Z weird sound and sobbing movement
-
Hi,
I have start to have a strange issue on the Z motor.
It has start to do this weird sound and start to sobbing when i changed the confing.g for increase the motor current, X, Y, E0 from 1000mA to 1500mA and the Z motor from 600mA to 1000mA because all the nema17 have 2A rated current.
When i try to move the Z+ or Z- from the web interface it goes only down (it rotates in the same direction).
This is the confing.g with the increased the motor current:; v6 ; Increased motor current.

I have uploaded the old version and it has continued do it.
I have moved the board to look if there was some black zone but i don't see nothing.
I have tried again but it has stop to do it as you can see in the video (i have sewed the two video with and without the weird suond).
I think it's the Z cables but why both motor do it and not just one?
What do you think? -
That could either mean that the leadscrew is binding, or that only one phase of the Z motor is getting energised. So with power off, check that the leadscrews can rotate freely. Then check for continuity of both motor phases of both motors.
I don't see as M584 command in your config.g so I presume you have the 2 Z motors plugged into the 2 Z motor connectors. Those connectors are wires in series. So a bad connection or cable will affect both motors.

Ok thank you, each motor can freely rotate so i will check the cable and the motor phase with a multimeter, i hope to find something so i can be sure to have solved it.
Yes there are 2 Z motor connected in series.
For now thank you for the help

For now it seam it works. I have soldered the cable extension of one z motor (before it used a dupont connector), the other is near the duet so it hasn't an extension cable.
