Along the lines of ubl...
I have been reading whatever documentation and old threads I can dig up and (due to the age of what I found) I am still a bit confused on ubl.
I am currently using the latest skynet3d firmware which is based on marlin for my anet a8 printers.
Skynet3d has the option to use ubl but it was easier and faster for me to setup bilinear leveling.
I have tested my inductive probe and its deviation is along the lines of 0.002xxx on average.
I recently switched one of my rigs to a bowden/e3dv6 setup and I noticed that the right side of my bed is higher than the left. The bilinear mesh data shows this as well with point (2,2) having a higher positive number than the other points after probing a 3x3 grid. I tried a 9x9 grid at one point.
What I noticed is that the high side of the bed sees the closest point of the nozzle and the low side sees the farthest point. I thought auto leveling was supposed to adjust z up or down to keep the gap the same but it is not happening in this case.
My z offset has been set correctly...after a g28 I send a G0 Z0 and the nozzle (in the center of the bed with bed and extruder heated) is at the proper gap to the bed (0.1mm with a feeler gauge). My mesh data is being activated in gcode prior to the print start with M420 S1.
I was looking at ubl to test but with all the information I have seen about manually editing the mesh it seems counter intuitive to the name "auto level". I like the notion of using g26 to print a test pattern to verify the mesh level data but this option is not available for bilinear leveling.
So I am wondering, what is there about ubl that would make it more desireable over bilinear and how can it be done as automagically as possible?
Thanks for any information.
