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

Heeeelp thanks

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...

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.
 

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.

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.

I have a question.
At github.com/multigcs/riocore/blob/main/ri...ugins/fpga/BOARDS.md TangNano1K is marked as supported.
I know 1k gates is few, but is supported.
But I can't find any stuff for this board at repository.
I wonder is it possible to use this as one axis controller.
For example in situation when somebody have got working machine and could not make any changes to it, but needs to add 4/5th axis, rotary table, tools magazine or something similar.

Thanks for any replies. I managed to repair my machine for the time being, but I still want to upgrade the control system. I’m currently building a makeshift lathe so I can experiment and find the best control system. I’m planning to try LinuxCNC with the 7I96—since it’s constantly being developed—though I’m not sure if I’m capable of setting it up. Mach3 is no longer being developed, but it would be my second choice, paired with an Ethernet breakout board like the PoKeys57E.
Best regards,
Hans
 

Thank you for your help. The spindle PWM pin is now working.

         

The B3 drives can definitely home in the drive with a switch + z-pulse just like you said: you send a home command from a DO on the Mesa and the drive will return a signal back once done.
But it's possible it can also home internally using only the absolute encoder value plus some gearing table for the Harmonic Drive. I didnt even think of that but will scour the manual:)

That would be the cleanest solution, I think.

hi grandixximo,
what is the progress of adding this liscio type of curve smoothing to linuxcnc master.
-automata

ahh, sorry, you need to set the scale (signals/dty)

if your spindle max speed is 20000rpm, you need to set it to 0.005
# 100 / 20000 = 0.005

EDIT: will try to add a little helper-tool for easy setup

X,Y moving together sounds like a hardware/wiring issue of some kind.

Can you check if the cross talk is from the encoders or stepgens?

 

Ok!

Thanks

What me help:

If i jog in joint mode... what is correct?

J0 + turns it left
J0 - turns it right

J1 + lift up
J1 - lift down

J2 + lift up
J2 - lift down

J3 + turns right
J3 - turns left

J4 + lift up
J4 - lift down

J5 + turns right
J5 - turns left

I ask this because i am still wondering with my setup frlm the first ini i can move the z straight up and down x and y small dent or bend..

But on the end the inversekinematic fails.

Your idea is to bring the arm in a position where every joint is slightly + - 5 deg? To go out of the singularity?

Thank you!
