I have an Anet A6, an SN04 sensor for the Z-axis, and Marlin 1.1.x software that has automatic bed leveling enabled.
My question is (looking at the image below): "It seems my bed leveling is not working correctly. What can I do to improve it?"
You can see several things below:
- I tried to use glue to make the first layer adhere better.. works only for small prints;
- the middle part of the print is being done quite okay;
- the outer part are either too low or too high.
I used the following procedure to get my leveling "right":
First I set the z-offset with the M851
command, followed by M500
. Then I performed the bed leveling with G29 T
, followed by M500
. Then I started my print.
Maybe I need more grid points for my bed leveling, even though I have this interpolation method on. Or do I need to check the implementation of the bed leveling, maybe something is just plain wrong in the software.
What is your recommendation?
