What does mesaflash --readhmid report when  the 7i80db_16_7i85sx3d.bit firmware is loaded?

That all sounds correct. I think I misunderstood your problem with Z position. Can you provide more details?

PUMA 200 Robotarm and some Hal/INI issues

Category: Advanced Configuration

Yes.. power up.. start linuxcnc... loose the brakes.. bring all joints to the sharpie marked position. Then reference/home to the index of every single encoder.
After this all joints at zero. B axis has offset 1 degree that there no failure message comes from linuxcnc because.. if all joints at 0 degree they are in singluarity... thats why its needed to brin as example a small offset to the B axis.

Thats how i understand it.

I had a 7i80 with a 7i85s and a 7i37 working with 3 stepgen, I tried reconnecting it and only a step dir signal comes out of the y-axis and that's it. I loaded the firmware 7i80db_16_7i85sx3d.bit. I don't understand what could have happened, I put it away and all three axes worked.

I only had zero x y z in genser mode... not correct?!

 

First at powerup you have to zero every joint, did you do this?

disclaimer:
I have not yet had opportunity to run a LinuxCNC robot, except for playing with the sim. I have spent many hours programming/repairing Fanuc and ABB robots. Some day when I have enough projects completed to make more space in my shop I want to buy an old robot and put LinuxCNC on it.

I know that when i rotate A axis the B axis make moves.. because the mechanical stuff inside the hand goes over small gears.. but this should not be the problem or???

Thanks

I have a small success...old ini... home and homeoffset to zero.. jog to marked position (edding/sharpie on the joint..).. then homed to index.. bring all in a non singular position... start g code...

I think this was a step in the right direction... but z stays not on z on the table.. but on the linuxcnc dro
 

Are you saying Z does not operate correctly on the machine although it displays correctly in the DRO? If so then I would first suspect the problem would come from having some joint not zeroed at the exact true zero point. I think a slightly incorrect DH parameter would create the same symptom.

Ok, I did not know about that is an original Chinese design, thank you for your observation. and comments. and thank you for this card that give me the chance to deploy a laboratory over this card.
If some one has been testing this card, please share you experiences and conclusions

But what was on lines 1-4? The screen shot of your code does't show. It would have been better (and used less bandwidth) to upload the actual g-code file, rather than an image of a screen shot.

To analyze problems with gcode, it is so much easier to load the relevant file into your own simulation and test it than to look at a screenshot and make some assumptions...

Error in tool_offsetview.py

1) grid
It was never intended to switch sizes on g20/21.
But I see in the metric sim the mm sizes are not metric at all.
strangely in the inch sim, metric and imperial sizes work properly.
This seems to be in the glcannon code, so is not fixed yet.

2) paused runtime
ya that's not right and I think its fixed now.

3) mode switching
I created a hidden 'auto mode switch' option - enabled in the preference file only.
I think it does what you want. please try it out and if it is I will make it a settings option. (if running a program, the file tab will still not change to the file page FYI)

4) keyboard pausing
ok I removed the mode check so it should work everywhere.
I could not get the spindle lowering to fail with the pause button after this.
please advise if there is more to look at.

All just pushed to master

tommylight post= You did neither, seems you are hiding something...
Yet you ask us for help.



I have to trim the size of the image down otherwise I get an error saying the image is too big.
If for some strange reason I decide against my better judgment to come back here again and ask a question, do me a favor, don't reply to it.
I really don't care if you know the answer. I am going to ignore anything you post from here on out. If it was possible to block you from seeing anything I post here, I would. 

Have a day you deserve.

LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

Category: Computers and Hardware

You’re right, it’s actually too small for a full setup.

But you could use it, for example, as a satellite, as an extension or for a distributed setup.

www.youtube.com/shorts/2vjq0Kd5WOE


In principle, a single-axis setup would also work, though it’s always a bit tricky to have mixed setups.

I’ve done a test compile:



Resources | Usage | Utilization
Logic | 956/1152 | 83%

and it fits :)

with USB/Serial it's to slow.



EDIT: BTW, the boards in the list are just the ones that have pre-defined pin assignments and can therefore be used easily in the Flow frontend. However, it’s also quite easy to add new boards, or you can let me know which ones you’d like to see included – as long as the FPGA supports them, it’s no problem.
