LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC

Hi I have make two linuxcnc on raspberry pi 5 both on a HAT from bot 2 byte page byte2bot.com/products/parallel-port-raspberry-pi-hat and the mill setup is working fine and the other is a lathe setup , the lathe setup is working but I dont understand why I cant get the spindle indexing work in labour ,i dont understand the behavior of that part in the Hal file and why it dont show upp in the Hal test window as working

Hi means an output for RC-Servos

Yes, exactly, a three wire RC servo to control the gripper.  I overlooked how to control this pseudo axis.

Category: Installing LinuxCNC

Good day.  Installed tigervnc-standalone-server on title iso.  Lots of examples of how to install it, tried all, none worked.  Big issue here is the vncserver will not start.  Unsure if this is due to the windowing system or what.  Could get the server to start against /usr/bin/xfce-terminal, but viewer couldn't connect to it.

Has anyone gotten any remote-control software to work on this Debian Bookworm (aarch64) release?

Edit1: after booting the system today, the display goes black right when the logon prompt would appear.  Can SSH into it, and lo and behold, tigervncserver just worked!  Could remotely view it just fine.  However, no local display.  So reloading the .iso and trying again.

Edit 2: after retry, can confirm that vncserver will work, but only for root.  Here is as far as I've gotten:
sudo apt update  # note, have NOT updated any packages yet!
sudo apt install ssh tigervnc-standalone-server
vncpasswd  # this is for the cnc account only
sudo vncpasswd  # apparently this will allow root to login as well
vncserver -localhost no  # does not work, our cnc user
sudo vncserver -localhost no  # no error, but note this is root!
# try remotely connecting to the machine's IPaddress:5901

This was the bare minimum to get any sort of VNC connection to stay running.  Of course, not done yet, as the client window displays a big, fat Unable to contact settings server. Failed to execute child process "dbus-launch" (No such file or directory.)

Checking, package dbus-user-session is installed, but not dbus-x11.  Installed the latter, tried VNC again, and BAM, works!  Except that the root account is served.  Attempting (non-root) vncserver -localhost no gives the following:
cnc@raspberrypi:~$ vncserver -localhost no

New Xtigervnc server 'raspberrypi:1 (cnc)' on port 5901 for display :1.
Use xtigervncviewer -SecurityTypes VncAuth,TLSVnc -passwd /tmp/tigervnc.xtgF1d/passwd raspberrypi:1 to connect to the VNC server.

Maybe try something simple first, e.g.,

Any ideas why the sudoed command would work, while the non-sudoed does not?

...For my final design, I will add a 4,700 or 10,000 uF/ 6.3 V (or 10V or 16V) electrolytic across the 5 V rail (close to the Pi power input) because I have noticed that plugging in the Mesa card causes the Pi to reboot. The Pi evidently has very little on board power supply capacitance.
 

Just be careful not to exceed any "maximum load capacitance" of the supply.  All switching supplies will oscillate (or worse) if loaded with too much capacitance.  Sometimes this limit is mentioned in their datasheet, sometimes not.  If you can access an oscilloscope, 'scope the power to ensure there isn't any ringing or other oddness happening (this can be in the MHz range, completely invisible to multimeters.)

RPi4 can do ethernet, gpio & SPI

RPI5 can do ethernet, maybe able to do gpio can't do SPI (no idea if or when that will happen)

You would have to check availability of 7i90, 7c80 & 7c81 for RPI4 Spi at Mesa.

I've been experimenting with some FPGA dev boards I've bought from Aliexpress that run 7c81 firmware, & a customised firmware.

Here's an example of what I've done.
forum.linuxcnc.org/show-your-stuff/51142...pga-card-9d60#289226

There's also a couple of projects such as:
github.com/multigcs/LinuxCNC-RIO SPI or Ethernet
github.com/sensille/litehm2

I don't know if the Remora project has the IO you need.

