Here's some of the stuff I've been working on. Should be able to add an ethernet interface to replace the SPI\EPP board.

The same hardware can be used with Linuxcnc-RIO.

Omdazz board is currently about $45 AUD.

There are some cheaper ones around.

Nothing to do with menu-config. Its all Linux

would definitely use encoder if you want to change the values from different places

i think arduino-connector can do that.

or the luxury version

I want to add 4 override pots-encoders to linuxcnc.
Feed-rapid-spindle-jog override because qtdragon sliders from touch screen are not easy usable.
How can I do it this.
Arduino and potentiometers? Other way?

Hello,

Forgive me, but I am a bit new here. I have been trying to setup an RPi 4 with an Octopus 1.1 (STM32F446) and I am hitting a bit of a brick wall with trying to get a hello world going with a setup of just 3 stepper motors on a bench.

Can you please point me to a good tutorial for help please, both for understanding the basics of LinuxCNC and then how to get Remora up and running for this setup? I have installed the Flexi-Pi RPi image, that is up and running. I have flashed the Remora firmware to the STM32 using the ST CubeProgrammer utility. I have loaded the example configto LinuxCNC and I can "open" it. But then a whole lot is blanked out and I can't seem to get any response from it. I have a feeling that I missing the step where I load components and I am not sure how to do this.

Any input would be greatly appreciated.

Thanks,

Dylan

I'm not an expert at this, but I've seen some of things you noted, and here's my take on them:
I think it makes sense that a tool change would want the spindle to stop.  I mean, unless your system can change a tool at 24,000 RPM.  My custom ATC code halts the spindle too, and waits for it to stop.  So, after M6 (tool change) you should always M3/M4 if you want that tool to turn.  To be paranoid, you should M5 before M6 too, as needed.  Remember that M6 is the tool change; the T command tells the changer which tool to prepare.
As for the at-speed signal, beware - if there's a delay in setting it, the system might not wait when it should.  I used an at-speed signal with a VFD and it didn't respond fast enough, I ended up reading the VFD's RPM and comparing that to what motion wanted.  At least a delayed "0" is still not the same as the desired 24,000.
I think it's normal for the system to allow rapid moves before the spindle comes up to speed, because rapid moves aren't intended for actual cutting.  It's only when the first G1/G2/G3/etc is seen that it knows the spindle must be ready.

Hallo,

ja, hier laufen ein AX5106 und ein AX5203.
