i got it! i also found it in the ethercat parameters list

now i need to compile the cia402 component. What is the most up to date method to achieve this, are you using the repo of rodw or marco reps?

forum.linuxcnc.org/49-basic-configuratio...eing-behavior#194278

I used the XML file SDOconfig option:

     <!-- Homing Config - 1 - Move to negative limit switch 23 home in place-->
      <sdoConfig idx="6098" subIdx="0">
        <sdoDataRaw data="01 00 00 00"/>
      </sdoConfig>
 

My condolences.

hey guys im trying to test this but i cant find parameter number 6098 to set the homing method to 6 in motion studio, could you please tell me how you configured this parameter?

Hi at all.
I use normally Debian 10 with ethercat and not have problem.
Now stay testing devian 12 (iso by git linuxcnc with uspace) and Procedure CORBETT ethercat installation
at point 3 and point 4.

When start configuration the value the drive and I/O are refreshed after 10 second after start.
On Dmesg have :ETHERCAT WARNING 0-0 SLAVE DID NOT SYNC AFTER 5000 MS
:ETHERCAT WARNING 0-1 SLAVE DID NOT SYNC AFTER 5000 MS
:ETHERCAT WARNING 0-2 SLAVE DID NOT SYNC AFTER 5000 MS
:ETHERCAT WARNING 0-3 SLAVE DID NOT SYNC AFTER 5000 MS
:ETHERCAT WARNING 0-4 SLAVE DID NOT SYNC AFTER 5000 MS
:ETHERCAT WARNING 0-5 SLAVE DID NOT SYNC AFTER 5000 MS


AFTER THIS TIME THE REFRESH THE VALUE ARE FAST AND NORMAL OPERATION, BUT NOT UNDERSTAND WHY AT START THE LCNC HAVE THIS WAIT FOR READ DRIVE VALUE.

THE SAME CONFIGURATION WITH DEBIAN 10 AND ETHERCAT 1.5.2 AND LCNC 2.9.0-PRE0 RUN OK

 

Hi All,

Been using sheetcam and Recently changed my OS to Ubuntu from windows. but linuxcnc isn’t happy with the gcode from the post processor. I copied over all the settings from the windows sheetcam to Linux but I get the below error and can’t fathom how to fix it.

Radius to end of arc differs from radius to start.

Any ideas? Thanks

Hey,
sorry to bother you with this but i can't get this to work and i'm kinda frustrated.
I can't get out of e-stop and get a bad spi payload = 646174

My hardware:
Raspberry Pi 4B
BTT Octopus Pro v1.1 with stm32f446
TMC2209 Drivers with jumpers in SPI mode

I did the wiring acording to the docs and also the installation.
With cutecom i get the output in the attached file for the octopus xyz.hal.
SPI and UART are activated on the Pi and i already did a rewiring of the whole thing.
I'm tottaly new to LinuxCNC so i would really appreciate your help on this.

Thanks! peter

 

I wrote an email on March 24th and haven't heard back, so I just wanted to follow up in case it got caught by your spam filter.

I guess that means positive and negative news for me. For the limit / home switch for Z position I use an inductive sensor and that is mounted in a way, that the tailstock would be detected. The bad news is obviously now, that the home position is dependent on the tailstock position and I will need to make sure, that the tailstock is exactly in the same position every time I perform homing.
Does that sound like a reasonable approach or should there be some absolute location to avoid that dependency ?

It's been a while. Lot's happened in the last almost 2 years. Death of our 35 year old son at the end of 2023 has kind of screwed up my world.

Going through the various postings from back in 2023 I never did see you post a copy of

measure_tool_inch.ngc

If you have the time would you post that please?

Thanks
John

Morning,

I replaced "encoder.00.position" with "stepgen.00.position-fb", which worked fine.

Then I checked the encoder and realized that it was counting in the negative direction when moving in positive coordinates. So, I added a minus sign in front of the stepper count in my .ini.
Now, the axis moves during the first part of the homing process. However, as soon as it hits the home switch for the first time which then tells it to change directions a "following Error" occurs.

Did this machine run the hob with a hydraulic motor for the hob spindle?

I have returned back to 2.9.4 but i will try again master.
In qtdragon_hd i can't find touch plate z axis probing.
This exists in qtdragon but can't find it to hd version.
Is somewhere hidden?

You should have mentioned this is a RPI.

When running the gcode file, set the Max Velocity slider to a lower value, till you do not get the joint following error anymore, then divide that value with 60 and set that value as the MAX_VELOCITY in the ini file.

Also noted the scaling, if you have direct drive belts with GT2 20 tooth belts, the scaling should be 40 or 80 depending on drive microstepping.
