To set the PID for the spindle speed, I had to set FF0 before setting P and I, otherwise it would go straight to maximum speed.
So, I started the same process, I reassessed everything, except for trying to set FF0 to 0 and only play with P and I.
I just did it, and ohhhh!!! It moves and stops (only for small angular movements, about 10 degrees, and it's not always reproducible). Above that, it's unstable and starts spinning at full speed.

Well, first of all, it's not a hardware problem, the hal seems to be working, I need to look at the PID values ​​again.

By being so obsessed with it, you end up losing sight of the basic elements... thanks for putting this back on track...

your orient pid params in ini file, their values is 0, why?
you need to gradually debug these values.
all are 0 it's wrong. At least P and D have non-zero values.

mux2_orient.out always remains at zero (-0.01397) and doesn't move.
And orient.poserr decreases

The attached halscope (in halshow, I can't display orient.poserr)

 

It maybeif your user is cnc.


If that is not the case this may help

Or you may have to search for "linux forgot password"

The required kinematic component can be found here:
github.com/LinuxCNC/linuxcnc/blob/master...ts/xyzbca_trsrn.comp

debug with halshow.

disable the spindle's motor,
run M19, then see if <mux2_orient.out> become less when u rotate the spindle manually to the right angle. the pin <orient.poserr> can tell u that if ur direction is right.

the expected result is: <mux2_orient.out> follows <orient.poserr> both become less, utill <orient.is-oriented> become true, so <mux2_orient.out> will be 0, means M19 is done, spindle could stop now.
if the pins work as expected, the problem maybe in pid component.

btw, i haven't configured a spindle orienting hal code with frequency converter, i use a servo spindle, orient in csp mode. it works nice and could lock at the angle after orienting.

Probably not the issue, but you should have these lines as the bottom-most addf linesThe addfs are executed in some order and these lines should be the last.

Hi, 
I have not used my CNC milling machine for some time and have forgotten the password to start LinuxCNC. Can someone give me some help in resetting the root password, please?

Hello,

I would like to be able to orient the spindle in position.

The spindle encoder is a 1024-line encoder connected to an EL5101.

I've already set up a PID to control the spindle speed. The settings could still be improved, but for now it works and is acceptable.

However, for now, I can't get the spindle orientation to work. I'm not proficient enough with HAL to see where the problem might be.
If I start an M19 R10, for example, the spindle starts spinning and never stops. I've changed the PID values, but to no avail.
I have the impression I have an index problem, and I can't see it in the HALscope.

I'll send you the HAL and INI files, in case any of you experts spot a bug...

   

Thank you in advance for your help.

"LATEST UPDATE" , after sliding board switch to NV, NVMPG shows XYZ, jogging works, nut steps are not accurate, some buttoms is not working, maybe then need to be "reprogrammed" after what signal it's sending.



OLD below here.
Following made, before I connected the NVMPG.
"UPDATE" , I think that the slider on the EC500 is in "STD" position, later today I'll try in "NV" mode.
ini file:
HALFILE = remora-nv-mpg.hal

sudo halcompile --install ./NVMPG/nvmpg.c

LinuxCNC do startup and run the simulation fine.
Where do I find the docs for NVEM and EC500 pinouts. If you know.

The trick here is probably

Thank you! It's HELPED!!
 

Ah, yes, I forgot, that sim config and kinematic is only available in the 'master' version.

[Edit]

you could install 'xyzbca_trsrn.comp' in your current version 2.9.4 using the 'halcompile' tool (you might need to install the 'linuxcnc-uspace-dev' package first): then you can change to the folder containing 'xyzbca_trsrn.comp'  and run

The 'xyzbca_trsrn' kinematic is now installed on your system and you could copy the simulation folder 
github.com/LinuxCNC/linuxcnc/tree/master...ndle-rotary-nutating
to your system.

My working setup...

5I25T config for 1 or 2 7I85S with 4 PWMs/4 Encoders/1 sserial port per 7I85S 

It worked. You were correct, I had to select the "Show Advanced Option Pages" for the discovery option to come up, and now I have all the steppers working. Thank you so much. I feel both relieved and a massive sense of achievement. Thanks for all the help and spoon-feeding me on how to do this.
