emc.hh -- hal_priv.hh --- etc etc not find

Category: HAL

@Tommilight .... please these problem is related to these post forum.linuxcnc.org/9-installing-linuxcnc...n-edition-6?start=70 ... so if possible joint these two ......

Tomorrow check why I've not linuxcnc/emc folder ..... or emc folder on my pc. Very strange because Axis work and ethercat too .... today I moove a ethercat servo without issue ....

Regards

The file interfaces contains the following:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

auto enp1s0
iface enp1s0 inet static
address 192.168.1.120/24
hardware-irq-coalesce-rx-usecs 0



The output of the command can be seen in the appendix.

Hi Arciera,

This is one of the first formula's to actually solve the clothoid spline.

It looks like 1.0 is for z trajects. Then the zero is knot zero. Begin of spline.
It looks like 2.0 is for xy trajects.

It looks like 1.4 is for z trajects. Then the 4 is knot four. End of spline.
It looks like 2.4 is for xy trajects.

Then you can say i=1, j=2. You have a set for z values, and a set for xy values. Because curvature is not only
on xy plane but also in xz plane.

 

I still don't fully understand the first formula, the short one at the top.
I think its calculating the "angle start" parameter for the z component.

Somethings is wrong .... I check now master branch on github and that file already exist ..... so seems my LMDE6 linuxcnc have somethings of wrongs .... not exist xxxx/linuxcnc/emc/ folder in my istallation ....and is not a .rip installation ..... master is now 2.9.2 or 2.10?? think use 2.9.2 because some library not avaible in LMDE6 ...

The entry in the interfaces file should do it but unfortunately
you don't get an obvious warning message if there is a syntax
error in the interfaces file.

You might try:

ethtool -c enp1s0

To see if your interfaces file setting was actually run

I think F360 could be coaxed in to spitting out all the longitudinal moves in one go.
  • Draw an axis down the rotational axis of your part
  • Create plane at angle, using the axis line
    • Project the cross-section of the part (body intersect) on to the plane
  • Create pencil toolpath along the 'top half' of the projected path
  • Repeat the plane & projection as many times around the same axis as you need resolution.
    • Would depend on the resolution of the burned/melted area your soldering iron tip creates - which likely varies depending on temp and 'feed-rate.' Might need 36 planes, might need way more.
  • Repeat toolpath for each rotational angle plane, using tool orientation to adjust the "A" axis (in your case it'd be the C-axis)
Posting the gcode should result in a single file with a series of longitudinal moves (Z) with varying X values along the part profile, repeated for each A-axis orientation.

I wonder how deep you could dig with each pass? I was imagining something like a loop-shaped hot wire knife scooping off great big ribbons of foam like Godzilla's own apple peeler.

Hello,
if I enter the following 

   auto enp1s0
     iface enp1s0 inet static
     address 192.168.1.120/24
     hardware-irq-coalesce-rx-usecs 0

in the file interfaces then the hm2.readTime deteriorates from 800000 to 900000. I have entered everything manually, it cannot be a character set (e.g. at -)
If I enter the following command.
     sudo ethtool -C enp1s0 rx-usecs 0
Then ping and readTime (250000-400000) improve significantly.

Is there a possibility to use the command
    sudo ethtool -C enp1s0 rx-usecs 0
automatically when starting LCNC?
If so, how?
perhaps with grub?
Greetings

There is a text :
i=1,2;
for j=0,1,2,3,4 are the knots of the spline, this i understand. But do you get what i does?

I haven't really looked at the paper closely but here is what I think:
If you look at formula (14) you see that the 3d clothoid has two sets (i=1,2) of four parameters (theta, kappa, c , gamma). So 'i' stands for which set of parameters we are looking at.

Both fanuc and siemens fit splines for high speed motion

Yes. What I meant is that nobody uses splines in the Gcode they load into the controller and thus the spline-related Gcodes implemented in LinuxCNC (ie G5, G5.1, G5.2, G5.3) have really been a solution looking for a problem. That is why I say that they are pretty much useless, _unless_ the can be repurposed for something new like internal path blending.

Hi Arciera,

I'm afraid I can't help you with implementing the linked 3d clothoid algorithm.
I have used chat_pdf ai yesterday. This works quite good, but stops and ask's money.
However i don't understand in the page at section (23)

There is a text :
i=1,2;
for j=0,1,2,3,4 are the knots of the spline, this i understand. But do you get what i does?
Thanks.

@IhaveNoFish,
get used under the hood
Indeed.

watchdog and network connection problems

"i was getting the red light when i powered on the board with debian 12"

This really does not make any sense as there is nothing the Ethernet/host connection
can do to illuminate a red LED on the 7I96S other than by running LinuxCNC.
(exiting a LinuxCNC run _will_ result in a red /INIT LED being illuminated)

Can you run this command:

sudo chrt 99 ping -i .001 -q 10.10.10.10
 hit control C
then run it again
sudo chrt 99 ping -i .001 -q 10.10.10.10
wait about a minute and hit control C again
 and copy paste the results here

but on new 2.9.2 seems is not used anymore ... someone can indicate me actual file that make the same in Lcnc tree??
thansk a lot.

I'm not sure this is entirely true.
Both fanuc and siemens fit splines for high speed motion. We definitely don't need the g code to describe a spline, but it does often get used under the hood to help describe all the pointes BETWEEN your g1 end points.
