Excusez moi pour cette traduction un peu brouillon voici pourquoi j’en suis là j’ai suivi une personne sur le forum usinage ,qui m’a persuadé de Rétrofiter ma Deckel fp4a de 1990 avec les cartes mesa et linuxcnc il m’a guidé jusqu’à la mise en route mais cette personne a disparu je n’ai plus de guide pour finaliser mon projet c’est lui qui m’a lancé sur la configuration démo de linuxcnc les deux fichiers que je vous ai transmis.le descriptif que je vous ai donné au tout début de la discussion est fidèle à la réalité.voici les photos 

thankyou aceira, ive made some progress, got the easy probe and spindle panels into seperate tabs like the picture, followeed thee rest of the tutorial and got a few errors i thought id reesolve but when i tried it on the machine the probe tab does nothing at all, idk wether its because my probe is nc and thereees a -not i need to add somewhere or what. but its a steep in the right direction and it also works on 2.8.2 buster which mans i dont need to upgrade to 2.9 as it only has PREEMPT RT which is suited to mesa card and im using a 5 axis breakout paralell board. ive linked my files if anyone can tell m where im going wrong, btw the probes are wired NC, the tool setter is NC and the touch probe is NO but it has a physical relay wired before the toolsetter to make the touch probe NC until triggeeered so i can leave both connected permanently asd use th same input for both as i havee no more inputs on my BOB

Not sure, what does your config line look like?

One new issue though. The 7i87 works fine in mode 0 but linuxcnc fails if I set it to mode 1 or 2. I only want to use mode 0 but any idea why this happens?

All's well that ends well. The 7i87 card is now detected and its pins and parameters are visible in hal configuration.
Just a series of stupid wiring mistakes and wrong assumptions on my part. The final thing that got it working as realizing that TXEN doesn't mean TX Enable it means TX Enable NOT. Once I grounded it I saw nice clean differential pulses on the output of the TTL-RS485 converter.
Now I can work on the software.
Thanks for your help PCW.

Many thanks for your answers

I have made the following settings in the bios (based on a reset to factory settings)

Active Prozessor Cores ALL
Intel Virtualization Technology Disable
VT-d Disable
Intel TXT Support Disable
Enhanced SpeedStep Disabled
Package C State limit C0 - Which setting should be selected here?

LAN Controller Disabled
Azalia HD Audio Disabled

Launch CSM Enabled

Unfortunately, the values in the latency test have not really changed.
 

Next Step is trying the kernel parameters.

sudo nano /etc/default/grub

and add
isolcpus=3 intel_pstate=disable processor.max_cstate=0 idle=poll cpufreq.default_governor=performance ahci.mobile_lpm_policy=1 irqaffinity=0 nomodeset quiet

save and restart is there anything else to do?

cnc@cnc:~$ sudo update-grub

but it says no isolcpus ???



 

You can try running this script:

 

download and then:

chmod +x checkmask.txt
./checkmask.txt [Your-Ethernet-device-name]

 

Can you list what hardware and drives you have?
 

Thanks for your feedback I no longer know what to put on connectors 2 and 3 on N2 8i20 amplifier card and I have no corresponding card 

The scale should be 5000 if the scale resolution is 1 uM
With a scale of 5000, does the position (not the count) change by
1.000 for each mm of motion?

Other possible issues for add position numbers are wrong BISS setup parameters
or clock/data polarity issues.

How does encoder scaling work?

I have a magnetic linear encoder with 1 micron resolution (native 2mm pole distance with interpolation resulting in 1um resolution). My ball screw pitch is 5mm per revolution, so should my encoder raw count be 5000 pulses per revolution and the encoder scale 5000. The encoder spits some large number which seem to work in increments when I move the readhead but the readings are non sense large number like 254921 or similarly large number.
 

Hi,
I'm fairly new to linuxcnc and am working with a colleague who is relatively experienced. We made a large delta robot arm and plan to use it as a pick and place system coupled with a vision system to move items from a conveyor belt. We setup the arm in linuxcnc and can move it using gcode. The motion control and IK work fine.

I managed to use the python MDI interface to send gcode to the arm. This works OK but there is a small delay when sending the commands and I don't know how I would approach timing and synchronizing the movements through gcode as you don't really know when exactly they're going to be executed.
Ideally, I would somehow inject my coordinates and speeds into the motion controller using HAL but after digging quite a bit I didn't find an obvious way to do that.

What is the best way to do this and how would you approach this?
Thanks

Ok I tried to get the info about the last core with this message.
lscpu -p | tac | awk -F
As stated I am very green with LinuxCNC so maybe the command or location in the terminal may be wrong.  But the info was not gathered to make changes to the Gurb file. Attached screen shot of terminal results.  I did try with --F and -f and -F,    
Help.

Those errors look like you selected a 5I25+7I76 configuration in pncconf
(the error is because the 7I76 configuration enables 5 stepgens
 and you only have 4 in the 7I77+7I78 firmware)

As tommylight said, you should chose 5I25+7I77 in pncconf.

Then get that part working before tackling the 7I78 part

Wow that was fast! Looks great! 
Let me know where it is at on git and I'll test the operation/workflow.
