old bltouch is not working with RRF?

M401 ; deploy the probe G1 Z-155 F6000 ; quickly move Z down, stopping at the probe (possible because of M574 Z1 S2 in config.g) {1} {1} G1 Z5 F1200 ; immediately move the nozzle 5mm away from the build plate M401 ; make sure the probe is deployed still

You don't need this stuff and it won't work. To use the probe to home Z you only need the G30.

:Z-Probe M558 P9 C"^zprobe.in" H3 F120 T3000 ; G31 P500 X-32 Y13 Z2.9 ; Set Z probe trigger value, offset and trigger height M557 X15:225 Y15:225 S20 ; Define mesh grid ;M915 X Y S5 R2 DIT STOND OP ACTIEF

You're missing the M950 command to create the servo control.

As I posted above you need:

; Z-Probe
 
M950 S0 C"exp.heater3"                         ; create servo pin 0 for BLTouch
 
M558 P9 C"^zprobe.in" H5 F120 T6000            ; set Z probe type to bltouch and the dive height + speeds
 
G31 P500 X0 Y0 Z2.5                            ; set Z probe trigger value, offset and trigger height

M557 X15:215 Y15:195 S20                       ; define mesh grid

@Phaedrux @Lampie

M950 S0 C"exp.heater3"

That's correct if you have the yellow wire on HEATER3, but if you moved the yellow wire to HEATER5, it should be:

M950 S0 C"exp.heater5"

This line was in your config.g, not sure why you deleted it!

@Phaedrux that was error bad command in homey.g
but that was due to some left over commands that where there..
y is homing again. x is homing again Z is killing my heatbed so i have to switch it of fast. .

Phaedrux You don't need this stuff and it won't work. To use the probe to home Z you only need the G30.
so literary delete all lines in there except G30?

@droftarts i was in the morning on the photo on the other pin. after that i changed it to
pin 18 heater 5
the deleted line is due to the fact i had so much problems getting the probe to activate i used my old config files due to the fact i have problems understanding some explainations... i am sorry about that its on my end here.. sorry once again to trouble u guys.

i think its better to remove all and manualy level the bed again.. it just not working

As posted above, this is all that's needed to home Z with the probe.

G91              ; relative positioning
G1 H2 Z5 F6000   ; lift Z relative to current position
G90              ; absolute positioning
G1 X15 Y15 F6000 ; go to first probe point
G30              ; home Z by probing the bed

You can change the G1 X15 Y15 to move the probe into the center of the bed. But otherwise that chunk can go in your homeall after the X and Y are homed.

Until you get things working you should test that the probe is triggering properly using this static test method. Only once it's triggering successfully there should you move on to trying to home the printer just to save some crashes.

printer just to save some crashes.

i did try to do the static test but no joy
i have to shut it down because its crashing in the bed.

M280 P0 S10 and M280 P0 S90 do work on the probe

i tried the dynamic test also (just to be sure) but x homes en y home is working
but pressing Z is a bed crash..

i have to be the most challenging and annoying noob to u guys right now

If the M280 commands are working that means the servo is working. Test M401 and M402 to make sure it deploys and retracts to test your deploy and retract macros.

If the pin is dropping but not halting motion during a G30 that means there is a problem with the white wire going to the zprobe input, so double check that. Check for continuity . Check the crimps.

DennisD

M280 command do work.
m401 and 402 does nothing.
and thats it..

can this be due to the fact i have antlabs v3 probe?

DennisD

nevermind i removed al the wiring from the bltouch and i am going back to manual adjusting..
anyway thanks all

M401 calls sys/deployprobe.g and M402 calls sys/retractprobe.g. They are used in G30, too. So if they are not working, there's something wrong with these files. Are you sure you named them correctly, and put them in the sys folder?

You should be able to run them by sending M98 P"0:/sys/deployprobe.g" and M98 P"0:/sys/deployprobe.g". Using the full file path will check it is in the correct place.

can this be due to the fact i have antlabs v3 probe?

No, it should work fine.
