LinuxCNC + Orange Pi (allwincnc)

After Installing linuxcnc-uspace_2.8.1_armhf.deb manually the installation finished with only one error message.

Question am I supposed to login as root before installing Linuxcnc? Or is there another reason for this error message?

I have now two Linuxcnc shortcuts on the desktop and can open both of them.

Install using non privileged user with sudo. Don't use root.

Found this error's reason inside install_linuxcnc.sh. Already fixed.
Update the installer and install emc again

I can confirm that the latest version builds, installs and runs on an OrangePi One with 512MB of RAM. I would not choose this board for anything other than testing. Running a browser takes up all the memory and often stalls or crashes.

Armbian does NOT use the GPU hardware accel drivers for the Mali400. I tested and installed the latest Buster Armbian_21.02.3_Orangepione_buster_current_5.10.21_xfce_desktop.img.xz
www.armbian.com/orange-pi-one/#kernels-archive-all
It uses LLVM pipe software rendering.
We need to build a version that uses the Panfrost drivers.

Mali-400 (lima/mesa) isn't a big option to make desktop OpenGL apps works fast. Mali-400's performance is too small and it supports only OpenGL ES.

Mali-T720's (H6 SoC) performance is much better. Already tested with Panfrost. But Mali-T720 supports only OpenGL ES, as H3.

I also had to turn the Compositing OFF in the desktop settings to speed up desktop movement. Again, I'm using the 512MB Opi One here with H3. Core clock governor at 1200 MHz min and max.

Hello all
I just installed armbian buster xfce to an OrangePiPluse2e
the got the repo for orangecnc and ran the install script
no problems
it just worked.
then i checked the ini and hal for 3A_test and saw it was safe to run ( no limit switches no estop switch , just xyz step/dir and pwm for a spindle)
I saw it used arisc_pwm for the stepgens and knew it wouyld be using the arisc side of the Opi_2e ( great )
It runs well,

I have AXIS running fullscreen and can pan zoom and rotate quickly while running 3Dchips( tool change removed temporarily , not handled in hal )
I got NO unexpected realtime delays UNTIL i browsed intenet while running AXIS.
I can simply _not_do_that_

thanks MXMaster
send me a pm if you have a way to get you some scratch.

I'm very interested to give this a try, but what Orange pi should I get, the Plus 2E is 200usd I may as well buy an RPI and mesa, the Orange Pi PC has a H3 with 1g ram for 30 USD will this run it ok, can I use the onboard HDMI or will that slow it down? Thanks for the insite

Use HDMI or remote desktop - it's your personal choice

When I get a 1GB or more H3 board I'll try to see what we can do about running the browser. The Armbian RT kernel is a dog and Uboot needs to be properly configured to not speed step while running real time threads. This all looks workable.
