not implement AUTO_BED_LEVELING_BILINEAR/AUTO_BED_LEVELING_UBL #6

hello! Sorry for my bad English. I`m use AUTO_BED_LEVELING_BILINEAR function on Sapphire Pro with 3DTouch. firmware 2.0.1

G29 is work: SENDING:M420 V Bilinear Leveling Grid: 0 1 2 3 4 0 +0.014 -0.253 -0.506 -0.717 -0.889 1 +0.059 -0.199 -0.458 -0.693 -0.877 2 +0.078 -0.163 -0.418 -0.659 -0.856 3 +0.079 -0.160 -0.409 -0.638 -0.826 4 +0.088 -0.147 -0.402 -0.626 -0.806 echo:Bed Leveling On echo:Fade Height 10.00

But, this map not implement for move G0/G1 - movements is planar. Z is constant. Does anyone have 3DTouch | BLTouch? i`m try UBL and G29 P1 IS WORKING:

BED_LEVELING_METHOD 4
but only after recompile 2.x.x, not compile firmware version 2.0.1

My config robin_nano35_cfg.txt

strange. Maybe the eeprom error was. On compiled firmware 2.0.1 - AUTO_BED_LEVELING_UBL works ! By the way, why are the firmware 2.0.1 sources not uploaded? there is a have BabyStep in it during printing

This problem has been fixed in the V2.0.2 version, and the source code has also been updated

Thanks for the new version and source code! I tried setting the auto level in version 2.0.2 many times. Now, after calibration, motor Z moves when moving along x and y. But the result of level calibration with the parameter BED_LEVELING_METHOD == AUTO_BED_LEVELING_BILINEAR is unpredictable. Twice I drove a nozzle into the table (I printed the first slow test with the G30 command and gives an error of 0.05-0.1mm at the calibration points. I perform the auto level with this sequence in the gcode file: G28; G0 Z5 f3000; G29 J; G29;  and print test rectangles in layers from 0.2-0.15-0.1mm.

Returned to using the mode:  BED_LEVELING_METHOD == AUTO_BED_LEVELING_UBL in the same firmware 2.0.2. I use the code: G28; Home G0 Z5 F3000; ++ up 5mm for move G29 P0; UBL reset G29 P1; UBL autolevel G29 A; UBL autolevel Activate M420 S1; autolevel ON After that, the first 0.1mm layer prints perfectly. re-checking with the G30 gives an error of not more than 0.03mm. The main drawback of this mode is the incorrect interpolation beyond the borders where BLTouch cannot reach - for me this is a wide 40mm band
