Re: [Emc-users] calling Todd Z

I'd be happy to merge it into either if there's demand. My recent batch of
changes restored the original behavior of the velocity field in EMC status,
so I don't think there are any other obstacles. One minor concern is that
the extra math slightly increases the CPU time for the servo loop, but I
doubt it will matter on reasonably modern hardware.

Rob,

We've been running this for a little while now and it seems to be working well 
for us.  Is there any plans to move it to the mainstream (Master or 2.7)?

That's consistent with the changes I made, that "velocity"  from the TP's
perspective is now along the 6D path (instead of just XYZ).

Maybe we could add fields / Hal pins for different interpretations? It
wouldn't be too hard to calculate XYZ-only velocity, and report it on a

Re: [Emc-users] calling Todd Z

2015-12-01 Thread Todd Zuercher 
Ok I got to test it again today some, and here is what I've found so far.  It 
looks like the g-code with Z and W are running the same as the only Z g-code.  
The same file runs for the same amount of time both ways.  

However I have noticed that it looks like the velocity display on the DRO, is 
adding the velocity of the W axis to the Z, so that when milling at F80, the 
DRO will show that the velocity was more than 80.  I'm not quite sure how this 
could be corrected or if it should be.  There are configurations where you may 
want the W and Z velocities to be additive (such as a knee mill) but that 
situation might be better served by configuring it more like 2 joints serving 
the Z axis.  I don't think it would be right to just completely ignore the W 
velocity either, because there are situations where the machine may be using 
only XYW for carving instead of XYZ or XYZW.  Maybe some way of only using the 
most significant velocity of the 2 (Z and W) in the velocity calculation, 
sounds like a recipe for making something simple (at least on the surface) into 
something very complicated.

Again, it is only what is being shown for the velocity on the DRO that I think 
is wrong, the actual movement of the the machine looks right, and the run times 
for the files seem to confirm that.

That's consistent with the changes I made, that "velocity"  from the TP's
perspective is now along the 6D path (instead of just XYZ).

Maybe we could add fields / Hal pins for different interpretations? It
wouldn't be too hard to calculate XYZ-only velocity, and report it on a
separate pin. Or, for backwards compatibility, I could tweak the status
update code so that motion only reports xyz velocity, even though
internally it uses xyzuvw.

Not in all cases XYZ are linear and ABC are angular. For example, 6-axis 
robots controlled from robot physics/kinematics savvy CAM G-code - all 
axes might be angular.

Some custom machines might use axes in all possible ways.

And all-axes smooth blending is very important thing to have, but 
different arc-blending tolerances for each axis is a thing to discuss.

Could they be programmed in g-code as some G64.0, G64.1, G64.2, G64.3, 
.. G64.8 parameters?
And / or set them from ini file at startup.

Any other / better suggestions?

Re: [Emc-users] calling Todd Z

2015-11-27 Thread Todd Zuercher 
A robot as you mention very well may have all angular "joints" but X Y and Z 
are still linear axis even if they don't directly correspond to any physical 
part of the machine.  (IMHO The day the fixes in the JA branch finally become 
main stream can't come too soon.)

Not in all cases XYZ are linear and ABC are angular. For example, 6-axis 
robots controlled from robot physics/kinematics savvy CAM G-code - all 
axes might be angular.

Some custom machines might use axes in all possible ways.

And all-axes smooth blending is very important thing to have, but 
different arc-blending tolerances for each axis is a thing to discuss.

Could they be programmed in g-code as some G64.0, G64.1, G64.2, G64.3, 
.. G64.8 parameters?
And / or set them from ini file at startup.

Any other / better suggestions?

Seems to be working great.  I haven't found a problem XYZ and XYZW code seem to 
run mostly the same now, but not exactly.  The first file I tested ran in 7min. 
10 sec. using only XYZ code (with the W slaved to Z) and the same file using 
XYZW code, ran in 7min. 28sec.

Sure, I'll give it a whirl tomorrow.  If I have time, and you give me a few 
pointers how to install the test.

Lately I've been running the routers with the W axis slaved to the Z using a 
bit of HAL trickery (it mostly works but flakes out occasionally.)
