here is my Zidex printer configuration (two independent z axis) i am trying for the second BL touch sensor to deploy and retract process. the first tower works fine but for the second tower unable to use the bltouch sensor. do i need to create the file like heighmap, deployprobe and retract probe for the second tower? if it is what name i should mention for the files for the second sensor?
(i am using rrf3)

Note: i am not sure which pin should work for the zmin for the second tower bltouch sensor (i have tried by connecing e0stop for the zmin if it is right so the problem is from configuration.) please guide with this. if the second bltouch sensor spec is not applicable with this firmware what should i have to use?

i am trying to connect second BL Touch sensor either main bord or expansion board (Duet 2 Wifi + Duex 5 Expansion), which pin i need to use for zmin for the second sensor. i tried with endstop pins but its not working.

also let me know what to mention in config file, is that i need to create another file for deployprobe and retract probe?
firmware version i am using as RRF3

Hi,

i am trying to use two BLtouch sensor for my Zidex printer (two seperate Z axis), and i have connected two sensor control signal in to PWM4 and PWM5, also i connected one sensor Zmin wire into Z-probe in. please give a advise for second sensor Zmin wire connection in Duet2 Wifi board and i am using (firmware version 2.03). the following G codes are using in my configuration file. the second BL touch sensor Zmin i tried to connect with same pin but its not working.
Kindly let me advice with your idea.

Hi,

i am getting problem with connection between Duet2 Wifi to YAT, when i am sending a command to duet there is no response also i am unable to status of Duet. i did all the process before and i got the control for my 3d printer, after when it ask the password i couldn't able to connect because i don't know the password which i uploaded the G-Codes and configuration files from other person so i did reset and erased the previous data by pressing the buttons in duet board, now i am getting this problem. kindly let me know where is the problem coming from?
