i have the wires plunged in for a micro switch on the board side ill unplug them but i have no micro switch plugged into the wires

but i did originally have a micro switch on my machine on the z axies and would this be the problem

M574 X1 Y1 Z1 S0 ; Define active high microswitches

do i need to change m574 g code to this
M574 X1 Y1 Z0 S0 ; Define active high microswitches

thanks

what about the hole bed looking high in calibration result

hi i got my ir prob working but i have a wonky bed looks flat but its not how do i in-cress the bed mesh probing points
here's my macro for bed mesh

M557 X20:250 Y20:250 S40 ; Define a 6x4 point grid for measuring the bed
G28 Y ; Always home Y
G28 X ; Always home X
G28 Z ; Always home Z
G29 S0 ; Run probing sequence defined by M557 above S0 parameter saves the height map in a file on the SD card,
M374 ; Save calibration data. Default is sys/heightmap.csv
G1 X0 Y0 F3000 ; move to position to home

also my hole bed seems to be high i am sure i have missed are misunderstood some thing how do i get most of it back into the green

yes i find the documentation is not well written are organized i.e start reading this page go to that page come back to this page before you know it you have 20 tabs open and you lost some bit that you need …..... if your doing bed mesh next i found a great right up here
