Thanks guys, I fix it.

@phaedrux Looks good, but what about the four points in corners? I started printing yesterday and first layer looks good. Object was in the center of bed and has diameter 150 mm.

@phaedrux

@phaedrux Level the bed, I mean G29 settings

@fcwilt G32 works fine, but G29 has problem, so mesh.g

@fcwilt In M558 doesn't work

@phaedrux Any simple gcode for leveling? I edit G28 gcode too.

@fcwilt Hello two speeds are where in firmware please?

@fcwilt I send G28 before G29

@fcwilt hello in mesh.g

Hello,

I can´t find any solution for me, can you help me, please?

Warning: the height map has a substantial Z offset. Suggest use Z-probe to establish Z=0 datum, then re-probe the mesh.
4 points probed, min error 0.223, max error 0.401, mean 0.304, deviation 0.070

@petr-k And P≠0

G31 X35 Y-4 Z0 P500 was the problem, I had two parameters P (P0 and P500), now works great

@dc42

sensor connected, not triggered - 3.0V
sensor connected, triggered - 0V
sensor disconnected, not triggered - 0V
sensor disconnected, triggered - 1,5 V

All with diode.

My soldering looks like a second diode

@fcwilt

@fcwilt I try it without diode too, but it was the same, nothing changed.

@fcwilt M558 P5 C"^zprobe.in" H5 F120 T6000

@fcwilt said in NPN sensor problem:

M558 P5 C"^!zprobe.in" H5 F120 T6000

Z probe value 1000, when triggered value is 0

@dc42 pullup did nothing
