Trouble to find the Z axis home position for every print
It always struggles at beginning of the print.
Try to find the z axis home position and keeps trying.
the bed moves up and down and seems got lost.
I have to try few times before it can continue to finish the real print job.
even I observed that the bed touches nozzle few times and it got lost after and keep moving the bed up and down until fails.
I have firmware version 6.3.2+10364
Thanks,
James

Hi, I have the same problem as you, did you manage to find a solution?

Have you tried lubricating the lead screws?

Not yet,
My guess now is that I may have a bad loadcell.
RE: Trouble to find the Z axis home position for every print
I'll try right away,
RE: Trouble to find the Z axis home position for every print
nothing to do, I have already replaced the load cell with the one from the mk4, then I replaced the loveboard with the one from the mk4 but the result is always the same.

It must be a firmware bug.
I observed few times that the bed is in the middle, and moving up and down try to find the nozzle.
Does Core One has stop switch on z axis to get home position right on first try?
My 10 years old 3D printer can do it on first try. I can't believe this expansive model can not do the simple thing right.
RE:
It seems that the problem has been solved in my case by replacing this in the G code start.
M109 R{((filament_notes[0]=~/.*HT_MBL10.*/) ? (first_layer_temperature[0] - 10) : (filament_type[0] == "PC" or filament_type[0] == "PA") ? (first_layer_temperature[0] - 25) : (filament_type[0] == "FLEX") ? 210 : 170)} ; wait for temp
With
M104 S100
let me know if it solves for you too
