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.

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.

Yes, I did.
After I applied the lines that DMNZ suggested, xfce started again automatically

all valid points. I have Mesa myself. I was just going through a number of threads here converting other boards like colorlight, nvem, even stm32 some of which require a lot of work and pcb mods and yet here is a board that you can get cheaper with more power, all peripherals, jtag ready, full xilinx support and no interest at all. btw this is just one of many, there are other boards from Ebang Ebits like ebaz4303, ebaz4332, ebaz4051 which are very similar.

i thought may be there is something wrong with it as i am not a fpga guru myself   I am thinking about ordering one just to learn a bit more about fpga toolchain, looks like great learning platform.

I don't think you need Litex for Zynq as it has all those modules cpu cores, ethernet, ram, rom hard wired in the chip plus fairly large fpga part to build anything else like steppers or encoders.

PS. i am actually even further down under in New Zealand   i use parcel forwarding companies from US so it is not too bad, just the shipping


 

Try this.
extract the files.
The images folder goes in  YOUR_CONFIGURATION_FOLDER/qtvcp
The qtdragon_lathe_handler.py file goes in YOUR_CONFIGURATION_FOLDER/qtvcp/screens/qtdragon_lathe/

github.com/ddjmechservices/MAZAK-VTC16B.git

We are working off of the Probe-Basic-Staging branch proofing everything out before we merge it with the main branch.

Any ideas ? No one has bothered.
Might be supported by the Litex infrastructure. The ethernet chip of that board is different to the one Mesa uses, so a driver would be at least one of the tasks.

Plenty of Spartan 6 Dev boards that are easier to use Hostmot2 (mesa fpga firmware sources) firmware with. I've had success with 7c81 setup, both SPI & SPP (parallel port) interfaces. Now experimenting with Ethernet.

Ok once you have the firmware going, the next step is designing & building the I\O, translation from 3.3v to 5v and then whatever your field voltage maybe.

At the end of the day it's just a little under what a Mesa board may cost, unless of course you're Down Under and shipping can almost double the cost of a 7i92.
