dittohead Hi. I installed LJ18 sensor to extruder platform, turn on autolevel in firmware, set offsets.Run gcodes:G28 X YG32 S2G28 X YAnd bed going down at 8 mm after calibratingI change z-probe distance settings, but didnt helpOr with numbers I need put to eeprom?Sheme: at 4mm near table sensor triggered
Repetier Why the second G28 X Y? That may cause new changes so at least for testing leave it.Code for leveling is in BedLeveling.cpp in function bool runBedLeveling(int s)As you might see there is no extra Z move programmed. At start it runs activate script and afterwards deactive probe script, which you have defined. That could of course contain z moves. As a Test run G30 at a point where activating z probe is possible. It will return z height and also run start/end script and "normally" ends up at exactly teh same position it started. Also gives you an idea if z probe height in eeprom is set right as it returns a measured z whcih you can compare with e.g. a metal block or feeler gauge.
Repetier No, gcode is ok just second G28 X0 Y0 is unnecessary and might mask the source of the problem.But where the extra move comes form is hard to say remotely, therefor my hints on where to lock what is going on.
Repetier What do M114 before and after G32 return?What is your start and end gcode for z probe in configuration? As I said that would be a good point that it changes.

Repetier You did not home Z before probing. Would at least explain 3.57mm of the drop. Have you tried the same after z homing? You can also use z probe for z homing - in fact you should if you do z min homing. Set homing order with preheat, then you set preheat temperature to 0 and can enter the probing position. That way activating z probe can be done at a position where it is possible.Then try again after z homing. I guess this makes a difference, also not sure what exactly.
dittohead No, just X-Y homing, in some cases when I do Z homing autolevel was abort because "probe triggered before measuring"
Repetier Yes, z probe must not be triggered when z homing starts. There is a parameter to move up before z homing to prevent just this.
dittohead Repetier wroteYes, z probe must not be triggered when z homing starts. There is a parameter to move up before z homing to prevent just this. Z_PROBE_BED_DISTANCE? Or witch one? Repetier No ZHOME_PRE_RAISE is to go up before leveling. dittohead Can't find it in Configuration.h:( MartinH In the config tool.Under 'mechanics' endstop section, choose homing order X Y preheat then Z (this lets you then choose the X Y coords to goto to home Z)Just under the homing order, select pre raise Z axis= always and set pre raise distance to 5 .XY Homing pos. for Z are preset to 99999 99999 change these to the centre of your bed. dittohead Oh, im using 092, found it at 1.0 dittohead Set up pre-raisegot 13:41:51.126: Error:Activating z-probe would lead to forbidden xy position: 60.000000, -55.00 MartinH can you post a link to your current config.h dittohead MartinH wrotecan you post a link to your current config.h https://www.dropbox.com/s/rgsx3xl18p9fff2/Configuration.h?dl=0<br/><br/>I removed z probe offsets, looks like helping Repetier 0.92 is so old and buggy regarding z-probing that I can not really help here.
