Having problems with the bltouch, duet 2 wifi

A Former User

can anyone see what the problem is with my system.g folder, and tell what to do too get the bltouch too work propperly. it seems like everything works fine when i control the probe manually. but if i try too home it, it won't deploy

@remixbot said in Having problems with the bltouch, duet 2 wifi:

M558 P5 C"^e1temp" H5 F120 T6000

This looks weird (at least for me). I would use Z probe input, not thermistor input. Also I do not see M950 for servo pin controlling bltouch defined.

How do You control it manually? Do You have deploy.g and retract.g files?

There is an example also how to set this up:

M558 P9 C"^zprobe.in" H5 F120 T3000  ; BLTouch connected to Z probe IN pin
M950 S0 C"exp.heater3" ; create servo/gpio 0 on heater 3 pin on expansion connector
...
M280 P0 S10 ; send control signal to BLTouch through servo/gpio 0

A Former User

i used probe.in for the black and white wires here earlier, so i just had to try something else. but no im not currently using the deploy\retractprobe.g at the moment.

BoA

@remixbot So connect it back to z probe input, and servo pin to the right pin in expansion header.
Add to config:

M558 P9 C"^zprobe.in" H5 F120 T3000  ; BLTouch connected to Z probe IN pin
M950 S0 C"exp.heater3" ; create servo/gpio 0 on heater 3 pin on expansion connector

or exp.heaterx if other pin is used, create files:

deployprobe.g

M280 P0 S10

retractprobe.g

M280 P0 S90

@remixbot Did You create deplyprobe.g and retractprobe.g ?

A Former User

@BoA yes

BoA

Seems You have not defined endstop for Z axis.
Add

M574 Z1 S2

A Former User

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

A Former User

it won't deploy when issuing g29 either

BoA

@remixbot Will it home Z with G28 ? Deploy and retract probe for homing?

A Former User

@BoA i tried to issue g28 now, but it wouldn't deploy now either

BoA

@remixbot OK. Post result of M122 and M98 P"config.g". Also what do you have in homez.g/homeall.g file?

You might want to adjust position of homing point changing line with:

BTW - did You use configtool, and set bltouch there? it generates proper config files.

yes i did use config tool
