Need help to config this probe

tecno

Hi guys,

I can run home all but then I need to calibrate so my config is not correct.

; Z-Probe
M558 P"!121.io1.in" P1 H3 F120 T6000 ;
M557 X15:400 Y15:400 S20 ; define mesh grid

Trying to run G30 error message pops up can not find z-probe 0

Can somebody sort this out for me?

@tecno said in Need help to config this probe:

M558 P"!121.io1.in" P1 H3 F120 T6000 ;

that line isn't valid. the P"!121.io1.in" should be C!121.io1.in"

@jay_s_uk

Changed that line = still works like the other and no G30

@tecno only probe types 8 and 9 are supported on toolboard. Use type 8 for IR probe. See https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Mini_differential_IR_sensor_by_dc42

Also, don’t think you need to invert probe with ! (exclamation mark). And connect to 3.3, not 5V. See https://duet3d.dozuki.com/Wiki/Duet_3_Tool_Board

OK done that but still G30 error

I can not find anything in gcode files to be edited. From where comes Z probe 0 ?
Anything missing in my config.g ?

Cheers Bengt

@tecno have you tried, M280 P0 S10 ; deploy BLTouch and M280 P0 S90 ; retract BLTouch
Have you got a deployprobe.g and a retractprobe.g ?

@peter247

This IR Probe fixed nothing moving here

@tecno you set the probe number with the K parameter in M558. If undefined it defaults to probe 0.

tecno

@engikeneer

Tried K0 K1 K2 still the same error

droftarts

@tecno please post your current config.g, response to M122, and check your toolboard firmware version matches your mainboard version. And show a picture of your wiring.

@droftarts config.g m122.txt

probe works running home all but I can not calibrate

droftarts

@tecno Please send M122 B121, post your homeall.g, and if possible post pictures of the IR probe wiring on the Toolboard.

In your config.g:

M584 X2 Y1 Z3:4 E0                           ; set drive mapping

You aren't using the toolboard extruder?

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.io1.in"

You don't need to enable pullup resistors (with ^ character) on X and Y, only Duet 2 using 'probe.in' need it.
On Z, this may be conflicting with the probe, change this to M574 Z0 S2. This may cause your Z homing not to work, depending on how homeall.g and homez.g are configured. I expect these are not using G30 to home at the moment.

; Z-Probe
M558 C"121.io1.in" P8 H3 K2 F120 T6000          ; 
G31 P50

Use K0 or leave the K parameter out entirely. If you really want to set the probe number, and set it to K2, then use G30 K2 when probing.

M308 S0 P"temp0" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin temp0
...
M308 S1 P"121.temp0" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin temp1

You're using the RRF configuration tool's default thermistor. Find out what thermistors you actually have and update these lines for more accurate temperature readings.

Good morning Ian,
I am not using the toolboard extruder, bowden to get as light printhead as possible on my Chiron.

Made the changes to M574, not working on Z lifts up Z and error Homing failed

M558 no K

M308 both work but how accurate Bed is Anycubic original and Hotend I do belive this is E3DV6 sold by them.
