edited revert firmware page in teh docs
-
I had cause to roll back my firmware from 3.4-b6 to 3.3.0, and the instructions at https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3?revisionid=HEAD#Section_Software_Installation failed badly at the step 7:

It seems to me the first step of the instructions was wrong to say "only if reverting to v3.2", and you need that step also if reverting from 3.4-b6 to 3.3. So I've deleted the statement on dozuki.
If I re-revert to 3.4-b6 and then re-re-revert following the instructions but do remove duetpluginservice as step 1, it goes OK.
However, I'm somewhat ignorant here - copying out instructions without much knowledge about what I'm doing - so someone who understands it might want to review what I've done to the documentation.

@achrn this should downgrade you back to 3.3.0
sudo apt install \ duetsoftwareframework=3.3.0 \ duetcontrolserver=3.3.0 \ duetruntime=3.3.0 \ duetsd=1.1.0 \ duettools=3.3.0 \ duetwebcontrol=3.3.0 \ duetwebserver=3.3.0 \ reprapfirmware=3.3.0-1 \ --allow-downgrades``` -
@achrn Thanks for pointing it out, I've updated the docs again and removed the first step in favour of downgrading DPS via the last step along with the other packages.

@chrishamm OK.
It occurs to me that I might have added DPS manually, in which case the previous would not have affected someone that had not. However, presumably apt will take care of it if it's not installed.
