Heres the (really long) list of changes from 2.6 to 2.7 http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Released_2.7.X Two really major changes are the new trajectory planner (considerably faster for profiling type operations with lots of short segments), and the uspace branch which allows use of the Preempt-RT real time Kernels as an alternative to RTAI. the firmware updating is only for mesa sserial remote devices that are more than a couple years old, 2.7 complains about old firmware (but will run) > > >> -----Original Message----- >> From: John Alexander Stewart [mailto:ivatt...@gmail.com] >> Sent: September-05-15 9:24 AM >> To: Enhanced Machine Controller (EMC) >> Subject: Re: [Emc-users] Mesa software out of date error? >> >> >> Ok - *just* got it working. >> >> For those with the "insmod" error, >> - you run the "update7i76" as non-root (as per the readme in >> sserial.zip) >> - make sure you have field power turned back on; the module will NOT >> load >> without the 7i76 powered up. >> >> When I slapped my forehead, got the 7i76 powered, the update went just >> fine. >> >> LinuxCNC now reports (via Show Hal Configuration) that I have gone from >> SW >> version 0X0B to 0X0E, and the warning/error is no longer shown at > startup. >> >> Peter - thank you for these utilities, and for your constant emails/posts. >> I did find >> the 5i25 update on the linuxcnc forum, which helped considerably. >> >> :-) >> >> John. >> >> >> >> On Sat, Sep 5, 2015 at 12:16 PM, Peter C.
