I changed rods to 8mm from the hardware store (just to check) and installed anti wobble from thingiverse that I mentioned previously. The pattern stays and now it match the new thread pitch. However it looks less noticeable. My heatbed is PID driven, I will recalibrate it.
@Lab_Rat I am not sure what do you mean. I had a thought about playing with steps per mm in firmware, I will check it. Currently it is 80.2 - I will try to change it to integer and see. I am checking everything.
@Lab_Rat You knew it! It’s almost perfect now. Much better than it was.
Thank you all. I will continue to play with it.
