Re: [Emc-users] axis-remote in M-call problems

[Henrik Munktell]

Hmm, ok I understand what you are saying. But why is it taking so long to
execute when M155 is in sub and not when I run the command in mdi mode?
Maybe it's hard to call it a bug before we now exactly what's going on
here.

Is this different from the behaviour with the same file if you press
the Axis "reload" button?

Hi Chris - Here's part of the code - it's obvious early on without all
of it. I'll post the config tomorrow - machine is at work.

BTW - Changing N190 to

N190 G64 P0.5

and it runs better, but that's far too much deviation.

I have not personally used that command, but I would assume that the reload 
command probably re-invokes the initial code scanner to check for legality 
of the moves.  I wouldn't consider it a bug at all, but a safety measure.  
And yes, it will be frozen and ignoring you and the machine both, so I 
would as a normal coding style, make sure the machine is clear of the work 
and axis motion has ceased before I would invoke that line of code.

OTOH, I could be full of it.  It wouldn't be the first time, and likely not 
the last, but common sense is how I'd read this "bug".  YMMV of course. :)

Cheers Henrik, Gene

[Emc-users] OT: PCB milling / GUI for pcb2gcode

[erik]

Greetings.

For those who use pcb2gcode to generate gcode for isolation routing:

I wrote a small Python GUI for pcb2gcode and would like to share it. 
Maybe the programm is not only useful for me :-\

Your can download the latest source code from my homepage if you are 
interested:

Any feedback is very welcome.

[Emc-users] running in sim mode, need more screen for debug output

[Gene Heskett]

Greetings all;

Where in the sim/axis config, do I tweak to get the additional window space 
on the right, where we put tachometers etc?

I am trying to debug some code, but the debug output is covering the 
backplot, making the backplot unusable for correlating moves vs debug data.

Thanks everybody.

Cheers, Gene

Re: [Emc-users] Poor CV

[John Stewart]

Probably a dumb question, but, what acceleration values are you using on the 
LinuxCNC setup?

My little mill was transformed when I added a 5i25, and really looked at what 
some of the values are. It now runs up to 10x faster than before.

Two values were tweaked; acceleration, and max velocity. 

Now, I know there may be other issues, but the first half of your clip looked 
like my mill before, the second half after. 

I could be off in left field on this one, which would not be the first time!

Those are clear text servers, not encrypted, and not very secure.  sftp, as
Jon mentioned, is a child process of the sshd server.  Everything is
encrypted, from the log on to the file transfer.

If you prefer to use Windows, then I think you can build the firmware
entirely in Windows.
There is nothing "Linux" about the FPGA / Hostmot2 firmware.
Try working with the Windows version of the Xylinx tools.

Re: [Emc-users] Poor CV

[Anders Wallin]

Can you post the G-code for this somewhere? Do you know if the G-code has
strictly continuous direction(tangent) or better yet: continuous curvature
(acceleration)?
Did you try different G64 tolerances? What tolerance does Mach3 use?

Can you log the actual position of the machine and compare LinuxCNC to
Mach3 ?

Better blending/lookahead is a periodically recurring theme here! :)
However the problem is hard enough for the average hacker not to make much
progress during a single weekend - and I think that's one major reason
there hasn't been much work in this area.
It probably requires a focused effort by people who have commercial
interest (araisrobo on github?) or in an academic setting (i.e. motivated
by getting a degree from it).

My suspicion is also that better lookahead/blending will require making
some assumptions about the kinematics used. So far there's been only one
code-base which is capable of handling all kinematics, but I think the
blending problem could be substantially simpler for 3-axis trivial
kinematics - which probably covers a large fraction of linuxcnc users.
