2. When the clamps are release and the scale is plugged in and the NC- ready is on its almost as if the mesa card sends out a voltage causing the motor to “bump” which causes a joint error. If I unplug the scale and still leave the clamps off the machine runs fine and the table is steady doesn’t drift. 

If this is a analog system and you prevent motion, Normally you would need to disable the PID
feedback when locked (especially if there is any I term)  Otherwise a large output can develop
as the PID "fights" against the apparent resistance to motion.

Thanks
Pico is on my watchlist.
Unfortunately they do seem to have any dealers in EU.

Gib mal im Terminal ein: lsb_release -ic
Was wird ausgegeben?

Thanks
Problem is availability
Welectron do not sell mesa products any longer
Eusurplus is very limited in stock so I fear they are tapping out of mesa as well.
If it’s not sold within EU we cannot use them as suppliers

Hi all. I’ve converted my maho 700 over to Linuxcnc using a lot of information from Mark (rotary smp). I need some advice or guidance.  So all 3 axis are working and I’ve managed to figure out and get the PID tuning running smoothly. At 1000/mm.s 
im struggling with the A axis which uses a Heidenheim scale. 
1. What scale settings do I give it or how do I workout the scale value of the a axis. 
2. When the clamps are release and the scale is plugged in and the NC- ready is on its almost as if the mesa card sends out a voltage causing the motor to “bump” which causes a joint error. If I unplug the scale and still leave the clamps off the machine runs fine and the table is steady doesn’t drift. 

3. What or how can I get the spindle to be steady? Again of the plug is unplugged from the mesa card the spindle doesn’t “spin” but when plugged in it moves slowly like maybe .5 of a rpm sort of a drift. 

4. Are you somehow feeding a Tacho signal to the mesa card so it can control RPM? Or are you just basing it off the calculation? And how do you get more range so I can run it from 0-6000 rpm. 

5. Might be a silly question this is really a hobby for me. But what is a max MM/S for these machines? Trying to get the max set but don’t want to cause any damage. 


I haven’t worked on the gearbox settings yet just want to figure out the axis first.

Moin an alle

Ich habe soeben meinen Rechner gestartet und alle Symbole auf dem Desktop sind verschwunden. Ich kann auch keine neuen Verknüpfungen platzieren und die rechte Maustaste reagiert ebenfalls nicht. 
Auf jeder anderen Stelle öffnet sich das RMB Menü.

Was ist hier passiert? Kennt jemand das Problem?
Ich habe Linuxcnc 2.9.2 installiert 

Hi,

I have an old computer (pre 2010), 2G ram.  LinuxCNC 2.9.4 runs on it, but I cannot get the jitter down. I have tried a lot of suggestions on this forum (bios settings, deactivating unused hardware etc.). I think the preempt-rt kernel would not work with this computer.

I want to use it for a 4 axis wood router, no fancy peripherals (keyboard and mouse control). What RTAI version of LinuxCNC is lightweight and still has a user friendly interface. I have not tried any of them, I want to ask here first.

Thanks 

It would be great to create a complete, fully open, standardized, and comprehensive solution for LinuxCNC, with open schematics, boards, and enclosures.
If I find the resources to complete the main boards, I will make the completed boards and enclosures, along with the ported firmware source code, publicly available.
Suggestions, advice, and criticism are also welcome.

Far more advice than I could give.

lspci will only probe devices on the pci\pcie bus.
The OP is correct the USB device ids are defined in the header file.
Maybe if the OP raised an issue on the GitHub page he would have direct access to the Devs.
Unfortunately the only thing I can think of is to follow the instructions given in the docs and build Linuxcnc from source as a RIP and see how things go.

Wireless stuff will make the latency of your whole setup worse, though perhaps that's not an issue for you.

Perhaps it's mislabled; would not be the first time.

Is that lspci output?

Estoy queriendo comprar los siguientes equipos:
7i97T (Este es el que no está disponible en Mesanet)
7i84U
7i74
7I73

Why does everyone go to ChatGPT for help?

ChatGPT is kinda stupid and makes errors sometimes.

Though it can be helpful, I admit.

Why do you have an XYZ config if you only have 2 motor drivers?

Create a new config with PNCConf and then try twaeking it with PNCConf, editing the files manually is great,but it's easy to accidentally break the whole thing.

With PNCConf, you can safely edit stuff withing the guided prompts of the GUI.

I recommend you use AXIS as your GUI, and Ipresume you already are.

Pico Systems has the PPMC, a set of boards to read encoders, drive +-10V velocity servo drives and handle digital I/O. It is fully supported by LinuxCNC. Take a look at: picosystems.store/product-category/analog-servo-interface-ppmc/

You would need :
Mesa 7i96S
Mesa 7i83 for analog out
Mesa 7i85 or 7i85S for encoder feedback
or just a single Mesa 7i97T for everything
