bltouch wait time config
-
Hello. I have a doubt about bltouch config. On bltocuh docs, they state that a 100 milsec wait time has to be set in order to "wait" for bltouch to be ready (wait for what? I dont know). So the example config they give for inserting into the start gcode of the slicer is:
M280 P0 S160 ; BLTouch alarm release
G4 P100 ; delay for BLTouch
G28 ; home
G29 ; auto bed levelingThis 100 milsecs delay should also be inserted on Zhome file too like:
M280 P0 S160 ; BLTouch alarm release
G4 P100 ; delay for BLTouch
G30 ; home Z by probing the bed
M913 Z100
G1 Z6 F200
M564 H1Or it is not necesary since the bltouch configuration on config.g is:
M558 P9 C"io7.in" F100 H3.2 R0.2 T6000 A5 B1
Where the R value of 0.2 inserts a 200 milsec wait time for the proble to be ready each time probing is requested?
Deployprobe.g also has:
M280 P0 S160
G4 P100
M280 P0 S10Should that 100milsec be there or it is not necesary?

@Tinchus that delay is not required to use the BLTouch. However, the reason it is there is because you are also calling the alarm reset command before homing. This will reset any internal error on the BLTouch (i.e. when it flashes) but it takes a short time (100ms) to clear, hence the delay. Your homing will fail if you try probing wile the BLTouch is in an error state.
I don't use that in my config, but means that occasionally I have to manually reset any error on the BLTouch which admittedly can be a pain!

@engikeneer thanks for the answer. Can you share your config of bltouch?
