Do you happen to have LinuxCNC-RIO ported for the Gowin IDE? I'd like to explore your awesome work however would be willing to do so in an environment that I'm semi-familiar with already (i.e. Gowin IDE).

Thanks, yes gowin toolchain is supported, it even generates a project file for the IDE.
However, it is easier (at least for me) to work without an IDE, so you are not so tied to one manufacturer.
Since everything is more or less generated here, an IDE is only suitable for troubleshooting and playing around

for new projects, the best branch is here: 
github.com/multigcs/riocore/tree/dev

littlebee is not yet directly supported, but if there is a GW1N-9 on it, it should be no problem to use the TangNano9k configs as a template

copy the file: riocore/boards/TangNano9K.json to riocore/boards/LittleBee.json and edit it (type/family/clock-pin/speed), set toolchain to gowin

than copy riocore/configs/TangNano9K/config-uart.json to riocore/configs/LittleBee/config-uart.json and edit it (boardcfg and the pins / you can also remove all plugins and leave only the uart and blink for first tests)

then you can generate the Gateware with:
clear ; PYTHONPATH=. bin/rio-generator riocore/configs/LittleBee/config-uart.json

if all works, you will find a project file for gowin-ide here: Output/LittleBee/Gateware/rio.gprj







 

Pretty sure something like that can be done with LinuxCNC, as almost all motions are unique and repeat all the time, so each station has a single motion to do.
Probably most can be done with separate stepgens or siggens and some hal fiddling to ensure the tools are in place before moving the main part holder.
Add a VCP for editing values tools have to move and....

This is from back when i started using LinuxCNC and thinking what can be controlled by it, so just stuff in my head as i never had a chance to try and build such a machine.

Ah, I see.
I'm afraid not. LinuxCNC is not multi-channel capable so it cannot synchronize axes moving along different tool paths at the same time.

[edit]
The only way this could work would be to use a different installation of LinuxCNC for each station and synchronize the program execution using digital IO

Hi
waiting for a more suitable solution

I solved it almost like zylos146.

I searched and deleted all the ethercat-dkms folders, including the .deb

then I downloaded ethercat-stable-1.6 from
gitlab.com/etherlab.org/ethercat
followed the installation from install.md everything went well.

then I performed the standard installation here
it no longer returns errors
Hi

Just get some cheap TB6600 drives, wire those directly to an old PC with parallel port, make the machine move.
No AI will help you with that, yet.

@spumco Wow the white looks so clean, got me a bit jealous haha. I'll try to keep all servos original, they probably have a better quality than some chinese servos, even though 30 years have passed.

@PCW Thank you, then it's a no brainer. Will start with the 7I97T and continue when the 7I84 is in stock.

By Rotary transfer I mean a milling machine with a rotary table with multiple stations, each station is like higly customized lathe, it holds a working piece and has multiple Units that perform a specific work on the piece.
Each Unit is composed by multiple axis depending on the complexity of the work, for certain a spindle and at least the z axis, but could even have x y z axis.

Something like this:
 

I also foud this to help define it: en.wikipedia.org/wiki/Rotary_transfer_machine

Thankyou all

 

Do you mean something like this:

 

[edit]
If so, that is not really an application I would choose LinuxCNC for but as a proof of concept why not. Although I would probably much prefer to use a PLC.

 

It started to be an issue mainly on very fast routers and plasma cutters, and when CAM started to be more readily available (and, to an extent, when it started being used by novice CNC-ers who assume that the smallest possible path length mush be highest resolution and therefore the best.

Exactly.
Here is a good example of how simply changing the CAM settings may fix slow Gcode execution despite the one line lookahead:

Hello,
I am new here and overall in the CNC world.

I just wondered if LinuxCNC is suitable for Multi-Station like Rotary and Linear Transfer Machines, that have many Units and Axis, at least many more than what I have seen in the examples.

And if not what would take to make it so?

Thanks in advance,
G.Pasotti

well... thanks for your help

I'm sorry but it's just like last time you asked for advice here:
forum.linuxcnc.org/27-driver-boards/5109...17x0?start=10#288989

You turn up with some hallucination and expect other people to make it come true for you.

Wow aciera youre right again. I cant believe that was the issue. But if anyone is seeing this in the future turn up your smoothing and tolerence in fusion 360.

My line segments are about 1 to .5 thou now (they were down at about a 10th before) and i can get up to somewhere about 60-80 percent of my feedrate which is way faster. Theres work to be done if I needed to cut a bunch of aluminum but this is a test cut for inconel, so this speed will work just fine!

Thank you sir!

I tried to reinstall everything from scratch, to no avail, the keys are not updated. I think we should intervene on the image
