Good evening all

I was really holding off on asking for help as i much prefer to figure things out for myself but i'm running up against a few specific struggles and i'm starting to get the feeling that i'm just missing something that perhaps you experienced folk may know about due to experience. 

I have setup a nice pc with Linux Mint 22.1 using the ISO Tommylight provides. the LinuxCNC included in this was 2.1 which seems old and this is however the first detail i might be missing the mark on, in hindsight 2.1 seems to old to be logical so perhaps its a different variant? Regardless, i uninstalled that and installed 2.9.4 which went without a hitch, but did not make anything work any better. 

I then came across MesaCT as pnfconf doesnt support this card. I set the card jumpers as per instructions in MesaCT and i can ping it on 10.10.10.10 but i cannot connect to it.

MesaCT reports that the LinuxCNC version is "version error" - my gut feeling is that the linuxcnc version is newer than the latest update for mesaCT and its just not able to report on it correctly - can anyone confirm if this is preventing operation?

Finally, the detail that i believe is actually stopping MesaCT connecting to the 7i97T - the mesaflash version is reporting (correctly) as 3.4.6, MesaCT notes that for the 7i97T connect, Mesaflash 3.5.3 is required, however i cannot for the life of me find where this is to be obtained, or even any reference to a mesaflash above 3.4.6 other than a few posts on this forum where users mention they are setup with 3.5.x and don't seem to suggest that this was at all difficult. Those posts were all a couple of years ago, has something changed with the version numbering? 

I am not at all new to computers but i dont have a large amount of experience with linux, happy to do the learning but it looks like i need a swift kick in the correct direction! 

Any help greatly appreciated

p.s. i couldnt decide if this should go under "installing" or "general" apologies if i picked wrong. 

Hello Aciera, thanks for the reply.

I haven't had anything to do with the kinematics module yet. I'll stick with the experiment in the HAL for now.
(but ​​that will definitely happen sometime...)

I've been experimenting a bit with "moveoff-external." With a fixed offset value, it looks quite promising.

Now it's about creating a variable from the B-axis value to put it into mv.offset-in-4 (C-axis).

For the calculation, I'll use mult2 with a fixed constant of 1/51

mv.offset-in-4 = mv.pos-3 * (1/51)

I've looked at some values ​​in the HAL show and I'm not quite sure which would be the best:
bpos-cmd, bpos-rel, or mv.pos-3.

I'll play around a bit more.

Best regards,
Kai
 

If standard Modbus works one can wonder why there is a hal componenet for this vfd?
The old Huanyang vfds use something similar to but not quite Modbus so there it is needed.
 

Yeah I'd take what that user says with a grain of salt, unfortunately he can be a little unreliable or completely off the mark.

Try this command to see what is installed

Confirmed is a SW issue.

I replaced the hy_gt_vfd driver with mb2hal, which is a generic modbus HAL component, no HW changes, and it works.

nice....thanks

For configurations with specific daughtercards, the daughtercard 
name is included in the file name and you can use the .pin file
to determine the content and pinout of the firmware, for example
the 7i76eu_7i76x1_pktv2d.pin file shows that the configuration
includes a V2 PktUART ( the TX and RX halves )

Thx.
Just out of curiosity…
Is there an overview what all those firmwares do / are meant for?

Or how could I have found that out myself?

Regards

7i76eu_7i76x1_pktv2d.bin 

Would be the correct firmware

You will also need to update LinuxCNC to the lastest version
sine the hm2_modbus driver is quite new.

 

this post says that vnc is preinstalled.

forum.linuxcnc.org/38-general-linuxcnc-q...time?start=30#328405

however - thx for your feedback, I will just manually install one.

thank you.
I know I need to update / flash my 7i76eu.
The "bundle" from your webpage contains 20+ different firmware files... I would assume that 7i76eud.bin/pin are the correct ones, right? (for a standalone 7i76eu without any extensions)

This should work for 2.8 and up, notice the hal command at the end for refreshing the Gremlin (plotter).

Thanks. With you and juliankoenig and the links, I have plenty to work with.
I really appreciate you guys taking time to reply and share your knowledge.

Not really what I wanted, but I think it will work.
Thanks for the link to the example code.
Thanks for your help.

I recall there was chat about including it, i was against it as it is a huge security risk and not required for machine control.
-
If it is included, it does require setting up the password for VNC explicitly, at least it did 10 or more years back.
