Hello!
Is there a good document explaining how to develop a model 3 device
support for motors?
Thank you,
Márcio

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:

Thanks Andy
Yes, I had found that one also - however that one feels much more an
index of definitions than a narrative on how to get started :-)
I’ll try following them in parallel to see if I can get an idea of where
things deviate… though maybe EPICS 3 and 7 deviate little in this area?
All the best Graeme

Good morning
Before I start committing too much of this to memory or putting it
into effect, would this be considered “current”?
