tried here, it works with the original trajetory planer on the rip install, when i change to tpmode=scurve i need to desable homing on the gantry axis and i can do jog movements but when running gcode the machine seens to be stoped but it is runing with an extremaly low aceleration, near 1 minut to move 1mm

net estop-loopback => hm2_7i97.0.ssr.00.out-00

should probably be:
net estop-loopout => hm2_7i97.0.ssr.00.out-00
 

- Solved -

There is a startup sequence in control word,
set bit number 1 2, 0 to 1
then if you set bit 3, drive goes to enabled state,

Thanks a lot

Great! Don't worry about the cia402.comp as it needs work to work with the homecomp features. In fact it needs rewriting  from scratch I think...

Thank you mr Hakan,
I added them,

This pretty clear, I would have thought.

To one well versed in building distributions, yes, but not necessarily to one who has only used distributions! Not until now, anyway

I was but at that point, didn't realise the significance of the kernel being sourced from a different place to the base distribution.

It does now load on boot.

Thank you.

Hi Tia,

It seems the .img won't work ok.

Today i tried the scurve + ethercat on a desktop pc and it runned ok.
It's using a EK1100 + 3x EL2124 on a stepgen component.
Jog speed was around 15000 mm/min wich i find not optimal, but ok for ethercat.

The config:
1x linuxcnc iso from : linuxcnc.org/downloads/
1x ethercat installation : ethercat install
1x linuxcnc + scurve, using makefile build system : codeberg.org/skynet/linuxcnc
1x linuxcnc-ethercat, codeberg.org/skynet/linuxcnc-ethercat.git

Running the config : config link

Now i can not try the cia-402 component myself as i dont have the hardware for it.
But maybe you are able to try this again.

I guess the culprit is that chip, I already tried to redo the soldering, but it was no use.
I have the first unusable board with two of those chips, I'll see what I can do, I've never unsoldered/soldered chips like that.
thanks

Then there is some other config error.
The drive should go to OP if you use cia402 or not. cia402 works in ethercat OP only, not in PREOP or INIT or any other,
so it should go to OP regardless if you use cia402 or not.
Can you post your hal file when using cia402?

Thank you
it's not a configuration problem
I tried the procedure you described, but nothing changes

 

XYB works, ZC dir doesn't work, A doesn't work
it's a hardware problem.
Thanks

I have also some backlash to geartrain..
This will be problem for rigid tapping when tap goes backwards ?
If yes then must mount also encoder on spindle shaft..

I think that you could theoretically do this using a separate HAL component that monitors the joint positions and knows the tool length.
There are reasonably well-defined algorithms for "is this point inside this volume", so you would need to define your no-go volume (which sounds like it rotates...) and calculate the tool-tip position using the values from various HAL pins.

You could even, possibly, define a "skin" round the outside in which the adaprive feed ramps to zero, for a more easily-recovered stop.

For example the code here can tell whether a point is inside an STL file, and an STL file is easily generated by any 3D CAD package:
github.com/marmakoide/inside-3d-mesh

with my current configuration I can make the drive ethercat OP state ,
and Ican track absolute encoder values,

with cia402, drive not goes to ethercat OP state, stay preop

It is obviously a cia402 drive.
Download and install the cia402 component.
See an example config here
