help with ethercat and omron drives

Category: EtherCAT

Yeah, later today I'm gonna reconnect the omron software and see what's up. its possible they got wiped somehow, but seems unlikely.

I don't really thing there's anything on the linuxcnc side that could be at fault though, its not even commanding a movement yet, just enabling the drives.

Yes, I am using interpolated position (which is very precise with the hardware generated "encoder' signals)

You are right. There is no pid control loop for the axis in ini or hal.
It's all in the servo drive.

It can help to lower P in the servo drive for the noise. But you said you tuned them, so

W5100S-EVB-PICO stepgenerator and encoder driver

Category: Driver Boards

!UPDATE!
the default settings in the code makes the:
4 stepgenerator (up to 512 Khz in 1ms servo thread)
2 quadrature encoder counter (example: 1 for spindle encoder 1 for MPG)
3 digital outputs
1 pwm output (from 1.9Khz - 1Mhz varies from 7bit to 16bit resolution, depends of the frequency)
4 digital inputs

docs how to change this is in progress

Thanks for your fast reply.
That's the output of "gpioinfo", looks ok for me:

Hi Chris,
how to install this widget? Only copy the file indicatorMixIn.py to /usr/lib/python3/dist-packages/qtvcp/widgets ? Can it then be used with Qt Designer?

Are you using position-interpolated with your 8-count encoder?
Is there any quantisation of the error you see?
I haven't looked at the spindle synch code, but if it tries to "start early" before the index then possibly a low-count encoder will make that more difficult.

Yes, you are right, there is no error on multiple constant speed
paths, I had neglected to 0 the q parameter when testing.
This is because the return path has a constant x distance from
the cutting path.

You get the error if you change the spindle speed (or motion constraints)

Basically I would think the the z motion should be strictly geared to
the spindle (+- any deliberate offsets like "q") just like a mechanical
lathe.

Why does it seem like everyone here is Australian?

Category: Off Topic and Test Posts

When I first started with LinuxCNC the vast majority of the developers were in the USA. (with the exception of a Romanian)
There has definitely been a shift to Europe and Australia, though many of the folk here are still in the USA.
FWIW I am in the UK, because my antecedents managed to avoid being transported.

I have done some work on psng to adapt it for Gtk3 / Python3 on Debian 12+
However, on my test machines, whilst it loads without errors, there are no graphics visible in the embedded tabs.
