Different jerk values for pause?
-
Hi everyone,
I've been doing a lot of tweaking of a new machine which requires very fast pausing during long movements.
When setting up I found my ideal X,Y jerk values to be around 10. With these values I found that the pausing was not as immediate as I would like (despite setting a very fine segmentation).
After seeing this in the docs:
When RRF receives M25 it will look for a move in the current queue after which it can stop without violating the configured jerk limits.
I tweaked the X,Y jerk up to around 90 which gave me the almost instantaneous pausing that I was happy with. However when I went back to doing some moves with corners the machine was overly jerky (head has a large mass).
Would it be possible in a future firmware to set different jerk values for pause and normal movement, as I don't care if the machine jerks to a halt, but I do care if it jerks around a corner?
Thanks and let me know if anyone can think of a workaround using the current firmware.
Cheers,

@tristanryerparke we have plans to implement feed hold in a future version of RRF, and that would also facilitate pausing quickly regardless of the jerk. It's pencilled in for release 3.5 but as 3.5 is already late it may have to wait for 3.6.
