Having problems with the bltouch, duet 2 wifi
-
Seems You have not defined endstop for Z axis.
AddM574 Z1 S2 -
the wierd thing is that i can use m401 and 402 and m280 p0 s10\90 without any problem. but it will not trigger when i issue g30 or g31 s-1
-
it won't deploy when issuing g29 either
-
@remixbot Will it home Z with G28 ? Deploy and retract probe for homing?
-
@BoA i tried to issue g28 now, but it wouldn't deploy now either
-
@remixbot OK. Post result of M122 and M98 P"config.g". Also what do you have in homez.g/homeall.g file?

@remixbot Ok, that seems to be wrong.

G1 X5 Y5 F6000 ;go to first probe pointBTW - did You use configtool, and set bltouch there? it generates proper config files.
-
yes i did use config tool
-
but can't seem to wrap mye head arround the pin assignment i config tool.
Pin Assignment
Input Pin
zprobe.in
Modulation Pin
zprobe.mod
PWM Control Channel (BLTouch only)
exp.heater3 -
@remixbot
Pin assgnemnt:
Z endstop
-
still crashing into the bed
-
Is BL Touch deployed, but bed not detected? Or not deployed at all?
Describe what and where You connected (from BLtouch). -
bed is not detected
-
the bltouch is connencted to gnd and signal on probe in. and pin 1, 2 and 8 on the expansion
-
@remixbot
post a picture of your wiring

@remixbot said in Having problems with the bltouch, duet 2 wifi:
G1 H1 Z-205 F360 ; move Z down stopping at the endstop
G90 ; absolute positioning
G92 Z0 ; set Z position to axis minimum (you may want to adjust this)To use the probe you need to use G30 as shown by BoA in his example homing files.
If your wiring is correct and the config uses those correct pins and it still doesn't trigger but the servo commands work, then it's likely a bad connection on the white wire, which is the trigger signal.
