problem with homing z z probe already trigered at start of probing move

BLTouch troubleshooting: https://duet3d.dozuki.com/Wiki/BLTouch_Troubleshooting

Normal operation is:

When the Duet is first powered up, the BLTouch should perform its self test, which is to light up with red light, and extend and retract pin twice. If this doesn't happen, +5V and GND are not connected correctly.
Send M280 P0 S10 to extend pin. If this doesn't work, check the wiring to the servo pin. Send M280 P0 S90 to retract the pin.
The sys/deployprobe.g file and the sys/retractprobe.g file should contain the above two commands, one command in each file. Send M401 to extend the pin. If this doesn't work, check your sys/deployprobe.g file contains M280 P0 S10. Send M402 to retract the probe, and if this doesn't work, check sys/retractprobe.g contains M280 P0 S90.
With the probe retracted, check in DWC the Z-probe value in the Status panel. It should be 0. If it is 1000, check the probe trigger wire (usually white) is connected to the correct input pin.
Send M401 to extend the pin. VERY lightly, touch the end. The Z-probe reading should go from 0 to 1000. If it goes from 1000 to 0, you need to invert the probe. If it doesn't change, check the wiring again.
If doing the above triggers the alarm (flashing red), send M280 P0 S160 to release alarm and retract probe.

As you're using a clone BLTouch, and there was another thread recently about clones not working properly (see https://forum.duet3d.com/topic/23218/strange-bltouch-behavior-after-update-to-3-3-0-b3), I expect it could be that the output is inverted, and it reads 1000 when not triggered, and 0 when triggered. If so, invert the probe by changing your M558 line to:

i have just ordered proper bltouch will connect it tommrow and go from their also instaling the end stops if you coudld help in the code for this ill add it in would you like the code i have right now many thanks

droftarts

@mobietec I have mine set like this:

; Endstops
M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop" ; configure active-high endstop for low end on Y via pin ystop
M574 Z0             ; configure Z-probe endstop for low end on Z

I am using the X and Y endstops, BLTouch on Z. The only physical change is that I have wired them using the outer two pins (of three) on each microswitch, for NC (normally closed, or active high) operation, which is more reliable. I think you won't need to change your homing files much, except comment out any lines related to sensorless homing. See https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Microswitch

If you want to post your current config.g for reference (or maybe after you have made the changed to endstops), please do. It would be good if you could use the 'code' tags around long bits of code, like the endstop code in the black box in this post, to make it easier to read. Click the '</>' icon at the top of the post edit window to insert these tags, and paste the code in between.

ok for the next bit nd thank you so much for all your help im slowley learning this i think i need to set the off set propley of the bl touch i have gourn back to clone it seems to be working

when i home the z it works so to speek i need to set the bltouch i di put a -37.6 and a 37.6 with no luck the proble is off the bed the nozzle is correct front left ie nearest to you on left

1 i think i need to set home 0 to center trying to look ant fined out how and tryng to do off set

somtimes i think i bit off more that i can chue with duet3 board its very compleacted for me but the end rerult should be good many thakns

Phaedrux

The G30 will just start probing at whatever XY position it's currently at, so you'll need to manually position the probe in the homeall.g and homez.g files so that the probe is where you want it to be before the G30.

@phaedrux
@phaedrux my updated config file
i cant get the bltouch to deply now grrr i am trying to look for answers befor i post first i have the bl on io3 now their are two grounds form touch that are wired together sence on io out and triger on ioin

i have checked for contunety lol i cant spell today and i have also tried 3.3 and 5v lines and i have tried diffrent probs still get same

Does M401 and M402 work?
Does M280 P0 S10 or M280 P0 S90 work?
What do you have in your deploy and retract macros?
Are those deploy and retract macros located in your /sys/ folder?

Mobietec

@phaedrux no im trying a clean install see if that helps

yes

Phaedrux

99.9% of the time it's wiring.

Mobietec

@phaedrux i fully understand that i have checked and rechecked im using duet 3

bl conected to io3

5volt to 5volt in bl
io out to sig
both grounds from bl to gnd
and out(z) to io3 in

rom socket to bl no broken conections and correct readings ie cable conected ok

hope this helps

Are you using io3 or io4?

@phaedrux io3

If you are connected to io3.... and your config is using io4....

Mobietec

@phaedrux i changed it just in case that was a problem port made no diffreance im pulling my hair out i have tested both bl in a marlin boards and work as they should just will not work in here

i have also reflashed board to 3.2 no luck i was on 3.3 so im going to put that back on

Phaedrux

Ok, so your config is using io3 now as well?

when you tested on the marlin boards did you use the same cable harness?

Can you show a photo of your BLtouch connection at the duet board io3 connection?

Mobietec

@phaedrux yes same harness i have to change pins over so 5v n sig were correct
