G29 in start code doesn't seem to activate Mesh Bed Leveling January 02, 2018 05:26AM |
Hello!
I have manually probed my bed and come to this Mesh Bed Leveling grid.
0 1 2 3 4
0 -1.20000 -1.20000 -1.10000 -1.20000 -1.00000
1 -1.40000 -1.40000 -1.60000 -1.60000 -1.30000
2 -1.40000 -1.70000 -1.80000 -1.80000 -1.70000
3 -1.70000 -1.90000 -1.90000 -1.70000 -1.20000
I store it in EEPROM with M500
In Marlin 1.1.7 I have done the following in Configuration.h
When I perform a G26(a test grid pattern) everything works fine. The Z axis motors rotate during print. That leads me to believe that my Start Code in Cura does not active the Mesh Bed Leveling system.
When I print an object THE Z-AXIS MOTORS DOES NOT MOVE. They just stand still. What could be the cause of this?
My start code in Cura:
The Gcode in the file that Cura exports:
