BL Touch congif help needed

cinpro

what commands do I use to set the Z height from the bed. the instruction from the manufactures page has G-code but they come back as unknown commands, M851, M280 P0 S10 are examples. I know the distance between my nozzle and the lowest plastic part of the BL Touch is 8.2mm.

I also have the XY and Z all blinking question marks on the LCD display. the BLTouch self tests at start up. not really sure where to go from here.

BL Touch is connected at the Z-MIN and D11

using the newest developer Repetier firmware config

and a new development, Z home up instead of down, whether I invert the homing direction or not

Repetier

Z height is distance when triggered not untriggered distance. See z probe tutorial on our homepage how to define it with new dev firmware or set value simple in eeprom using host or server eeprom editor. Commands you showed are for different firmware.

Check forum for bl touch for more information on how to set it up, it has some specials you need to be aware of as discussed in some threads.

#define Z_PROBE_HEIGHT 0.1 this is distance nozzle to bed when probe triggers
#define Z_PROBE_BED_DISTANCE 10 how far to raise Z between probing points

#define Z_PROBE_SWITCHING_DISTANCE 1 this sets how far to move Z up to untrigger probe

these can be edited in the eeprom via repetier host
