Bah.  T'was lucid (I typed wheezy because I'm an idiot :-().

But I've bitten the bullet, installed jessie and linuxcnc 2.8 (the
attempted upgrade from lucid to precise didn't go well).

Not seen it move anything yet (I'm doing the install/setup from my desk
rather than in the workshop) but everything seems to be coming alive.

Not really a solution to the problem I was getting but most certainly a
'work around' :-)

Can you clarify? Originally you said "Debian Wheezy" and now you are
saying "Lucid"

Have you looks at the file "axis.ngc:" using a text editor or using
"less" in a terminal?  What do you see near line number 12?  The first
thing to do is always assume the r=error message is literally true.

Perhaps what has happened is that a number in the file has been wrong
all along and now the newer software does a better job of catching
errors in the files it reads.  The problem be syntactical or logical

One other debug method I use that works with open source software is
to search for the error string in the source code.  Then it is pretty
easy to see the condition that would cause it to be printed.

Maybe try things in a different order? (LinuxCNC then NativeCAM?)

I think that a lot of the NativeCAM examples assume 2.8 / JA which was
maybe something of an error.

What version of python do you have on that?

I did a google for upgrading python on lucid to 2.7 (needed to build
linuxcnc from git) and found dire warnings about breaking things.

I might just try an upgrade to precise...  can always restore my current
setup from backup if it goes titsup.com

I am fairly sure not, as I am running 10.04 on my milling machine, and
that is on 2.8-ja1.

Unfortunately I can't recall how I got there, but probably via the buildbot.

The heating's come on today so it's probably expanded a bit but not that
much :-)

Hm.

A) that doesn't explain the weird error message about axis.ngc.
B) the same position.txt works with 2.7.4
C) deleting position.txt doesn't fix either problem.

FWIW, position.txt contains:

211.51237592697140144

I've just tried sim axis_mm.ini with 2.7.7 and it also generates the

Created a new user (to avoid config issues), logged in, ran 2.7.7 and
picked sim.axis/axis_mm..  same popup error message about "Bad

If I try to open a previously used simple .ngc file, linuxcnc complains

When I click pause to continue, I get the error "can't do that

Uninstalled 2.7.7 (apt-get remove --purge linuxcnc), reinstalled 2.7.4
(apt-get install linuxcnc=1:2.7.4) and, still as my new test user, fired
up linuxcnc with sim/axis_mm.ini.

No complaints about bad characters, no silly numbers on homing and the
sim happily 'cut' LinuxCNC as expected.

Just for fun, I tried 2.7.5 and it's borked in the same way as 2.7.7.

Tried building a git pull of linuxcnc-dev but configure fails saying
python is too old (2.7 needed; lucid has 2.6.5).

Somethings very broken with 2.7.5+ on lucid :-(

So...  am I stuck on 2.7.4 ?

Is this one of them "Universal" milling machines, for milling entire universes?

At a guess, the problem is the exponent notation, it tends to get sent
into python as text, then into G-code where the "E" words confuse
matters.

It might be as simple as a position.txt file with bad numbers in it?

[Emc-users] Problem upgrading from 2.7.4

2016-10-12 Thread Russell Brown 

I tried upgrading from 2.7.4 to 2.7.7 (debian wheezy, apt-get) but when
I fire linuxcnc up I get a popup error message:

>G-Code error in axis.ngc
>
>Near line 12 of /usr/share/axis/images/axis.ngc:
>Bad character 'z' used

If I click 'OK' linuxcnc loads but the initial X & Y show as 4.23e+289
and 2.95e+240 and axis.ngc is not showing in the display.

I then tried 2.7.5 and get the same thing.  Downgrade to 2.7.4 and
everything's back to normal.

axis.ngc sums as 16239 (same as my backups) so I don't think it's that.

A possible contributor to the problem is that I tried installing
NativeCAM but ran into problems as I already use gladevcp for a probe
screen (I'll go back to that once 2.7.7 is working).  I ran "setup.py c"
clear NativeCAM for now.

Any ideas?



(my .ini is here http://ruffle.me.uk/Mesa_Mill.ini.expanded)

linuxcnc prints

Not sure about those Gtk warnings... they might have been around forever
as I normally fire up LinuxCNC from an icon.
