Toolboard + NO NPN probe

@tecno you can't map a pin twice. get rid of the M574 Z0 line

Morning, so it is OK with IR but not switch. Still learning

tecno

@jay_s_uk

Did get rid of the line.

So what is wrong?

; Endstops
M574 X1 S1 P"!121.io2.in" ; configure active-high endstop for low end on X via pin ^io3.in
M574 Y1 S1 P"!io0.in" ; configure active-high endstop for low end on Y via pin ^io0.in
; M574 Z1 S1 P"^!121.io0.in" ;

; Z-Probe
M558 C"^!121.io0.in" P5 H10 F120 T8000 ; F120
G31 P50 X0 Y20 Z0 ;3.490
M557 X5:340 Y25:400 P4:4 ; define mesh grid

Greatful to get some help here.

@tecno might be a good idea to post your whole config and an output of M98 P"config.g"

@tecno well there you go. use P8 and not P5

Hard DIVE into the bed, led on probe lights up but no reaction to that

@tecno maybe you don't need the pullup?
best to check these things far away from the bed rather than relying on that as a last resort

With probe not triggered Prove value is 0 triggered is 0

If I set probe not inverted Probe value is 1000 triggered still 1000

No change whatever I try

@tecno maybe you need a diode as detailed here https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_connecting#npn-output-normally-open-inductive-or-capacitive-sensor?
other than that, no idea

@tecno said in Toolboard + NO NPN probe:

With probe not triggered Prove value is 0 triggered is 0
If I set probe not inverted Probe value is 1000 triggered still 1000

Either you have no signal on the pin, or it is constantly tied to 3.3V by the probe. Check function of the probe stand-alone with a multimeter: What voltages do you read when the probe is triggered/untriggered?

A third possibility might be the port being defective, but first, check your probe signal.
