BLTOUCH ERRO ON 3.4.0beta5

josegerdes

I have Duet 3 Wifi Mini ( plus i think ) and BLTOUCH COMMANDS ARE NOT WORKING... All updated...

https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.0beta5
i had to update because my sensorless was with a bug.

@josegerdes please do the following:

explain what is not working with your BL touch
Post your config.g, retractprobe.g, deployprobe.g using the </> command in the text formatting for each one when you post them on here so we can view them easily.

No need to should with the all capital letters!

@t3p3tony Sory about Captal letters! Long time i dont use forums. I like this community a lot.

So my bltouch its a bit strange...
these commands i got it working.. i was using like

M280 P3 S10 I1 ; deploy - it was wrong

M280 P0 S10 ; deploy
M280 P0 S90 ; retract
M280 P0 S120 ; test mode
M280 P0 S160 ; clear test mode or error condition

but i am having other error, sometimes my bltouch get stuck up and then do a erro and i cant reset, its like the magnet its so strong

@T3P3Tony SelfTest work but probe not work, make the bltouch get stuck some times.. @dc42

@josegerdes said in BLTOUCH ERRO ON 3.4.0beta5:

M558 P9 C"^io3.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

Remove ^ from pin name. Pull up resistor should not be set. See https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Software_setup_RepRapFirmware_Num_3

So:

M558 P9 C"io3.in" H5 F120 T6000

If the probe doesn’t deploy with M401 and retract with M402 (your deployprobe.g and retractprobe.g look correct), check your wiring, particularly the orange wire, which controls the pin deployment.
