Problems keep Z0
-
I have tried everything. I explain the problem again.
I make several continuous impressions (Several Processes), process 1, make home Z0 perfect and load the mesh, but from process 2, 3, 4, ...., some pieces, do not stick to the bed. It seems that Home Z0 does not do well again, because it does not load the mesh.
-
your mesh looks like a sagging x axis. Maybe increase the sturdyness.
-
It is the bed that is so folded, but it is assumed that the mesh, should solve the printing problems

@juanmena said in Problems keep Z0:
M98 P "/ macros / Iniciar Impresion"
where in the g code does it put that?
if its before a G30 then that will undo the mesh bed leveling.

which one is it?
just use G29 S1
check if your macro are actually working.
while printing issue a M122
and look for
Bed compensation in use: mesh -
The mesh charges it well and I have checked it with M122 and it puts mesh. Loading through the macro:
; M98 P "/ macros / Start Printing"; Load Mesh parameters

G29 S1The problem is when the second process begins on another side of the bed, it seems that it does not recognize the Z0 well, although the mesh is still well loaded, but it prints in the air and I am bored looking for the problem
-
ok from your description i though the mesh bed leveling was not applied.
if after the bed leveling the nozzle does not touch the bed in some areas, that could be due to other factors.
wrong probe offset.
carriage tilt
structural problems (which from the mesh bed leveling image it does really look like you have sagging of the x carriage)can you rotate your bed by 90 degrees. to verify it is really your bed?
-
@veti I have turned the bed, and indeed, the bed is bent. You can see that it has the same curve in the other direction.
