Hello Hakan and thank you for all your work.
If I want to create a small PCB in order to add encoders, compatible with LinuxCNC, which version of your project would you advise in order to modify it?

Thanks

I am using hal only with a mesa card to control a monarch lathe spindle. (so encoder, 2 analog drives and some i/o)



Works great.

Software is fine, but is seems like such a shame to use software rendering when you have a good GPU.

Are the proprietary NVIDIA drivers an option?

Please post output of glxgears -info.

glxgears -info usually prints out the actual name of your GPU, not just "NV134"; weird.
Though though the fact that glxgears works perfectly whilst QTvcp crashes is even weirder.

Module ec_master not found in directory /lib/modules/6.1.0-25-rt-amd64

Category: Installing LinuxCNC

I solved this on my Zorin machine by:
1. copying the ec_master.ko module from /lib/modules/(uname -r)/ethercat/master/ into /lib/modules/(uname -r)/kernel/drivers/ethercat
2. returning to the install folder
3. running make clean followed by sudo depmod -a
Hope this helps.

I have 2 PCIe AMD GPUs that I have no use for (too old for 3D stuff becaue AMD only provides support for like 3 years, plus I don't use PCs).

I wish we could trade GPUs.

AMD/ATI stuff works well on Linux because the drivers are in the kernel, though OpenCL is patchy.

NVIDIA GPUs work great on Linux for headless compute, but not always for rendering stuff.

Im looking into this as well, is there a clear cut way of running/interfacing HAL with a custom software?

I guess the real question is how to separate HAL from linuxcnc.

Thanks a lot, i already find this kind of topic but never found the right one. i will read and try it.

I have tried to change the configuration on the hal file using mux4 etc like this, but my stepper motor still doesn't move, maybe because it doesn't have the  stepgen.02.position-cmd parts. But i think it will be much easier with extra joint configuration.

Have a look at 'extra joints'. sim configs can be found in 'configs/sim/axis/extrajoints.
github.com/LinuxCNC/linuxcnc/tree/master...sim/axis/extrajoints

There is also some information here:

I see these two lines
[35409.201765] EtherCAT WARNING 0: 12 datagrams TIMED OUT!
[35409.331702] EtherCAT WARNING 0-1: Other mailbox protocol response for eoe0s1.
The first one with datagrams TIMED OUT is usually due to network adapter perfomance.
If you have a Realtek network adapter, install the realtek dkms linux drivers.
12 datagrams timed out isn't too bad and it should still work.

The second line indicates your drive supports EoE, Ethernet over EtherCat.
Unfortunately, linuxcnc-ethercat doesn't support that and people have all kinds
of problem to get such servos going.
The most straight-forward way is to download the IgH Ethertcat master and build it
with the flag --disable-eoe.
There is another way - read out the eeprom content of the drive, modify two bits,
and write back. forum.linuxcnc.org/ethercat/55806-long-i...660n?start=20#337450

Move stepper motor only with push button

Category: HAL

I’m working on a CNC lathe project using mesa card 7i98 where I want to add an extra stepper motor to control the chuck lock/unlock mechanism. The goal is to operate this lock only using a push button, completely independent from any G-code commands. This is to prevent accidents in case there's an error in a G-code file that could unintentionally move the chuck lock.I’ve already managed to configure the stepper so it can be moved using a push button, but the issue is that in my current configuration the motor is still connected to joint.2 and axis.a. I’m worried that if something goes wrong in the G-code, the machine could send motion commands to this stepper as if it were a normal axis, which might release the chuck during machining.What I want is a clean way to configure this stepper as a completely independent device, not tied to any axis or joint used by the motion planner, so it will only respond to the push button input.Has anyone implemented something similar or knows the proper way to configure this in LinuxCNC?

Maybe this is documented already somewhere and I just missed it. The key to all of this is this magical argument in the slave tag
configPdos="true"
This actually does alot of what I described above, however, it works in the XML for "other" reasons. If you look at the dmesg log with "ethercat debug 1" you can see exactly what its doing. The XML is still incorrect. To truly use the configPdos="true" properly you have to use the variable mapped PDO's. The reason the XML "works" is because it sets the PDO assignment register to the address listed in the <PDO idx>, however you will get a bunch of errors because it will try to map the PDO's to read only registers. And you don't truly get a variable assigned PDO, you only get what is in the fixed PDO in the registers selected. So it could be intentional, but if you are going to use it, might as well use the variable mapped PDO so you can pick and choose exactly what PDO's you want. However, I think there is a caveat to this, variable PDO mapping is only available in Firmware version > 2.1. So this could be the "lazy mans" way of setting the Fixed PDO's for SM 2&3.
