could not activate Z probe error

dmkmedia

i finally finished my new printer ready to go but I'm getting an error when bed leveling starts

could not activate Z probe offset due to coordinates constraints result is inaccurate

config as below

Depends on which action it hapens - homing, G32 or G33. The used coordinates are not allowed with active t probe offset so you need to modify that position to lie inside allowed area.

dmkmedia

G21        ;metric values

G90        ;absolute positioning

M82        ;set extruder to absolute mode

M107       ;start with the fan off

G90 ; use absolute coordinates

G28  ;move X/Y to min endstops

G32 S2

M82 ; use absolute distances for extrusion


my bed is X = 275  and Y = 200 so its longest side is the X axis

my config is attached in a zip file

MartinH

#define Z_PROBE_X_OFFSET 35
#define Z_PROBE_Y_OFFSET 5

#define Z_PROBE_X1 20
#define Z_PROBE_Y1 20
#define Z_PROBE_X2 200
#define Z_PROBE_Y2 20
#define Z_PROBE_X3 20
#define Z_PROBE_Y3 190

from your config above, your probe is offset X 35 to the right of the nozzle and Y 5 behind the nozzle.

So your minimum value for probe point X1 will be at least 35(i would go with 45)
X2 can be upto 275 so maybe 265 
The other values should be ok.

sorry for the delay in replying i was waiting for new materials for the new build but i am still getting the error
i have attached the latest config i set it as 45 as told but still the same error

#define Z_PROBE_X_OFFSET 35

#define Z_PROBE_Y_OFFSET 10

#define Z_PROBE_X1 45

#define Z_PROBE_Y1 10

#define Z_PROBE_X2 265

#define Z_PROBE_Y2 10

#define Z_PROBE_X3 45

#define Z_PROBE_Y3 190

update i see this in the logs 
17:24:10.666 : Error:Activating z-probe would lead to forbidden xy position: -35.000000, 45.00

If you changed the settings in the config.h  you will need to update the eeprom with a
M502 ;read config
M500 ;save to eeprom


or just change the eeprom values using repetier host eeprom editor
