Ga!

Chuckle, VBG etc, thats one of Murphy's laws, un-repealable. I'll get it 
after dinner.

Been using it all afternoon, after Peters suggested fix was applied, and 
my errors set back to their usual, carving up that long bar of cold roll 
to make a better x-home switch activator. But I've not yet readjusted 
the .ini file, dinner time, except my lady says her tummy isn't quite 
ready for the dregs of a crockpot full of pork roast and stew veggies I 
made Friday night. I can wait.

Thanks Andy.

Ah so, said the half-blind guy while calling up a copy of geany to put my 
following errors back to the previous normal. :)

And since the feedback is from the stepgens, not a motor encoder, it 
happily runs at over 100 ipm with the former error settings. Without 
motor power right now. :)

However, Andy said he pushed a function key fix, but I didn't get it with 
an update just now. I assume the buildbot hasn't run yet. Tomorrow 
maybe?

Thanks Peter.

Re: [Emc-developers] My g0704 is unusable after the last week or so's updates

[Peter C. Wallace]

Greetings all;

I went out in my half blind condition, found a bar of cold roll to
make a different x-home switch activator for the g0704. Fired up
LCNC which came up normal, but was not moveable for homing or by
jogging without an instant following error. Putting a halmeter on
the joint error, it was reported to be in the #-16 to #-18 range.
Danged close IOW.

My following error setting have been min=0.0005 and ferror 0.001 for
many months.  Without any problems.

Tonight I find I can't jog at above .05 ipm without resetting them
to min= at least .0025", and ferror at least .005", or nominally 5
times the working errors of around a month ago when I was making all
those tap hats. Once the error settings exceed the backlash, it will
move at close to 100 ipm in either direction of any axis.

So it seems related to BACKLASH, which worst cases are
GO704fast.ini:BACKLASH  = 0.00190 (x)
GO704fast.ini:BACKLASH  = 0.000950(y)
GO704fast.ini:BACKLASH  = 0.00320 (z)

Has anything been changed in that area of the code recently?

Thanks everybody for clues to check next.

The PID component changed a few months ago, so if your stepgen uses
the PID component and you updated the LinuxCNC version recently, you
may need to make some minor changes in the hal file (disconnecting the
pid.N.command-deriv pins)


Done, Peter but not tested as motor power is hand controlled on that
machine. As it is on the other 2, only the pi can power things up via an
ssh login.

Thanks Peter. Is there a new man page? I think I may be looking at the
old one.



The PID manual page is correct

(it always was, its the PID component that has been patched to match the 
documented behaviour)

Done, Peter but not tested as motor power is hand controlled on that 
machine. As it is on the other 2, only the pi can power things up via an 
ssh login.

BUT this might show what J. Ray Mitchel is encountering with his 
non-functioning F9-F10 buttons. Captured from the terminal screen LCNC 
was launched from. This should have activated my fwd/rev leds in the gui 
even if the tach stayed at zero, it did not activate the direction 
tallies:

Thanks Peter. Is there a new man page? I think I may be looking at the

Greetings all;

I went out in my half blind condition, found a bar of cold roll to make a
different x-home switch activator for the g0704. Fired up LCNC which
came up normal, but was not moveable for homing or by jogging without an
instant following error. Putting a halmeter on the joint error, it was
reported to be in the #-16 to #-18 range. Danged close IOW.

My following error setting have been min=0.0005 and ferror 0.001 for many
months.  Without any problems.

Tonight I find I can't jog at above .05 ipm without resetting them to
min= at least .0025", and ferror at least .005", or nominally 5 times
the working errors of around a month ago when I was making all those tap
hats. Once the error settings exceed the backlash, it will move at close
to 100 ipm in either direction of any axis.

So it seems related to BACKLASH, which worst cases are
GO704fast.ini:BACKLASH  = 0.00190 (x)
GO704fast.ini:BACKLASH  = 0.000950(y)
GO704fast.ini:BACKLASH  = 0.00320 (z)

Has anything been changed in that area of the code recently?

Thanks everybody for clues to check next.

The PID component changed a few months ago, so if your stepgen uses the PID 
component and you updated the LinuxCNC version recently, you may need to make 
some minor changes in the hal file (disconnecting the pid.N.command-deriv 
pins)
