UH, too hard to me, not understand anythink this all code, but need use touch probe tool height setting only.

how install and use if not newer before has understand code, or hal or ini or what all this need and what all have. and were have. not understand code.

It looks like you are still running the old version of ethercat master.
I look at this message in syslogThis means the EoE code is still active in the ethercat master.
When EoE is removed from the master, all messaged with EoE will disappear.

Make sure to remove the debian/apt installed version of the ethercat masterThen re-compile and re-install the new version of ethercat master.
Also, the configure statement I told you was wrong (sorry about that), it should beand continue to install according to INSTALL.md.

When you have the ethercat master up and running again, check the syslog. There should be no EOE mentioned.
This must work, it is all dependent on that EoE is removed.

i used hard stop homing on many machines with mitsubishi/yaskawa servo drives. all of them have a "torque limit" input and a "torque clamped" output. so just connecting

joint.*.homing => servo-*.limit-torque
joint.*.home-sw-in <= servo-*.torque-clamped

does the trick.

and here's the video when i'm using "torque-clamped" for motion.probe-input. with z axis driven by 2mm pitch sync belt on 20 teeth pulley it is able to resolve silkscreen paint thickness on a PCB...

Oh no, something else not quite right with my build. The halrun binary seems to be missing. I will try to find out how that dropped out. I will need it for the project where I plan to use this pi3.

Another latency test. The previous one I shared was run a couple minutes with nothing else running. This time I gave it the works. How about 10mS latency.

Here are the error reports I get trying to wake QtDragon. seems to be a complaint about the ngc path. I'm using run-in-place. I've got to look at this again. Just writing it up gave me more ideas.

Wow, I can hardly believe I did this to a pi 3. The simulation is running. Next I want to check if gpio and a couple other basics work. The latency numbers look a bit sad.
Still no luck starting QtDragon.

Sorry to hear about the accident. That work you shared looks nice. Someone had it about all figured out. Wish I could help out. Dunno, my own wiring schematics are just scribbles on paper.

That is interesting. One of my friends is building cnc plasma tables, he uses his favorite proprietory software (Centroid), along with ClearPath servos. I don't recall whether we ever talked about his homing. Next time I meet him I might remember to ask how his system does it, just out of curiosity.

I am having the same issue, I tried to modify my io.hal file as suggested but i am getting an on/off dance in hal show with no indication of probe trip. I have attached my original hal file as well as the actual one I modified. 

I finally got around to wiring up and adding the logic for my pendant and it now jogs. I even messed with the PID well mostly P so the axis actually move at a reasonable speed without tripping out. This is going super well, I just need to work out a small scaling issue. Seems like it moves about 90% of the command in real life so my encoder counts are likely off. The last big hurdle is getting the gear shifting logic to function and then I'll be off to the races with being able to machine some parts with it. The conversion had a small interruption of purchasing a bum tractor that needed some major work but that is mostly behind me now and I have a bit more room to mess with the mill again.

FWIW Tormach does hard stop homing on their ClearPath machines. I retrofitted my Series 3 with them and honestly it seems to repeat pretty well. Certainly better than 5mm. I haven’t done an experiment to precisely measure it, but I’m fairly certain it’s within a .001” - .002”

I attached dmesg file which is
refClockSyncCycles="-1" version.

(PS)
I have to add this info.
I tested multiple times this refClockSyncCycles="-1"  version.

sometimes (33%?) , No alarm , and I could Power on (servo on) and jog moving.

But sometimes ( 66%?) I can't control servo motor at all from the begining after execute LinuxCNC.
In this case, CiA402 status=0000.  if I pull off and push in  (reconnect physically) EtherCAT cable several times, sometimes get correct status,
and after that I can control servo. ( not all the times )




 

thank you so much. but I still have a problem.


sudo make modules_install install
sudo depmod
sudo echo KERNEL==\"EtherCAT[0-9]*\", MODE=\"0664\" > /etc/udev/rules.d/99-EtherCAT.rules

I got error>> bash: /etc/udev/rules.d/99-EtherCAT.rules no permission
So I fixed to 
echo KERNEL==\"EtherCAT[0-9]*\", MODE=\"0664\" | sudo tee /etc/udev/rules.d/99-EtherCAT.rules

sudo systemctl daemon-reload
sudo systemctl start ethercat

ethercat version
IgH EtherCAT master 1.6.8

ethercat slaves
0  0:0 PREOP + SGDXS-xxxxA0x EtherCAT(CoE) SERVOPACK Rev02.09

and then, I executed LinuxCNC with my simple config.

But nothing has improved. 
I attached dmesg. 

And then , what I did was.. syncToRefClock="true"
>> I got error, and LinuxCNC did not started.

refClockSyncCycles="-1"
>> I got LinuxCNC Terminal output "Failed to get reference clock time: Input/output error" (20 times )
What am I missing ?
