Re: [Emc-users] How do I get 2.8 installed?

[Phillip Carter]

I am not sure when it will be released, it can't be too far away.

You should be good to go using the 2.7-rtpreempt changed to 2.8-rtpreempt.

You could also download the the latest package from 
http://buildbot.linuxcnc.org/dists/stretch/2.8-rtpreempt/ 
<http://buildbot.linuxcnc.org/dists/stretch/2.8-rtpreempt/> and install it 
directly.

Re: [Emc-users] parallel port definitions

In that case the lathe would have:

loadrt hal_parport cfg="1 out" 

And the mill would have:

loadrt hal_parport cfg="2 out"

But again BOTH would have parport.0.blah-blah as it would be the first port.

Sorry, I reread what you said…

You would have two separate configs, the lathe would have:

loadrt hal_parport cfg="0 out" 

And the mill would have:

loadrt hal_parport cfg="1 out"

Re: [Emc-users] parallel port definitions

[Phillip Carter]

For that to work you would need something like this in your hal file:

loadrt hal_parport cfg="0 out 1 out 2 out"

>From what I gather you have two ports, one for a mill and one for a lathe.

So you would have two separate configs and one would have:

loadrt hal_parport cfg="0 out" 

And the other would have:

loadrt hal_parport cfg="1 out"

And BOTH would have 

parport.0.pin-nn-out etc. etc.

Because BOTH have only one parport therefore it is the first parport in the 
config.

Re: [Emc-users] parallel port definitions

[Phillip Carter]

It "should" work using 0,1 or 2 if not then you may need to enter the actual 
address

parport.0 refers to the first port configured in the hal file, if you had two 
ports they would be parport.0 and parport.1

Re: [Emc-users] parallel port definitions

[Phillip Carter]

In the Base Information page you can select the number of parallel ports

Then in the Parallel Port 1 page you can select the parallel port using the 
numbers 0,1 or 2 in the Parport BaseAddress entry 

Then in the Parallel Port 2 page you can select the parallel port using the 
numbers 0,1 or 2 in the entry that has no label in the bottom centre

Re: [Emc-users] Update: Re: linuxcnc versions

[Phillip Carter]

I just downloaded the wheezy iso from 
http://www.linuxcnc.org/iso/linuxcnc-2.7.14-wheezy.iso 
 and installed it 
without any issues using the GUI install.

It does give a warning about the debian-security repo but that does not cause 
any problems.

I was then able to run StepConf without any issues to create a stepper config.
 
Cheers, Phill

Greetings all;

I am about to give up on this bedwear comp project.

How I determine the amount of correction needed has been tried by
watching the dial as Z is moved, taking notes as to which way the
center of the wobble (the spindle is running about 15 rpms) moves,
and putting that DRO's RAD in the hal files lincurve "setp" list.
Makes it worse, change sign of lincurve y-val, still worse.  Seems
like the correction is being multiplied by 3 or more.

I have run it to a lincurve X-val-nn point, and using the jog dial,
centered the dials wobble on zero, then put the obtained rad into a
y-val-nn, again making it worse with either sign.

So how do you folks derive the correction needed?

I'm assuming the offset itself is in radius, not diameter. In which
case the needed radius correction max's at about 2.5 thou. And that
the sign is the "tricky" part.

Thanks everybody.

This lathe bedwear may be a good candidate for the
dgarr/external_offsets branch.

Re: [Emc-users] bedwear comp again

[Phillip Carter]

I note on my machine that joint.N.motor-pos-cmd and joint.N.motor-pos-fb 
change value after every homing and bear no relation to the actual joint 
position whereas joint.N.pos-cmd and joint.N.pos-fb are always show the 
same value at the same joint position.


Maybe the changes below will help.

LinuxCNC -l fired up from a terminal, and this is logged as it
quits: ./hm2-7i90-stepper.hal:262: Signal 'bedwear5' can not add
OUT pin 'joint.0.pos-fb', it already has OUT pin 'offset.0.fb-out'

But a search of the whole 700+ LOC can't find it.
oldtimers must be setting in, I can't see the error either. Sob.

It's on line 262, and that is probably right above, in your post.

But what I don't understand is why it is saying that joint.0.pos-fb
is an OUT pin, as as far as I can tell no such pin exists.
http://linuxcnc.org/docs/devel/html/man/man9/motion.9.html
There _is_ an OUT pin that reports the position feedback with motor
offsets removed: joint.N.joint−pos−fb OUT FLOAT

Your HAL, though, needs to have:

net bedwear2<=  joint.0.motor-pos-cmd => offset.0.in
# cmd from motion
#this is corrected command to x axis
net bedwear3<=  offset.0.out=>
hm2_[HOSTMOT2](BOARD).0.stepgen.03.position-cmd
# thats command, now fix the offset feedback back to motion
net bedwear4<=
hm2_[HOSTMOT2](BOARD).0.stepgen.03.position-fb => offset.0.fb-in
net bedwear5<=  offset.0.fb-out =>
joint.0.motor-pos-fb  X-axis-track.in

So the missing word was "motor". Fixing thar led to a duplicate error,
elsewhere in the file, and fixing that makes it run.  But now I've a
couple chops in the skillet and the rest of dinner laid out for the
microwave, so it will be after dinner before I get a chance to check
it.

One thing is bothering me about the halmeter readings from
lincurve.0.out though they look as if they've been subjected to a
large multipier, 1000 x or so and the max programmed is .x-val-01 is
0.0065", mainly to test the polarity of the corrections.

After getting us outside of dinner...

Next chapter; following Z motion for lincurve.0.in.
halcode:
# lincurve needs an input
net bedwear0 <= hm2_[HOSTMOT2]BOARD).0.stepgen.03.position-fb => 
joint.1.motor-pos-fb
# send the corrected fb to lincurve.0.in
net bedwear1<=  joint.1.joint-pos-fb=> lincurve.0.in # is supposed 
to be Z position

 From man motion: I finally printed me a copy for at the machine reference

joint.N.joint−pos−fb OUT FLOAT
The joint feedback position. This value is computed from the actual
motor position minus joint offsets. Useful for machine visualization

joint.1.joint-pos-fb does not exist according to linuxcnc.


My 'Show HAL Configuration' (from AXIS) shows joint.N.pos-fb yet the 
documentation (man motion) shows joint.N.joint-pos-fb.

The same for pos-cmd...

linuxcnc -l
[...]
./hm2/hm2_7i90.0: registered
./hm2-7i90-stepper.hal:255: Pin 'joint.1.joint-pos-fb' does not exist

The above is from terminal screen

Next? I'd rerun it and look for it with a halmeter, but of course it won't run.

This would allow me

I cannot otherwise take a skim cut while supporting on a center or run
it through the headstock.  Should save some time and frustration.

Otherwise,
they will always leave an annoying ring on a barrel.  Only way to

concentric with the bore.  Other option is to make a set of inboard

really depends on the spindle bore dia and barrel dimensions you
are working with.
