BLtouch with Reprap Firmware 3.0

Adamfilip · 9 Jan 2020, 03:29

Cant seem to get my BLtouch to work after updating to Reprap firmware 3.0

hoping for some advice

This is my current config

Funny, I just ( about 20 min ago) got this working for myself.

I'm sure there are still things wrong with my config.g but you can look at it here. I would also have you look at the Duet/BLTouch guide posted here. You didn't mention which Duet board your using but lets just say its the Duet 2 Wifi. Look at the wifi section of that page. Pay special note to where to connect the BLTouch to the board. Heater3 in the case of the Duet 2 Wifi. If you connect your BLTouch to those pins, and use the probe section from my config, you should be good:

 M950 H3 C"nil"                                 ; Disable heaters h3-h7 to free up pins
M950 H4 C"nil"
M950 H5 C"nil"
M950 H6 C"nil"
M950 H7 C"nil"
 
; Z-Probe
M950 S0 C"exp.heater3"                         ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H10 F800 T2000            ; set Z probe type to bltouch and the dive height + speeds

The M950's with the C"nil" are there to free up those pins. You only really need to free up H3 for the BLTouch in this case, but I figured I wasn't using those so I'd free them all up.

Let me know if you have any questions

jrsphoto · 9 Jan 2020, 05:16

That looks good.. These V3 /config.g files are complicated. More so than with versio 2.x I think. Have you tried it

jrsphoto · 9 Jan 2020, 05:18

@Adamfilip said in BLtouch with Reprap Firmware 3.0:

M950 H7 C"nil" ; Disable heaters h7 to free up pins

One change.. Change:
M950 H7 C"nil" ; Disable heaters h7 to free up pins

to

M950 H3 C"nil" ; Disable heaters h3 to free up pins

Adamfilip · 9 Jan 2020, 05:31

I managed to get it to deploy in tests but when I run homeall
it gets to the point where it centers the head

then it gives me the error
Currently im getting this error

Hallo, can you over a Macro or a G-Code push the BLTouche Pin in or out.
I have the BLTouch config like you and the BlTouch don´t move the Pin.

I have the BLTouch wired on Heater3 (PIN8) on the Duet Wifi Board.
i take the G-Code to test M401 / M402
or
M280 P3 S10 I1
M280 P3 S160 I1
M280 P3 S120 I1
nothing move it.

With the old Firmeware 2.05 the Pin Move in and out.

Have you also adapted deployprobe.g and retractprobe.g?

@CupaCabra said in BLtouch with Reprap Firmware 3.0:

M280 P3 S10 I1
M280 P3 S160 I1
M280 P3 S120 I1

Now you have to use
M280 P0 S10
M280 P0 S160
M280 P0 S120

CupaCabra · 9 Jan 2020, 11:25

Hello,
yes i have but i don´t now is it right.

deployprobe.g
M280 P3 S10 I1

and in retractprobe.g
M280 P3 S90 I1

i hope there are right

DIY-O-Sphere · 9 Jan 2020, 11:26

change P3 to P0 and remove I1

CupaCabra · 9 Jan 2020, 11:27

@DIY-O-Sphere
i change the Code in the Config now an test it.

CupaCabra · 9 Jan 2020, 11:32

It´works with
M280 P3 S10 ......

thx so lot

droftarts · 9 Jan 2020, 11:50

@CupaCabra Great! Please post the 'Z-Probe' section of your config.g to show how you resolved this!

Also, you don't need to unassign the heater channels in RRF3 with M950 H3 C"nil", as they are not assigned by default. Only a few pins are assigned by default, and only need to be unassigned if you use them for something else; see https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Duet_2_WiFi_Ethernet_and_Duet_2_Maestro

M280 P3 S10 ......

Now I am confused.
You will find exact your configuration in
https://duet3d.dozuki.com/Wiki/Gcode#Section_M280_Set_servo_position

And we have done it succesfully on a buddys wifi exact that way with heater7.
Are you shure you have update to the stable and not to a older beta.
I think there you had to trigger the heater instead of the servo channel.

Also, you don't need to unassign the heater channels in RRF3 with M950 H3 C"nil"

The beta would explain that too.

CupaCabra · 9 Jan 2020, 12:26

so i have change the

deployprobe.g
M280 P3 S10

retractprobe.g
M280 P3 S90

if i test with a Marco file
The pin go´s out with S10 und retract with S90

I think it´s right.
