an CIA402 Stepper/Servo as Spindle

You can use this component instead of the standard cia402 component.
github.com/MetalMusings/cia402pv
The drive uses PV (Profile Velocity) mode which is more suitable
for a spindle motor as it has its own speed ramp up and down.

1. Remove 'loadrt matrixkins' from your hal file
2. The KINEMATICS entry of the [KINS] section in your ini file needs to look like this (matrixkins does not support the 'coordinates' parameter):
KINEMATICS=matrixkins

Hi rodw, Im sorry to bother you - the link to your doc in google docs is deleted, can you please tell me where I can find this again actually? I'm again struggling with packet losses.
docs.google.com/document/d/1jeV_4VKzVmOI...diY/edit?usp=sharing is deleted.

Thanks for your efforts!

Colleagues,

I installed the kernel 5.4.290 + the linuxcnc 2.9.4 build that came with it
With the kinematics option KINEMATICS = trivkins coordinates=XXYYZ, everything starts and works.

We have a description here -
linuxcnc.org/docs/devel/html/man/man9/matrixkins.9.html
the example section of hal + ini files is empty.
We also have a description here -
github.com/LinuxCNC/linuxcnc/blob/master...ents/matrixkins.comp
where examples of specifying matrix elements are indicated.
However, there are no examples for hal + ini.
I tried to do the following by analogy with other methods -

HAL -

[KINS]
JOINTS = 5

#2025-11-20 для 2.9.4
#KINEMATICS = trivkins coordinates=XXYYZ
KINEMATICS=matrixkins coordinates=XXYYZ

When you try to launch it, it drops and shows an error -
Debug file information:
./t.hal:16: Can't find module 'matrixkins' in /usr/realtime-5.4.290-rtai-amd64/modules/linuxcnc
1485
Stopping realtime threads
Unloading hal components

for kernel 5.4.254, the situation and error are exactly the same (with corresponding linuxcnc + linuxcnc-dev)

how to fix this?

I note an error in man - there is no [KINS] section in the HAL file, there is such a section in ini, st 149 -

Many problems have been solved by assigning numbers instead of the axis letter (e.g. X) in the .hal file probably generated errors as there were two motors for one axis.

Hi all, i tested again today with a fresh download of  2.9.4 from the main page. And now i am stuck as all the other ones are at, the missing "amdpgu fault". 
Was there a solution on that fault ?, i cant decipher if there was one, on all the other forum posts with that fault. 
ibb.co/G4FrwL3t

If there is not a solution i will try the "mint" Tommylight uploaded :)

It was supposed to work out-of-the-box with the EL1014.
It's a pain when it doesn't.
Seems to be a new version with different PDO mapping.
Can you please give the "ethercat slave -v -p 3" info and I'll
open an issue on github to see if we can distinguish these with the new PDO
mapping from the old ones.

Check "ethercat -p 3 pdos" and "ethercat -p 4 pdos", if they have PDOs at 0x3101 than that's the problem.
Check the link for how to configure those EL1014 with lcec_configgen -typedb=false 
and insert this into ethercat-conf.xml for slave 3 and 4, the EL1014s.
