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.
Laurent

"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.

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.
