Re: [Emc-developers] problems with stretch/uspace install

[Jon Elson]

Are there up-to-date release notes for LinuxCNC?  There is a 
release notes file in the Wiki, but the last entry is 
February 2016 (2.7.4)!  There seems to be some 
incompatibility with my configs files sets and the 2.8 
release, and I need to make whatever changes are required.  
I see a lot of differences between some of the usual 
boilerplate, such as related to EMCMOT.


Any suggestions?

Thanks,

Jon

The biggest thing I can think of is the joint-axis merge, which is still 
a bit incomplete, requiring matching, duplicate entries for some of the 
vars used in the .ini file.

Perhaps Andy can state it a lot better than I can. There is supposed to 
be a onetime script that scans and edits your configs and fixes 99% of 
it on the first execution of older /config/ files.

They are not duplicates. Though with a trivkins machine the values
will typically be identical. :-)

Humm, all of mine including the 4 axis mill, must be trivkins then, and I 
believe the aliases make it so, cause a one digit miss-match in max or 
min limit of the axis and corresponding  joint is an absolute show 
stopper. Same with max_vel and max_accel.

Anyway, this is not fixing Jon's problem.

Seeing a copy/paste of the actual report would be most helpfull.

Thanks Andy.

I just remembered this after compiling some new stuff and updating my lathe.
I lost this tweak.

I have been using it that way for over a year with no problems, can I
push the mod?

[Emc-developers] Absolute resolvers

[andy pugh]

Using the position.txt file and a tweak to the Mesa resolver driver I
have had good results making my lathe work as if it has absolute
encoders.

Does anyone have any opinions about whether I should, or should not, push it?

Naturally it would need docs, but you basically just need to connect
joint-pos-fb to the resolver module so that it can see the value read
in from the position.txt file and set a bit parameter to say "wait for
that value"

This should also work for any 1 turn absolute encoder (like the common Hall 
effect encoders from AMS etc)

It should, but the drivers need to be modified to support it. And I
don't have any to test it with.

Thanks, this is what I was looking for!
Well, the automatic script did its thing, and looking 
through the .ini and .hal files, it appears to have done a 
good job.  I can't find anything wrong except the shmem_key 
on trivkins, which I took out.


So, now on a fresh startup of LinuxCNC using my boards and 
the ppmc driver, the ppmc driver enumerates the device(s) on 
the parport, then I get :


waiting for component 'inihal' to become ready

with periods ( . . . . .) constantly being written.  After a 
couple seconds, the mouse pointer stops responding, and I 
have to do a forced power off.


This one sounds real familiar, but I can't remember what to 
do about it.


Any suggestions?

Thanks,

Jon
