Hi Tia,

when i change to tpmode=scurve
It is : tpmod_scurve

And check if you use values for the trajectory :  vel + acc.
[/code]

I just isnstalled debian 13 on the desktop pc and installed the same software, but the ethercat-master from the codeberg repo.
It also runs ok. So that's a good sign.


 

Today I ran some more tests. I can now reproduce the issue described in the other thread with 100% consistency. I noticed that when the Z-axis is moving, G96  doesn't seem to be working. I recorded a video showing that the spindle speed doesn't change at all during the movement.



PS. I think there might be something wrong with the HAL configuration. I just noticed that when starting LinuxCNC, I need to go into the calibration settings and re-save the PID values for the spindle (I enter test). If I don’t do that, the PID control is soft– under higher spindle load, it triggers a hold  .Also, if I leave LinuxCNC running idle (without running a program) for about an hour, and then start program execution again, the axis movement speed during a G1 command is once again higher than what was set.

That would be lovely - the CM5 has one but then you need a carrier board and I don't know if the LinuxCNC image would run on the CM5/eMMC? With the right carrier board would be perfect though...

Dunn why RPi doesn't add a connector for an external antenna.

Just for completeness and to save anyone having to mess around with compiling kernel modules, here is what looks like a fairly comprehensive (at least until 6.13) list of in-kernel USB WiFi devices: github.com/morrownr/USB-WiFi/blob/main/h...in-kernel_drivers.md

Discovered it a little late but I think only one has an RP-SMA connection.

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.
