BlTouch Issues
-
Hi,
Until yesterday, BlTouch v3 worked correctly, I had it connected to a Duet 3 Mini, to socket io0...
But I have decided to install a screen + Due panel, looking at the documentation, it indicated that if it is connected with the 4-wire cable, you MUST connect it to Io0, if not it does not work.
So I have moved the BlTouch to Io4, changing config.g... but now it doesn't work, it does the selftest, but when you do a Home, it doesn't deplaoyMy previous configuration that DID work:
; BLTouch M950 S0 C"io0.out" ; Create a servo pin on io7 M558 P9 C"io0.in" H5 F240 T10800 A5 ; set Z probe type to unmodulated and the dive height + speeds G31 P25 X-28.00 Y-13.00 Z0.90 ; set Z probe trigger value, offset and trigger height, more Z means closer to the bed
; deployprobe.g ; Called to deploy a physical Z probe ; M280 P0 S10 ; Deploy the BLTouch pin
; Called to retract a physical Z probe ; M280 P0 S90 ; Retract the BLTouch pin
My current configuration that does NOT go:
; BLTouch M950 S0 C"io4.out" ; Create a servo pin on io7 M558 P9 C"io4.in" H5 F240 T10800 A5 ; set Z probe type to unmodulated and the dive height + speeds G31 P25 X-28.00 Y-13.00 Z0.90 ; set Z probe trigger value, offset and trigger height, more Z means closer to the bed
; deployprobe.g ; Called to deploy a physical Z probe ; M280 P0 S10 ; Deploy the BLTouch pin
; Called to retract a physical Z probe ; M280 P0 S90 ; Retract the BLTouch pin

@peirof did you upgrade to 3.4RC1? if so, this is a known issue.
use the build from here https://forum.duet3d.com/topic/27139/rrf-3-4-0beta7-5-sbc-servo-only-responding-once-after-reset/10?_=1644995776018 -
@jay_s_uk in this moments, not sure, but i think remenber i have 3.4.0 Beta XX??? i check after

In the post you have linked... direct to Drobox folder...
Firmware Duet v3 Mini 3.4 BlTouch
this is supposed to be the firmware, with which I have to update my Duet 3 Mini... but I have two doubts:
A- It is not in the usual format. Correct?
B- It is updated in the same way. With the DWC? -
@peirof use the .uf2 and yes through DWC
-
@jay_s_uk
Tomorrow more..., but dont works after apply firmware...
Panel Due... only works in Io0? -
@peirof See https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_connecting#wiring-the-bltouch
For Duet 3 Mini 5+, use IO_1, IO_2 or IO_3.
Don't use IO_4 (okay for MB6HC, but not for Mini 5+), use one of the above. It's because of pin capability, only IO_1, IO_2 and IO_3 are PWM capable. See https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mini_5+_Hardware_Overview#io-port-pin-capabilities

@droftarts mmm...
The tests that I was going to do tomorrow, were in that sense, try other shockets ...
Thanks for the conformation...
Bltouch, does it work with the latest Firmware release?
