Which came out well and I pigged out.  That in turn put me down for the 
count for a couple hours, probably too much sugar.  But I recovered, 
drug the toolbox out, opened up the back panel where all the spindle 
electronics live, and spent 20 minutes blowing the swarf out of things.  
Covered it back up, fixed the x axis drag chain a bit better, and 
finished one end of a bearing pusher before calling it a night. Added 
some code to take care of some of TLM's built-in taper, guessing 
at .003mm/mm for external turning, bigger toward the chuck, must have 
been a good guess, my calipers can't find any taper at all in what I 
just did.

However, when boring I know it will take more than that as it bores small 
at the chuck, and at least 15 thou an inch bigger as it moves toward the 
entry of the hole. That, I've given up trying to find the why.  Internal 
taper and external are off in the same direction, but internal is 
several times worse. I keep forgetting it was a $350 Speedway off the 
Chicago Tool Touring truck parked at the local VFD for a one day sale 
back in the late 90's before I retired.  A Hardinge it isn't. Someday I 
might get a better "little" lathe.  If I last long enough. :)

The fix was temporary, I had been watching it while fineing up the size 
of the bolt hole thru a block of alu, thinking it ought to be big enough 
for the bolt (it was) but something happen inside the motor doghouse 
just as I slid the feed override to 0.

I keep forgetting to re-engage the backgear, so the pid spins the motor 
wide open when the spindle doesn't turn, so I had put a 100 millisecond 
timer, retriggerable, netted to shut the motor drive off again by 
disabling the machine if an encoder pulse has not been rx'd within the 
timeout.  And thats where I am.  So I've got to wrestle the wheeled  
toolbox its sitting on, back out of its cubby hole, and uncover the 
doghouse to see whats happened.  I've had so much alu swarf flying 
around I will not be surprised to find a curly bit of it someplace its 
not supposed to be.

But Easter Sunday dinner awaits, by baby felt like doing some of the 
cooking today.

I just found that about half an hour ago, on at least the 3rd or 4th read 
before it sank in.

I believe it may be fixed now.  I'll find out for sure come daytime 
again.  Thanks Phillip, for not calling me an idiot who can't RTFM.

Poking and prodding with the lathe, I turned on debugging to 0x7fff 
and ran it, and I note in the terminal a couple things that look odd, 
but I don't have a working lathe to compare it to, so I'll paste them 
here.

task: machine: 'The Little Monster'  version 'unknown'
emcTaskOnce: Python plugin configured
emcTaskOnce: extract(task_instance): KeyError: ('task',)

emcTaskOnce: no Python Task() instance available, using default 
iocontrol-based task methods
emcTrajSetJoints(2) returned 0
emcTrajSetAxes(3, 5)

The config does have a LATHE=1 in the display section.

And only XZ are specified anyplace.
gene@lathe:~/linuxcnc/configs/my_LinuxCNC_machine2$ grep -i xz 
my_LinuxCNC_machine2.ini
GEOMETRY=   XZ
JOG_AXES=   XZ
COORDINATES =   XZ
KINEMATICS  =   trivkins coordinates=XZ

What does the above tell us?  Line by line please.

Thanks all.

Cheers, Gene Heskett

I have just checked again with both sim/axis/lathe and 
sim/axis/historical_lathe.

Keyboard jogging before and after homing works as it should:

left/right arrows move Z and up/down arrows move X

mdi moves are also moving correctly

Touring what could have been hell, I just installed that version on both 
of my mills, and things appear to be working as expected on all 7 axis's 
they have. So this seems to be a lathe only problem. That should help 
narrow the search.

I also, for lack of anything better to do, rigged up my chop saw and 
sawed off a couple hunks on 1.5" thick alu to make a new set of bearing 
pushers to fit the larger OD of the correct bearing. Fired up 
linuxcnc -l, (this after an early morning update of LinuxCNC-2.8-pre to
LINUXCNC - 2.8.0-pre1-2988-ge9f9469) x and z are still swapped at the 
keyboard yet before being homed. Hit ctl+home, and it homed to the 
correct places, and in the correct directions and homeing order. Tapped 
the uparrow, then downarrow, and z moves left-right.  Tapped the left 
and right arrows, and x moves in and out.  Switch to MDI, and its now 
scrambled as well, as in G0X moves Z and G0Z moves X. So it appears 
Phillips commit made the keyboard scramble apply to MDI too, which means 
it cannot run code I ran on it just 2 days ago.

Help! I do not have another functioning lathe now.

Can you back out Phillips commit and retrigger the buildbot? It at least 
ran correctly after being homed, and I could use it, once it had been 
homed.

Thanks guys.
