Are there any reasons I should not attempt 2.8?
Not that I can see. It has a few subtle problems still, but only in unusual
or especially demanding configurations.
If your router are the two-motor gantry design then 2.8 offers genuine
advantages such as auto-squaring during homing.
You can configure your system to pull binaries from the buildbot. This is
quite a lot like running a normal system except that updates happen
somewhere between weekly and several times a day. And sometimes you can end
up with a broken version in master.
However, 2.8 is now locked into "bugfix and repair" only so should only
ever get better.

Is there anything I can do to help nudge 2.8 along?
Good question. In theory mozmck is in charge as the release manager. If you
feel particularly enthused you could look at the issues list and see if
anything looks fun.

If your school does computing as a course then it would have been nice if
there was a "good first issue" to use as an example exercise (but nothing
is tagged as such)
Maybe #610? (though that isn't blocking 2.8, I don't think). That doesn't
go into the scary deep layers of LinuxCNC where even the long-timers get
lost.
Andy,
Thanks. I started looking at 610. In the simulator escape exits right
way. It looks like src/emc/rs274ngc/gcodemodule.cc parse_file() won't
return because of the infinite loop in the gcode. It seems like there is
a callback that checks for the esc key being hit, causing it to abort
the load. I'm not positive I understood the code correctly.
This was against the code in master. I can try on our old machines next
next week.
The school does offer a java based computer science course, but I'm not
involved in that at all. For robotics, the kids use National Instruments
LabView and their roboRIO controller. Other mentors handle that. I
mainly work in the shop, helping the kids run the manual mills, lathes,
and of course the CNC Routers. We cut a lot of the parts for the robots
out out of 0.090 aluminum sheet, plastic etc.
Regards,
Andy
