Yay that's awesome. I'll log on and drive in in a few hours (my DC user/pwd is on another PC). Prolly a better hangout to share vendor-neutral dev and goodies I'll catch you there boyz.  

there is one, ok, i will try

That is so cool. ok 7i90HD x10 here we come!!

Discord channel guys? linuxcnc geekheads hangout you heard of one?? I swear I read cakeslob mentioning about one in another thread, the remora thread if I'm not mistaken.

Is it possible that you have information on when Mesa Cards will be available, I mean 7i76EU for example?

Ya won't believe this, just found a decade old spartan-6 sitting in the bottom of my abandoned gizmo box. Let me dwload the toolchain for that badboy and I'll give it a trial tomorrow after work. If this all works out as planned I'll get two of those 7I90HD. Haha Magic, Effortless!! 

 

Yeah I've already done that. Great care is required in selecting the pins for the SPI port, selecting just any pins wont give you a successful bit stream.
The way  I designed my boards was to run the Mesa 7i90HD & 7C81 firmware & a custom firmware with it's own board name. The daughter boards support both EPP & SPI interfaces, the way the ports were designed were to allow use with genuine Mesa daughter boards, even being able to supply 5v to the daughter boards via a jumper. I tested my setup with the Mesa firmware with a 7i73 smart serial pendant board and used a heavily modified 7i90hd smart serial firmware to run on a RV901T colorlight board, but will run on any Spartan 6 dev board, yes the 7i90 can be used as a Smart serial board as well, Mesa have firmware configs for this.
The boards now also run the rio firmware and there is basic board config on Ollie's github repo. I suggested a while ago that the 7i90HD would be a good candidate for this project, what makes this a good candidate as well is the dual SPI EEPROMs.
In all honesty running the rio firmware on these boards removes one of the great functions of the Mesa infrastructure, the Smart serial interface.

So yeah having all the info on these 2 boards it wouldn't take long to whip up a board config for them. Just a few slight mods to my own Spartan6 config.

Von 7i96S.
Kein externes strom, das macht probleme mit potential und interference.
Das sind nur 4 drahte fur die THCAD von Mesa 7i96S, dan 2 fur torch on und 2 mehr wen die ARCOK von plasma nutzt.
Ein gute CAT5 oder CAT6 LAN cable mit schirm (shielded) ist OK.

That's awesome. Farewell Gowin Let's go Spartan!! I'll update...

@meister, is there a discord channel/server where linuxcnc users and devs exchange ideas and what not? Read someone here saying discord a few days ago but unaware of one. I'd love an invite to this venue if you or anyone knows of such platform. 

@cornholio have a spartan6 board running on rio

the mesa boards have no network and are nothing more than a spartan6 with level shifters, you also need BOB's to be able to do anything with them

i thought you would have fun building boards, we have ready-made designs, nothing great but they work

github.com/multigcs/LinuxCNC-RIO/tree/main/configs/Tangoboard
github.com/multigcs/rio-octobot
github.com/multigcs/rio-iceshield

Eine kleine Frage….
wenn es nötig werden sollte eine THC Carte zu verwenden würde ich die gerne im Plasmagerät einbauen…
Muss die Spannung von der 7i96s kommen oder kann ich für die Versorgung der THC Carte ein Externes nehmen ?
Wenn der Encoder Eingang potenzial frei ist ja aber ist der das ?

Goes to show how much I need to learn, this option honestly slipped my radar. Awesome, seriously. You need me to put 2 (two) on order? happy to drop-ship one over DE for you to thinker with.

Screw that pricey gowin board, common sense lool Not all wasted though, no worries, good ref design for other projects!!

edit: boy oh boy, you said spartan6... that means the old buggy IDE/ISE ver 14 something something, forgot. Uh oh.. alarm

[qoute] To test the scurve motion planner in linuxcnc i added a new repository , based on lcnc stable version 2.9.3.
Inside the repository we have the cmake framework to build one the current motion planner "tpmod" and
two a motion planner called "tpmod_scurve".[/quote]

So having cloned your repository, is there a way for me to compile 'tpmod_scurve'?

no no no, you should finish building your board,
forget the mesa cards again very quickly

I just want to support as many boards as possible and these 2 mesa boards have no network, so it will be easy to support them. especially since the Spartan6 are already supported anyway.

If anyone has the boards, I'm happy to help remotely create the configs for them.

Oh man, why you didn't flag this up before today. Certainly not going to get the 7C81 (raspi thing) but will press on getting a 7I90HD right away. Geez, excellent timing none the less, saves me from assembling >$200 worth of parts on some pcb I don't even know works lool
