Closed loop - encoder/position not updating while moving was created by backyardengineer
Closed loop - encoder/position not updating while moving
Category: HAL
Hello,
i am currently stuck implementing a direct closed loop (2 axis lathe, parallel port, stepper motor, linear scale for closed loop).
The problem is: I do get the right position feedback, when moving manually (DRO display is correct) and i can see the correct encoder positions (in Hal-Scope: encoder.0.position). However, as soon as i try to move the axis, it starts to move and errors out with following error. If i look in the hal-scope, the "encoder.0.position" does not move one bit during the move (stepper is moving).
--> Why does read out the position while idling but not while moving ?
Thanks

When I tested the above code, it would change the text, but the color stayed black (no color changes)

Try with synctorefclock false, and see if your reset counter also counts up or not

Note that LinuxCNC only supports Python3/Gtk3 from version 2.9.x so if you are using any custom python or glade code you would have to port those files to python3/gtk3.
In my opinion you'd be better off getting a second ssd and do a fresh install of 2.9.8 on that. Once you get that installed port your config files from the current drive to the new one.

Did you say you had changing values on pll-reset-count? That one should stay on 1, not increase.
Can you perhaps record pll-err in halscope and show?

From google:
Debian 10 "Buster" reached its official End of Life (EOL) and concluded Long Term Support (LTS) on
June 30, 2024. After this date, Debian no longer provides official security updates or bug fixes, making systems vulnerable.
Try this at your own risk.

Personally, i will never understand why risk a perfectly working system for absolutely no reason, IF there is nothing you absolutely need/require. I have machines with Ubuntu 8.04 still in daily use. No internet, usually, so...

Is your
sync0Shift="0"
???
You should set sync0Shift to 250000 or 500000
sync0Shift to 0 is not correct, as per my understanding of the ethercat DC specifications.

So I checked and my lathe is running Lcnc 2.8.2 on Debian Buster, with RT 4.19.
Since Buster is still okay per the updating instructions, I thought Id try an update.
I added the repository.
but get errors
...
I attached the full error log.
Does this mean Buster can no longer be updated?
Cheers,
Mark

Bumping an old thread. Does anyone know if the
g37 & g37.x macros from Pathpilot
can be used in LinuxCNC and if the code is available?
For those with large, conventional autochangers and fixed tool holders running production parts, I can see how this workflow seems forgien. However,for everyone using a manual change spindle and adjustable tool holders/collets, probing a tool length setter after each M6 is common. It is quicker than running a single toolpath per job and reduces the risk of collision due to operator error, i.e forgetting to manually update your WCS Z zero for each tool.
