Hi,
Still some issus with my Prusa I3 Pro C, but i'm touching the goal!!
problem is simple: the firsts layers (around 10 of a 40 layers objects) are printed very good. Extruded is well positioned, good distance from heating bed, everything is OK. But after few layers, the extruders is more and more touching the printed objet, and it finally make it move... The object move and the print is going to garbage.
I have tryed several things, and modify the printer a little bit:
- i have add the auto bed leveling, with an inductive sensor.
- i have modified the marlin firmware to mait work.
Every print i make, no matter the object (only calibration object for now), it's same results: the 1 to 10 (around) first layers are perfect.
And after,the extruder seams not to get enough height, and begin slowly but surely to touch the object.
Don't know how to solve that...
I tryed to higher to extruder from the bed, but if so, i have bad print quality for firsts layers, cause it's too far from bed.
Thanks for your help, i become crazy!!

You said "make it move",what temp is your heat bed?Did it reach the preset temp?And if the bed's temp is right,i think there may be some installation issues on Z axis...

Re: Object move after few layers
Hi
I have made different test
with bed a 70, 80 or 90
Effect is the same.
But we clearly see that it come from a z axies problem, since, it begin well for the first 5-10 layers, and after it doesn't goes UP enough, so finish by touching the object.
I know it's a Z axies problem, but really don't understand what....

Re: Object move after few layers
lol...
check what? check how?
i have no idea what is the problem except the Z axies.
I have tryed every change i could in the firmware nothing works.
I have 2 options
1) re-calibrate the distance that manage the printer, their must be a problem with distance (exemple; when need to move 1mm, maybe it move 0.9 or something like that) ---> how can i do that?
2) the threaded rod to change, maybe bad quality -> i hope this is not that, cause the printer is new.
Otherwise, don't know what to do, or what it can be
heeelpppp please

Re: Object move after few layers
The second option you can check,i think...
Also,have you tried this setting before?Enabling this option will cause the nozzle to lift up a set distance above the previously printed layer before moving to a new location. When it arrives at its final location, the nozzle will lower back down to prepare for printing.

Re: Object move after few layers
Hi,
Just to tell i solve the problem, if anyone have the same
It came from
#define DEFAULT_AXIS_STEPS_PER_UNIT {78.74,78.74,2560,95} // MXL, Z M8=1.25, MK8
I replace it by
#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,4000,95}

Hi,
How do you ensure the value is that the problem exists?And are you sure the value is right?

Re: Object move after few layers
Hi
Yes it seems correct.
At least, it solve 2 problems i had:
1) a lot of noize when Z axies moves
2) Z axies won't move enough during the printing, so step by step, the was closer to object.
All has been corrected by changing to {x,x,4000,x}
For all, i used this calculator
