BLTouch Probe Won't Deploy
-
@fcwilt
So I did this, but with one exception. I didnt jog the z to be 3mm off the bed, as I was concerned about crashing the nozzle.The probe did not deploy, and the error: "Error: Probe was not triggered during probing move" was displayed on the console.

@joergs5 said in BLTouch Probe Won't Deploy:
@charlie a last additional idea: M208 has Z minimum 0 and the BLTouch starts at 3 mm height. It may be that it cannot probe below 0 because of M208. This was changed in 3.4 somewhere if I remember correct, but if you use 3.3 firmware, it may be a try to set the M208 Z limit below 0.
Something odd happened that may help those smarter than I!
I issued an
M208 S1 Z-100command in the DWC console (which is along the lines of what I believed you asked me to do). I then issued aG30command. Please keep in mind that this was after I did what @fcwilt asked, which was to issue aG92 Z3command.The print head seemed to move down around 3mm, and then the probe deployed.

I made a post but came back to find your new post.
I need to think.

Here is the current Z Probe section of the config.g file, containing the M950, M558, and G31.; Z Probe M558 K0 P9 F120 H3 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.

A higher offset number moves the nozzle closer to the bed.). ; K (Z probe number): 0.

Thanks.
Let's changes things just a bit:
M950 S0 C"0.io4.out" M558 P9 C"0.io4.in" H3 T6000 F120 A1 R0.2 B0 G31 P25 X0 Y22.0 Z3.105Reset and try what I suggested before BUT lets use G92 Z7 instead of G92 Z3

Same problem. Probe did not deploy. Same error: "Error: Probe was not triggered during probing move" -

And yet when you issued the M208 S1 Z-100 and then the G30 it seemed to work?

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

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.
