How to know that bed leveling is working?
-
Is there any way to know for sure that the manual bed leveling is working? After doing the 7 point leveling, when I view the Gcode, there is only basic start-end code but nothing regarding bed leveling. I ask this because I am not really getting proper leveled prints. Even after bed leveling when I print, the printer starts printing few mm above the bed. An answer to this mystery will grately be appreciated.

The software bed leveling is applied as the gcode is being streamed to the printer. You can always check that it is working by opening the G-Code Terminal and looking at the commands that are being sent. Typically, G1 commands will not have Z values since the printer does not do a lot of moving up and down. Here is an example.
->N13285 G1 Y-2.48 E729.58*27 [1057.989] <-ok [1058.091] <- [1058.091] ->N13286 M105*41 [1058.161] <-ok T:254.9 /255.0 @200 B:75.0 /75.0 @66 [1058.162] <- [1058.162] ->N13287 G1 Y2.12 E729.733*1 [1058.162] <-ok [1058.193] <- [1058.194] ->N13288 G1 Y6.72 E729.886*13 [1058.194]
However, if software leveling is being applied then all of the G1 commands will have a Z value, since the printer will be constantly moving up and down to compensate for the leveling.
