Build master fails

Probably due to different Python requirements it wont worn on Debian 10, but should work on Debian 12.
Try compiling the 2.9 branch, that should still work on Debian 10.

Hello
I have not been working on linuxcnc for a while now (2.10.0-pre0-3309-gfd6a133f8b), but this week, after a git pull, I can't build anymore :
....
Done reading realtime dependencies
Compiling hal/components/panelui.c

I'm on Debian 10.13 .
sudo apt update and sudo apt upgrade done.
dpkg-checkbuilddeps return si empty.

Any ideas ?

Touch Screen recognized in Settings | Mouse and Touchpad but touches do nothing

Category: General LinuxCNC Questions

I'm trying out a new touchscreen with LinuxCNC 2.91 on RaspberryPi today. 

The Touch Screen is recognized in Settings | Mouse and Touchpad; two instances of wch.cn TouchScreen, however touching the screen has no effect either on the desktop or from within Axis.

Do I need to enable a driver, or do something special to get this to work?
The keyboard, mouse etc are also recognized and they both seem to work just fine.

scorbot-er-3

Category: Installing LinuxCNC

Please help, the Scorbot-ER-3 grippers are ran thru a gui "pop-up" on the main LinuxCNC screen, which has to be operated by the mouse clicking and dragging. Through the hal_meter I found the following:

Hal Meter
scorbot-er-3.joint7.limit-sw          [FALSE]
scorbot-er-3.joint7.motor-max-vel    [9]
scorbot-er-3.joint7.motor-pos-cmd  [-200 to 200]
scorbot-er-3.joint7.scale                   [1]

The key here is 200 is gripper closed and -200 is gripper full open. 0 is gripper 1/2 closed.

I would like to use the jogger mode and Logitech dual action F310 pendant buttons;

input.0.btn-pinkie (top right trigger)
input.0.btn-top2 (top left trigger)

To open and close the gripper. In addition would like to use M code for the same pursose. Currently the gripper is ran with xml files. The gripper is #joint 7 in the scorbot-er-3.ini file. Please let me know what files you need to see to help me. Thank you all again

Wiring Mesa 7i95t inputs in parallel with DRO

Category: Basic Configuration

You can use external encoder feedback on step/dir systems
_BUT_

1. It really only makes sense with linear encoders

2. The tuning is much different (you must use a much lower P term because of the phase delays
between step and actual motion in the system)

3. You need to have the encoder scaling and direction correct

4. Any backlash will cause pain and suffering

Oh my.
I go in expecting complicated because that's what I'm reading about and get TTL. <bangs head>
I now have numbers appearing in
  hm2_7i95.0.encoder.0?,count and .position
now to figure out what to do with them.
At the moment nothing goes beyond the inputs but...
Could I make it fine tune my position?
Is that realistic or will I just get the steppers oscillating wildly between the ends of my screw slop?

thanks guys

2GB is not enough, 4GB is usable but 8GB are required for anything above the Wheezy version of LinuxCNC.
Still bad latency but i do not see the link being dropped, so this might just work.
First, enter the PC BIOS and disable hyperthreading, TPM, AMT, turbo, any power saving features, virtualisation, etc, then do another test.

You are welcomed, always.
Did you read the servo tuning and wiring on this forum? Can not recal if i did point to that, but that is a must for such retrofits.
forum.linuxcnc.org/10-advanced-configura...ning-detailed-how-to
And while you are at it, please let me know if there is something that can be explained better or anything to add or remove.
Also, no skipping steps when wiring stuff, one by one step at a time. :)

Those are terribly horrible results ! :)
Was latency better before installing the DKMS drivers? Why and by who were you told to install DKMS?
If i recall correctly you had dropped link to Mesa board, but they were not from network issues, they were from huge latency issues, is this that topic?
Did you disable stuff in BIOS?
How much memory does the PC have?

>Not quite understanding your meanings. The PC is of 2Gb memory.
>Now I replace the computer with the old hard drive which stored old version Linuxcnc 2.8.4, for perserving purpose, no Linux undates/upgrades and network drive update on it. The latency test runs, attached are two pictures and the last picture shows  screen that the axis run without much problems

Servo drive or some kind of problem

Category: HAL

Good news…. So the book for the drivers benb posted isn’t like mine but close enough I kept reading it to see how those drives work. He also mentioned the digital inputs.
So I read back to make sure I didn’t misread what I read about external switches (essentially left/right drive disable).
Turns out I misinterpreted it or whatever but the books says something like this
“If no external interlocks are required wire them to signal common”.
So since I was on the bench I jumped each of them to common on the drive board.
Next section I read how the L/R disable works and it turns out the switches are switched to common to disable the drive in one direction. DOH!

Went straight to the box this am. Pulled my jumpers enabled the drive and I have motion in both directions.

And Tommy you are def correct. I listened this time and only used the 1.5v. Those drives move pretty good with that.


Anyway. Thanks again for everyone’s help. On to the tuning tutorial I suppose

Nun habe ich die 7i92 direkt in die 7i76 gesteckt und schau an, der Encoder 04 funktioniert jetzt auch auf der 7i76.
Da habe ich wohl beim Crimpen nicht sauber genug gearbeitet

So wie es jetzt ist, bleibt es auch.
Danke nochmals für eure Hilfe

Now I have plugged the 7i92 directly into the 7i76 and look, the encoder 04 now also works on the 7i76.
I must not have done a clean enough job when crimping

It will stay as it is now.
Thanks again for your help
