M558 K0
Can you try without the K0? If you only have a single probe, best to leave it off.
Can you please share your full config.g?
What exactly do you have in your deployprobe.g and retractprobe.g files in the sys folder?
Does M401 and M402 work to deploy or retract the probe?
Does the probe deploy when you send G30?
Does the BLTouch pin deploy and retract when power is first applied?
How exactly is the BLtouch wired?
And The results of M122 and M98 P"config.g"?
Also send M558, G31, by themselves are see what they return. -

deployprobe.g and retractprobe.g files
I want to add that the filenames are deployprobe0.g and retractprobe0.g (so with 0 added), but I thought it is ok because of the K0.
The code is in GCodes3.cpp DeployZProbe() and RetractZProbe(), and looks ok.
The filenames must be all lowercase.
-
@charlie maybe your BLtouch is too near to the bed, please check
(from https://forum.duet3d.com/topic/17329/bl-touch/4)and then a higher height like H5 in the M558.

Unfortunately this doesnt change the outcome. I appreciate the attempt though.

Im not sure what this means. Please let me know if you would like to provide more information.

maybe your BLtouch is too near to the bed, please check
The print head is currently sitting around 200mm from the build plate (to prevent crashing).
BLTouch Body currently sits around 7.6mm from the bed (with the nozzle touching the bed). The pin in its retracted position sits around 2.1mm from the bed (with the nozzle touching the bed).

Does M401 and M402 work to deploy or retract the probe?
Yes, it does.
In this case, I think the issue is the K0. If you're going to use K0 in your config you're going to have to use it consistently. Your homing file doesn't specify the probe number when you use G30.
@charlie said in BLTouch Probe Won't Deploy:
M558 F600 H2 A1 ; Set Z probe. Feed rate: 600 mm/min. Dive height: 2 mm. Times to probe: 1.
G30 ; Z probe quickly (1 of 2 passes).
M558 F120 H5 A1 ; Set Z probe. Feed rate: 120 mm/min. Dive height: 5 mm. Times to probe: 1.
G30 ; Home Z by probing the bed slowly (2 of 2 passes).The G30 and M558 here must have K0 specified if you're going to use that.
https://duet3d.dozuki.com/Wiki/G30
Either remove all instances of K0 from your config and leave the deployprobe.g and retractprobe.g named as such, or convert entirely to using the number probe format. Meaning use retractprobe0.g etc and when using any M558/G30/G31 command elsewhere you must also specify K0.
I think since you only have a single probe it would be best to jsut remove all instances of K0.

In this case, I think the issue is the K0. If you're going to use K0 in your config you're going to have to use it consistently. Your homing file doesn't specify the probe number when you use G30.
Okay, that makes total sense. I removed all instances of K0 (in config.g, M558 and G31), but the issue persists.

If you have one probe you can leave the K parameter off everywhere. It defaults to 0 in anycase.
My BLTouch connected to a Duet 2 Wifi works fine and I have no K parameters anywhere.
I'm still baffled by your problem. I also still believe we are overlooking something simple.

Are you sure you've removed all cases of K0?
Can you try this?
Power cycle your printer
Before doing anything else, send M401 and M402 to test that the pin deploys and retracts.
If that works, send G30 by itself. Does the pin deploy? Does it give an error? Does the Z axis move? -

Here is the new Z Probe section of the config.g
; Z Probe M558 P9 F120 H8 R0 T6000 A1 B0 C"0.io4.in" ; Set Z probe type. ; K (Z probe number): 0 (1). ; P (Z Probe type): 9 (BLTouch probe). ; F (Feed rate. Probing speed [mm/min]): 120. ; H (Dive height [mm]): 3. ; R (Recovery time [seconds]): 0. ; T (Travel speed [mm/min]): 6,000. ; A (Max number of times to probe each point): 1. ; B (Heaters): 0 (Leave all heaters on while probing). ; C (Endstop input): 0.

Pin does deploy and retract with M401 and M402 respectively.
When calling G30. I get this error.

So, after getting this error:
g30 Error: G30: Insufficient axes homed for bed probingI threw
G92 X0, and thenG92 Y0in the console.The probe did deploy in this instance.
