BL Touch congif help needed
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.
Ramps 1.4 mega
BL Touch is connected at the Z-MIN and D11
using the newest developer Repetier firmware config
