as to what I'm doing wrong? I haven't found anything on the net until now. STLink with the instructions here from the thread didn't work, stlink with the hex file here from the thread flashed successfully, according to the display. NVEM v5 - Flashing not possible. I tried with DAP-link, J-Link, ST-Link v2 standard, firmware update and firmware from github. The result was the same every time, regardless of whether it was from the Raspberry Pi or with Windows 10. Either the board is fundamentally different, which I don't believe since it was recognized, or the programmers from AliExpress are all unusable.

the error messages are:
C STLink error (9): Get IDCODE error [__main__]
C Unexpected ACK value (0) returned by probe [__main__]
C Memory transfer fault (Unspecified error.) [__main__]
 

I am running LinuxCNC 2.9.3 on Raspberry Pi4. Installed using official LinuxCNC image. Its working properly.
I want to upgrade this installation to latest master branch. 
How can I upgrade to master branch? I searched a lot but didn't find any answer.

I recommend watching this video: . It might give you a good idea of what to look for.

Additionally, try finding your product information—such as the vendor ID and product ID—on the vendor’s website. It's also important to verify whether your drive supports the CIA402 standard.

Were you able to successfully read the encoder data? That could be a good starting point to ensure communication is established.

if possible share your problem in detail.

Linuxcnc works fine with Raspberry Pi 5, but when I watch it on the GUI, the positions are a bit delayed. When I use it with a PC, there is no problem. It communicates with 6 servo drivers and a PLC. It would probably be better if its speed increased a bit.

How can we overclock the Raspberry Pi 5, which currently has Debian installed on it? I want it to be faster. Are there any commands that will increase the CPU voltage and frequency? Or what can I do to make it faster? I installed a fan cooler, what else can be done?

I am using the image shared by rodw. The problem does not persist now, I have solved it. If you want, I can share pictures of how I did it tomorrow.

I am using the image shared by Rodw for Raspberry Pi 5 in the ethercat installation topic.

Are you using the supplied LinuxCNC RPi image? If so it sounds like we might need to fix something in the setup. A CNC machine shouldn't screen-blank.

There is a whole thread about screen blanking here: forums.raspberrypi.com/viewtopic.php?p=433728#p433728

(Basically there are several things that can blank the screen)

If it locks the system, requiring a password, then it won't be the always-tricksy "dpms"

What sort of step rates are you getting through the GPIO? (And which driver are you using?)

Good morning and thank you for your reply.

As you may have noticed, I am the name here. I have tried to download the image that my colleagues have posted, I have tried the Linux CNC standard and I am not able to move forward. My driver is a Lichuan LC10E. Is there any basic step-by-step guide to help me achieve my goal? Thank you very much in advance!

At a guess, the image you have used is 32 bit and the Pi4b is 64 bit
Please use the image on the linuxcnc downloads page and not the comments arouns seting wifi etc.
