Clarifying the Rot-point values was created by akg1904

Clarifying the Rot-point values

Category: Advanced Configuration

Hi everybody,

I have a small doubt which I hope you all can clarify.

For my z-rot-point calibration,
In my case I think the z-rot point is the distance between z-machine-zero position to the primary rotary axis pivot point (in my case A-axis pivot point) is the z-rot-point value i.e.as shown in screenshot 1: The vector from the origin of the machine coordinate system to point A on the first rotation axis of the table is set as the rotary table position in the machine coordinate system.

Similarly for z-offset in screenshot 2: When the rotation axes for controlling the table are all at 0 degrees, the vector from point A to point B on the second rotation axis of the table is set as the intersection offset vector in the machine coordinate system.

if tell me whether what I have done is correct or not.
Because I went through many threads in the forum but in most cases the rotary point of A-axis is at higher level(in Z-axis term) then the bed(C-axis rotary point) and in my case it is opposite.

Yes it does, if I jog the axis it will change. It doesnt seem to be realted as to how far I jog, the axis just has to move, even 0.1mm

The scurve is present now in linuxcnc master, download from GitHub and build, or use the latest .deb files

With many thanks to Grandixximo and 杨阳 we now have an experimental
S-curve / finite-jerk trajectory planner for testing.

For those that build from source just look for the new v2.10.0-pre1 tag.

Others can download debs from github for the next 90 days:
x86 / bookworm  github.com/LinuxCNC/linuxcnc/actions/run...artifacts/5056097663
x86 / trixie github.com/LinuxCNC/linuxcnc/actions/run...artifacts/5056161668
ARM64 / bookworm github.com/LinuxCNC/linuxcnc/actions/run...artifacts/5056139840
ARM64 / trixie github.com/LinuxCNC/linuxcnc/actions/run...artifacts/5056124080

Make no mistake, this is experimental, there are no guarantees that
these won't break your machines. The first user already hit the hard
stops when homing (too-low max jerk setting)
With the jerk setting it is probably best to start high and reduce, as
infinite jerk is closer to current behavior.

If you run these you are volunteering to be a guinea-pig.

Life has got more complicated. With proper kernel tuning, latency can be better with Debian 13. I am in the process of publishing a second video about this on YouTube. Please refer to my channel. www.youtube.com/@MrRodW
The yet to be published video should be watched before the current one.

If you zero again, does the small values stay the same?

Rhe formatting of the message is screwing it up.

Hi,

I can seem to add the attachments, both less than 1M. Click add image, I can then see it, and press insert.

Qtdragon_hd Zero button not zeroing

Category: General LinuxCNC Questions

 Hi,I have been using linxcnc 2.4 for quite some time and though it would be a good idea to upgrade to the latest qtdragon_hd version. I did a completely fresh install using LinuxCNC 2.9.8
Debian 13 Trixie PREEMPT-RT ISO

I am running a MESA 7176E board for the interface with step and direction ( using Teknic SDSK servos) so effectively open loop. The hal file is copied from my old configuration, so I know it worked. I have added any new items that were needed

I have managed to get everything working pretty much as before and axis all home correclty and the home co-ordinates are all set to 0. If I then jog the table to a position and press Zero on any of the Axis the G54 Cordinates are not zeroed. See attached pictures.

If I set a jog interval like 0.1mm then every jog increments the DRO by the correct amount and the DTI indicates the table move correct.Using the Offsets screen, if I set the G54 offset to the X axis position at shown for the G53 X axis then the G54 will indicate 0. If i then press Zero it goes to some small number.

Does anyone have any ideas ?

I have disabled all EOffsets.Any help great appreciated.

Thanks

Do you _need_ RTAI? What is your latency with preempt-rt?


 

I confess that RT version 2.92 worked well for me, even using LPT with around 25000 latency. However, when I saw Debian 13, I believed I could achieve the same result, but the latency is extremely high, reaching 150 on the same PC that had 25000 latency with Debian 12. That's when I tried RTAI and got these errors. I'm trying to find another PC following Tommylight's advice in an attempt to get some answers.

Yes, this works.

Hovering over your links shows:
github.com/LinuxCNC/linuxcnc/actions/run...artifacts/5056097663
While opening them goes to
github.com/LinuxCNC/linuxcnc/suites/5379...artifacts/5056097663
None work, but removing some tailing does open correct sections for
github.com/LinuxCNC/linuxcnc/actions/runs/20798441121/
where the "artifacts" are listed but not clickable.
Edit
I am not logged in there, i do not have an account.

They all work for me. I will have to try them at work tomorrow as the other-me to maybe see what is going on.
