Hi all,

printer : A10 with Marlin 2.0
sensor : Touch-Mi (https://www.hotends.fr/fr/home/64-capte ... ch-mi.html https://hotends.dozuki.com/Wiki/Capteur_TouchMI)

In marlin I using AUTO_BED_LEVELING_LINEAR option with a 5x5 mesh

In pronterface I send G28 + G29 ... and my printer execute a good probing with mesh 5 x 5

after I send a M500 ... but when I send a M420 V I have a 3x3 meshing ...

Bed Level Correction Matrix:
+1.000000 +0.000000 -0.000282
+0.000000 +1.000000 +0.000992
+0.000282 -0.000992 +1.000000
echo:Bed Leveling OFF

And at the end of my starting gcode I send a M501, G28, M420 S1 (to activate bed leveling)

Can you help me to have a good meshing (5x5) ?

Thanks,
Hatoupix


note :

If I reset the matrix (M502) I have :
+1.000000 +0.000000 +0.000000
+0.000000 +1.000000 +0.000000
+0.000000 -0.000000 +1.000000
