3.5 beta 4 - stutter on slow diagonal

IndeX4D

hello all together,
since upgrading to beta 4 I have some stutter when printing lower speeds (less then 90 mm/s).
I have a double y axis.

But also in open loop both axes made weird sounds.

In beta 3.5 was everything fine.

May somebody else has the same?

@IndeX4D have you retuned? there have been some changes in that area

IndeX4D

@jay_s_uk
ok I´ll try it.

open loop before homing sounds horrible with mheavy vibrations, but this is not that important.

thanks

IndeX4D

@jay_s_uk
thank you

New Tuning parameter works.

@IndeX4D said in 3.5 beta 4 - stutter on slow diagonal:

open loop before homing sounds horrible with mheavy vibrations, but this is not that important.

You may be able to resolve that by reducing the motor current temporarily during homing. See the M913 command.

i get stutter on the new 3.5 beta4 when manually jogging in the X direction only. it is not repeatable and only happens randomly. Each time i am jogging 50mm increments, and it seems the stutter is 25mm-25mm to reach the 50mm. for example i will jog 4 times in the same direction, and the last jog is two 25mm jogs rapidly instead of one 50mm jog.

@RogerPodacter Best to start a new thread as this one is marked solved.