Bit of a warning tho, litehm2 requires some modding of the board.
LinuxcncRIO requires the building of external board to get 3.3v to 5v translation.
My own project requires that as well, but has been designed to work with standard parallel port Bob and mesa DB25 daughter boards & smart serial, tho does require a RS-422 board, cheap as chips from Aliexpress.
At the end of the day the "roll your own boards" can get close to the cost of a genuine Mesa board.
If the 7i90 were available I'd go that way, about the cheapest Mesa board you can get & has 72 IO only "issue" is that the IO connector is not DB25 compatible but I think there is an adapter available, 7c81 would be next as it makes a compact unit with the RPi4, but requires a breakout board between it and you hardware.

At the end of the day it really pays to work out the cost of the board itself & any any items needed to connect to your electronics, sometimes what does look expensive turns out to be cheaper in the long run.

I'm running a 7i96e Mesa card on my CNC router and am very happy with it.  But I'm thing it is over kill and lacks a channel.

For a hobby/educational project I need 5 stepper channels and a servo channel.  I was thinking of using a Raspberry Pi 4 or 5.

What would be the cheapest option for a LinucCNC compatible card driven off a Pi?  What are the options today?

After going through this thread, it seems that the current RPI5 image on the download page should be sufficient to get a usable RPI5 OS install.

I have been working to install the image on a new RPI5 with a Pimoroni NVME installed. I've tried installing on both the SSD and the SD Card. In both instances I end up with no network connection (neither Wi-Fi nor Ethernet) and no network configuration utility under settings.

What additional steps I need to take?

Thanks,

Is SPI working at proper speed on Orange Pi 5 for real time use? (Raspberry Pi 5 SPI currently has issues with slow speeds / access making it not suitable for real time functions I believe)

Remora for RP2040

Category: Computers and Hardware

Good idea to wipe the whole chip, didnt know that was needed or possible for the RP2040.

Oh my god, it actually worked!
I used the flash_nuke.uf2 file from electrocredible.com/how-to-reset-raspberry-pi-pico-w/. At first I unplugged the pico after dropping the file on the pico directory and it makes the disconnecting sound from the computer, DON'T DO THIS. It seems like it takes quite a few seconds to wipe the whole memory of the pico and once it's done it returns to bootloader mode and shows up as a directory again.

After that I dropped the remora.uf2 on there and got a nice blinking LED and everything, error in linuxCNC is also gone, I'll check if everything else works aswell tomorrow. Really glad I got passed this though.

Thanks!

Hi, thanks of the manual of Cold Turkey i was able to flash the board, but without success :-(
I erased the board with
(pyocd) cnc@raspberrypi:~/linuxcnc/Remora-RT1052-cpp-main/Firmware$ pyocd erase --chip --target mimxrt1050_quadspi
0000867 I Erasing chip... [eraser]

i got the same error as vpomerlo on page 166. I tried to ping the board -> no reaction, so somthing was done.
Next step was to flash the firmware with pyocd and a STLink V2 adapter. This worked well:
(pyocd) cnc@raspberrypi:~/linuxcnc/Remora-RT1052-cpp-main/Firmware$ pyocd flash remora-rt1052-3.1.2.bin --target mimxrt1050_quadspi

OK, now i was able to ping the board on 10.10.10.10

(tftpy) cnc@raspberrypi:~/linuxcnc/configs/remora-rt1052-basic$
as a result all outputs are off and the "CONN" LED is now on.
Next step: i connected the serial interface, because on my old NVEM i was able to see some reactions on RS232. I directly connected a RS232 to USB vonverter to the board and looked with cutecom on the interface (115200;8;n;1) but i see no response? Is this normal?

after logging in, when starting linuxcnc basically saying
...
_tkinter.TclError: no display name and no $DISPLAY environment variable
Shutting down and cleaning up LinuxCNC...
--
I tried an older version:linuxcnc-2.8.2-buster.iso
and got that working, so something must have changed since that and the linuxcnc-2.9.1-bookworm-rpi4.img.xz (and later) versions

Thanks
