@PaulHew said in Maestro, RRF3 and BLTouch issues:
M950 S0 C"^zprobe.mod" ; create servo pin 0 for BLTouch
M558 P9 C"zprobe.in" H5 F120 T3000 ; BLTouch connected to Z probe IN pin, free up MOD pin
M950 S0 C"zprobe.mod" ; servo/gpio 0 is Z probe MOD pin
That should be the right code.
That's a bug, I have already reported.
Let it set to the e1heat. You have to adjust that later on in the config.g
The probe section then should look like that
; Z-Probe
M558 P9 C"zprobe.in" H5 F120 T3000 ; BLTouch connected to Z probe IN pin, free up MOD pin
M950 S0 C"zprobe.mod" ; servo/gpio 0 is Z probe MOD pin
Configuration for Ender3
config.json
@4lathe
It's still DuetMaestroFirmware.bin
@PaulHew said in Maestro, RRF3 and BLTouch issues:
That came out of the config tool that way round.
You have first to unassign zprobe.mod from the modulation pin.
Only then you can assign zprobe.mod to the PWM control.
Else the Bltouch is not selectable in the endstop tab.
That generates a proper configuration.
@felt342
After adjusting i never had an issue.
Maybe the jerk value for the extruder is too high.
While setting up PA today, I had the same issue. After decreasing jerk to 1000 mm/min I was able to print the test cube.
Hi Ky,
I had exactly the same issue, that was driving me crazy....
Check the Pin
"Try loosening or tightening the set screw slightly to adjust the trigger sensitivity."
There is a description how to set up the srew, but I can't find it currently.
In the end a quarter turn had reliably solved the problem.
Regards
Frank
Edit:
You can find the information in the manual
@felt342
It seams they have modified the newer ones.
The picture of the set screw isn't included in the manual anymore.
I have also found a video for the pin replacement on youtube .
So I think yes it is locked.

That's a common case with a geared extruder.....You will find that also documented in other threads
@kmhudgins
Have you replaced all files in sys folder? Or only the config.g?
Have you checked the version of your BLTouch?
You can check the probe by sending:
M280 P0 S120
For RRF3 the deployprobe.g and retractprobe.g have to be modified.
@dc42 said in Help with new config.g:
recent versions of BLTouch
Thank you for clarification. Now I am clear about why my BLT 2.0.... works without pullup (^)
Maybe a note in the wiki guide about the different versions of BLT would be helpful.
@dc42 said in Help with new config.g:
Not quite, you need the ^ in front of zprobe.in
That's a Maestro!

@PeteIHughes
If they are from RRF2 you have to edit the content
deployprobe.g
M280 P0 S10
retractprobe.g
M280 P0 S90
@PeteIHughes said in BLTouch will not deploy:
It does so twice on power up, but never again.
Then the Bltouch is working
Have you tried "M280 P0 S10" in DWC?
@PeteIHughes
Also check the endstop setting
That would use an connected endstop
M574 Z1 S1 P"zstop" ; configure active-high endstop for low end on Z via pin zstop
Normally with Bltouch the probe is used as endstop
M574 Z1 S2 ; Set endstops controlled by probe

M558 P9 C"zprobe.in+zprobe.mod" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
You have wired to heater 7 so the code should be
M950 S0 C"exp.heater7"
M558 P9 C"^zprobe.in" H5 F120 T6000
You don't need the mod pin....
@PeteIHughes said in BLTouch will not deploy:

https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe
The Z probe input pin will be zprobe.in on a Duet 2, or one of io4.in, io5.in or io7.in on a Duet 3. If using zprobe.in, you need to enable the pullup resistor using the ^ character in front of the pin name.
M558 P9 C"^zprobe.in" H5 F120 T3000
Should be
M558 P9 C"zprobe.in" H5 F120 T3000
The challenge in configuration tool maybe is to set up the probe.

That is the wrong resistor value for the Maestro

Standard fan setup:

M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency

As @Veti mentioned, try to generate a clean setup with the RRFCT
