BLTouch Probe Won't Deploy

@fcwilt
This is correct, but I cant seem to replicate the scenario in which it worked. -

This is correct, but I cant seem to replicate the scenario in which it worked.Well we are overlooking something simple.
Did you post what the DWC Z Probe readout value is?
Frederick
-
@fcwilt
Z Probe readout value is 0, and remains 0 for the entire homing attempt. -
Im unsure as to whether this means anything, but the BLTouch light remains a solid red when the machine is idle, as well as before and during the homing process. Of course the light shuts off when I power off the machine to prevent crashing, but the probe also deploys when power is turned off while the Z probe is occuring.

Well it's getting late and I've got to get some sleep.
Sorry we couldn't get it sorted in this session.
I will run some tests with my BLTouch and see I can determine what conditions could be causing your problems.
Talk to you later.
Good night.

No worries, same here. Thank you so much for the time that you have put into this issue. I greatly appreciate it!
Im hoping that this isnt an interference issue that will require shielding.
Thanks again! Good night.

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.

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.

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.
