I'm using LinuxCNC 2.9.1 on a Raspberry Pi 400 with Debian 12 "Bookworm" (just for benchmarking, will upgrade to desktop when I get everything installed on a real machine) and connected to a Mesa 7i96s.

The 7i96 is connected to a DM542t, which is then connected to a Nema 23 stepper motor () that is set up for the X axis. I installed everything and ran the Mesa config tool and it shows a connection to the 7i96s.

When I turned everything on I was driving the stepper motor and knew this because it was frozen and I couldn't turn it.

The connection between the 7i96s and the driver is as follows:

Step 0--->Drag-

Step 0+ -> Pool+

Directory-->Directory-

Catalog+ -> Catalog+

I don't know where to start troubleshooting, any information would be helpful.

I could not use Eagle so I have remodeled Oliver's OCB in KiCad.
I use different connectors. Noved the 5 outputs to the oppesire sides and have 5V/24V selection on all inputs (also wih option to change resisor values). Also added some capacitors.
If I make a new version I would use 6 pin JST to get 5V from the Raspberry PI. Possibly add MAX485+protection circuit to the board.
If there is demand I can put the Kicad files on github.

I am switching LinuxCNC from an old PC to RaspberryPI + Tango compatible board.
I see that riocore has support for HY_VFD and I want to use it. After resolving simple issues I can get a serial signal out of the Tang Nano, but no connectio to the VFD yet. I guess I will need a TTL to RS485 brekout board. Will this one do?

Last time that I made changes to the HY_VFD configuration it cost me a burnt spindle, so now I'm trying to learn more and if possible from other's experience. I will appreciare any help and suggestions.
Thanks!

Is your vesion of the Tango board a modified PCB? and is there Kicad or PCB repository.  Just so I can compare the difference with Olivers version.
Many thanks

Good morning, I'm confused!

I'm actually making a scara but I couldn't change the home screen, etc. I'm using a theme from a router... and I want to change it to a scara. Can you help me?

Hello bertoldo,
I have no experience with Raspberry Pi. I do with Laptop + Debian 12 RT kernel + LinuxCNC
Here is my files for SCARA with Gmoccapy demo.
You just need to revise EtherCAT "xml" file to meet your real motor servo controller.
Hope you find it helpful.
Tks.
 
 
 

Was going to open a new thread, but thought the image authors might want to get some feedback that might relate to the image.

Installed the 2.9.3 image on a RPi5 and after a few self-inflicted hiccups everything seems OK, including qtpyvcp/probe basic.

Except the touchscreen isn't reconized.  lsusb does't show the touchscreen.

I've got the touchscreen connected through a powered external USB hub, and I've tried every other combination of ports.  The RPi5 seems really picky about what hardware works (or doesn't) on various ports.

Keyboard w/touchpad is fine, as is a usb trackball.  Both of those work through the hub and directly in one of the Pi's ports.

Any ideas on what to do about the touchscreen?  Monitor is one of those generic 15.6 things, and works fine on everything else it's plugged in to.

Thank you very much for this work. I have tried X times to compile kernels without ever succeeding.

thanks again for your work

With this image I was finally able to get ethercat working, with the image for Pi4 that is on the LINUXCNC page it was never possible.

It looks like the release manager has not released the  2.9.3 Image I gave them. Try this one
