7I96S firmware with P1 pinout for the common "Mach 5 Axis BOB"
2 additional step/dir channels (7 total) and 4 RCPWMgens on the BOB

So correct me if I'm wrong.  The firmware sets up the bob as an extension of the 7i96?  So with MesaTool2 or Pconf what type of bob do I define P1 as? 

Is there a tutorial somewhere showing how to incorporate a Mach3/5 bob with a Mesa card? 

Try elovalvo';s images. I find they usually work pretty well.

Dear Experts,

I followed the relevant discussions about installing LInuxCNC on RPi5 but I haven't been able to find the information about LinuxCNC running on it  :

forum.linuxcnc.org/9-installing-linuxcnc...nc-on-raspberry-pi-5
forum.linuxcnc.org/9-installing-linuxcnc...4-and-raspberry-pi-5

It will be really appreciated if someone could share his/her experience/observation about the performance of such configuration compared to its predecessor, RPi4, please ?

Best regards,
Khang

Tried many things.
1. Recommended flexihal image. Can't update, errors while updating. Most of the GUI gave errors. Only axis you were testing was working, that too after commenting out user_command in ini file.
2. Official raspberry pi os12 with LinuxCNC 9.2
Every gui worked. But too much latency.
3. Tried official LinuxCNC 9.2 image for rpi4. Works good. But no raspi-config or vnc. Not able to activate ssh. Only able to work on connected display and key/mouse.

hello guys
i am trying to install ethercat configurations for linuxcnc
i am using raspberry pi 4 with : 1 ) kernal : Linux raspberrypi 6.1.54-rt15 #1 SMP PREEMPT_RT Fri Nov 17 17:02:27 AEST 2023 aarch64 GNU/Linux

i am using this link to install ethercat: gist.github.com/Bouni/8b4532d0bdf012bd83c65d3eb62f8aa2
i get error when i finish installing and run command "ethercat master" , the error is :
cnc@raspberrypi:~$ ethercat master
Failed to obtain number of masters: Failed to open master device /dev/EtherCAT0: No such file or directory

 

Hi,does anyone know how to change the official raspberrypi 5 linuxcnc image 's screen resolution and color depth ? it looks that the dispaly just not drive correctly after installing, I dont know how to solve it .

Higher speeds for what?
Mini industrial PC's are very slow in every way, the cheap china ones are a bit better and faster, strangely.
In general, no you do not get higher speeds for anything with industrial PC.
Buy a normal PC, or a used Enterprise Edition Optiplex or HP 800 or Fujitsu.

I was wondering if I used a mini industrial PC, will I get higher speeds

I'm afraid not ,I didn't find remote assistance in linuxcnc Raspberry Pi 5 image.Does the error showing up indicate my connection of the hardware wrong ? I just use my Raspberry Pi 5 connect the leashine L7 servo and step moter 556 ,I didnt use Beckhoff Bus ,is this the possible reason ?

by the way ,when I run ethercat slaves ,it showes
cnc@raspberrypi:/$ ethercat slaves
0 0:0 PREOP + L7EC-750(COE)
1 0:1 PREOP + DM3E-556(COE)

I supposed the etherCAT has connected ,so I dont know how to do next because I met the error msgs above

Thanks a lot.I've just installed etherCAT in my raspberry pi 5 ,and I dont know what to do next .I 'm just new to EtherCAT .and I dont know how to control the machine through servo and step.it looks there is no GUI wizard in linuxcnc. Can I run your xml and hal code in my raspberry pi 5? is it used for controlling and testing machine just like the linuxcnc wizard do ?

Thanks, I've decided to use EtherCAT,though I'm a newbee to this .I've just installed the EtherCAT by following the instructions in the forum to my RaspBerry PI 5 and I dont know what to do next ,To me ,the wizard is just GUI interface and friendly to the newbee ,but our company's boss decide to use EtherCAT ,so I've to dive to it. I dont know how to control the machine after I installed the linuxcnc-ethernet .after all ,there is no wizard in linuxcnc supporting etherCAT
