I am running the 2.9.4nyx53 which is just linuxcnc 2.9.4 with the Yurtaev Nyx communication module for Mitsubishi Meldas drives. Just to confirm, the python break was on 2.10?

I'll check the subroutines and see if there is anything that drops the index or pulse signal.


Thanks!

Hi DJ -- nice to see you here.

Yeah, it's clear the code was wrong, for a couple of reasons. Someday I'll add proper tool-changing code, but until then I'll be more careful vetting configurations and preambles.

As for at-speed -- I'm using it because it's the only means of delaying the code during my confirmation step. It's documented as basically allowing anything to run, up to the first feed move. It's a little disconcerting watching the spindle move around and get ready before I've had a chance to hit okay. I'm surprised that there's no other positive acknowledgement signal that would delay completion of the M3 itself.

wow, nice board ! will think about it

will be happy to help you if you want to try to get RIO running on it.

Thanks a lot. This is the info I was looking for.

Rod's the one that has put them together, apart from the RT kernel & the addition of the Linuxcnc packages it's just Debian. Nothing special about the actual OS.

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
gnipsel.com/linuxcnc/debian-11-fix.html

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

NUC Intel N5105 2.00 Gz

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.

What version of linuxcnc are you running. We noticed the python broke on atc between 2.9.4 and 2.10 master.

If you're running master, check the updated python file from the latest develop version of probe basic. Run a meld file comparison to see if the latest edit is in your current python file.

Beyond that, just come through your subroutines. Check pocket counts to make sure your not dropping an index signal for some reason.

As debug everywhere to see everything is doing what you expect.
