Duet wifi + duex5 + bltouch
-
undefinedundefined
I followed a lot of guides but with no success. I run firmware 3.3 on both paneldue and duet wifi, i tried the bl touch with another duetwifi without the duex5 and i got it working, so the bltouch is not damaged. I checked wiring multiple times with a voltmeter and they're ok. I connected: 2pin cables to zprobe pin next to paneldue -white to IN -black to gnd 3pin cables to pwm5 on duex5 -red to 5v aux -orange to e6 pwm -brown to gnd in Macros i created a Bltouch directory with retractprobe.g (m280 p7 s90) deployprobe.g (m280 p7 s10) The bl touch doesn't self test or even light up after turning on the board, when i imput m401 or m402 it starts blinking red but nothing happens, i also get the error heater 7 not found on paneldue. Here it is the config.g fileundefined

@marcocha If the BL touch is not self testing, it's not getting power. It just needs 5V on red wire, brown to GND to do the self test. Check you have:
If you have a Duex v0.9 or v0.9a board, check that you have a jumper on the "5V AUX JUMPER SELECT PINS" between the 5V AUX and 5V INT pins.
Should say "Duex v0.9 or v0.9a board or later", but you get the idea! https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Duet_2_WiFi_Ethernet_with_Duex_2_Duex_5_or_Expansion_Breakout_Board
For BL touch definition you have:
; Z-Probe M950 S0 C"exp.heater7" ; create servo pin 0 for BLTouch M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds M558 P9 C"^zprobe.in" H5 F120 T6000For the macros you have:
in Macros i created a Bltouch directory with
retractprobe.g (m280 p7 s90)
deployprobe.g (m280 p7 s10)Also, your M280 is wrong. You created S0 as the servo number. The M280 needs to refer to this, not the heater number, so should be:
retractprobe.g M280 P0 S90 deployprobe.g M280 P0 S10See https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Software_setup_RepRapFirmware_Num_3

@droftarts thank you for your answer, the jumper solved the 5v issue and now when i turn up the board the bltouch does the self test correctly, but still nothing with m401 or m402.
I changed m280 as you said, i think the problem lies in the pwm definition because i get error:heater 7 not found on the console as soon as i turn it on. My issue doesn't seem to be listed in the troubleshooting, i already checked that. -

If you have a DueX attached, one of duex.pwm1 thru duex.pwm5
So use
M950 S0 C"duex.pwm5"Ian

@droftarts i'm totally blind, didn't see that. Even if it still says error heater 7 not found now m401 and m402 works! Thank you very much again

@marcocha I expect there’s another line calling heater 7 somewhere in config.g. Send M98 P”config.g” and it should report any errors.
