Z axis issue: wrong movement (layers)

@bot said in Z axis issue: wrong movement (layers):
The user seems to be using pid with the bed but using default parameters
Yeah , it is. I've never tuned the bed because I never use it (At least for now ).
-
@zecchi Sorry about that. If you're not heating the bed that is clearly not a factor.
-
Today I'll try the new z axes. I set up them yesterday. My last chance...
-
And here we go!!
The problem were the two z axis.
Maybe it was due to the elasticity of the belts!!Thanks to all.
-
Congrats on solving the issue.
A question out of curiosity, what did you change in your Z axis?
-
@zecchi
Thank you for sharing.
So you wouldn't recommend short belts for driving the axis?
I was close to modify my HEVO in the same way.
By the way, have you designed the geared axis by yourself?(UTC+1)
-
@Dkos
I've replaced it in this way:
Actually there are other improvements to do (these lead screws are too short ) but for now it's ok
-
All my printer is designed by me.
And yeah , belts are not a good solution for high loads. -
@zecchi Thanks for the info, I also have the same issue as you had (i think), but not as intense as yours and i am running my Z axis with a closed loop belt. I guess i will give the direct a try to see if the issue is going to be completely eliminated for me as well.
Cheers!

So I'm guessing eccentric pulley leading to uneven motion.
