Re: Would this motor record documentation be considered "current"

[Torsten Bögershausen via Tech-talk <tech-talk at aps.anl.gov>]

Now,

I would say that this document is not fully current.
- It seems to describe the model 1 driver
- It misses the model 3 driver "framework", which is what
  is used for all modern controllers.
- The Chapter 3.3 Backlash seems wrong.

I don't think that there is a difference between EPICS 3 and 7
regarding the EPICS motor module.


What information are you looking for ?

The "official" documentation is here:
<https://urldefense.us/v3/__https://github.com/epics-modules/motor/tree/master/docs__;!!G_uCfscf7eWS!bcxx9VUxVgj00rhv7GcRujSbI-VVEzfqzYfZbdlNlgPVpX63Dmc661WHUFNZwXo52oV7GMu64E0WgVPhsPQ$ >

And then I gave some introduction here:

<https://urldefense.us/v3/__https://github.com/EPICS-motor-wg/epics-mwg-discussions/blob/master/documents/2024-04-16-MotionTraining-at-PAL/3-MotorRec2024-v4.pptx__;!!G_uCfscf7eWS!bcxx9VUxVgj00rhv7GcRujSbI-VVEzfqzYfZbdlNlgPVpX63Dmc661WHUFNZwXo52oV7GMu64E0Wcco47Ts$ >
