Updated sources can be found here - gitlab.com/orangecnc/ see repos with _plus names.

I made a hybrid of standard stepgen and pwmgen. New module's name is pwm. Now i'm testing it with different NC files. Works fine.

Needs some work on new encoder module. Needs some tests too.

New installer is about 80% done.

WIP: code, sleep, test, repeat, ..


Any news on H6 support?

Not supported, and H5 too. H6 needs too many work and tests to implement same functionality as for H3. Maybe in future. If you really want to see H6 in support list, become a project committer or donator :)

By the way, Orange Pi 4 and other RK3399 based SBCs (rockpi4, ..) is more featured direction to do a LinuxCNC application research. H6 has just one additional sub-core, but RK3399 has three - 2 x Cortex-M0 and 1 x Cortex-M3. Main pair of Cortex-A53 and Cortex-A72 looks interesting too. And.. RK3399 has a better graphics, more supported peripherals (full featured PCIEx4, for example).

Thanks for all your hard work.
I might be that you are making history.
Who knows maybe many people will jump from Gbrl to linuxcnc.

Rock64 also has some new boards on the way with 8GB of RAM. A port to the new Rockchip devices will likely happen later.

The Rockchip SOC's usually have the first Cortex M0 or M4 reserved for power management and the 2nd and 3rd available to the user.

Project was branched to a separate folders ordered by the SoC name - h3cnc , h5cnc, h6cnc, rockcnc. Every SoC will have own tweaks, drivers, firmware and debs. Project now hosted via github, again. But sadly.. github sponsors program isn't working for my country. Paypal and patreon isn't an options, too many issues to checkout something from. Any suggestions for donations provider?

New installer is WIP.
Encoder module is WIP too.

Made a smooth frequency acceleration. Works fine. Position following is nice. Here is an example of logic analyzer's output. Absolutely random movement. 1mm = 1000 steps. See all attached images..

If anybody wants to test updated project, you can make it right now.
Installer for the h3cnc is done. Installation is easy as before:

git clone https://github.com/h3cnc/installer
cd installer
./install.sh

Encdoer module isn't tested yet. Be careful.

Bug reports can be placed here ;)

Thanks for the hard work.

I have some questions.
Which version of Armbian should I use? The latest?

Do I have to uninstall the previous version of Linuxcnc?

Try to install `installer/linuxcnc/linuxcnc-uspace_2.8.1_armhf.deb` manually.
And you will see what's wrong with dependencies.

cd installer
sudo apt install ./linuxcnc/linuxcnc-uspace_2.8.1_armhf.deb
