@Veti said in Duet Maestro and BLTouch, M401 and M402 do nothing:
however the trigger signal is zprobe.in
its written like that on the site you linked
Oh I see. I changed both of the .mods to .ins on the first go. Now when I only changed the M558 to zprobe.in, M401 started working. Thanks a lot! This can be marked as solved 
@Veti said in Duet Maestro and BLTouch, M401 and M402 do nothing:
that should be zprobe.in
I tried this, didn't help. However, it changed the DWC value of Z-probe from 1000 to 0. Anyway, the instructions (https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_BLTouch) clearly state: "On a Duet Maestro it is zprobe.mod".
Hi,
I'm running Duet Maestro with RepRap 3.1.1. I have a genuine Antclabs BLTouch 3.0+, could be 3.1 as well.
The BLTouch is connected as instructed 
On power-up the BLTouch deploys twice and it's lighted up implying that it is in a working state. However, I get nothing with M401 and M402. I have done everything according to these instructions: https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_BLTouch (using those instructions that apply when you have a Duet Maestro with RRF 3)
I have also checked the BLTouch troubleshooting section (https://duet3d.dozuki.com/Wiki/BLTouch_Troubleshooting) but nothing seems to help.
My DWC shows value '1000' in a red box at the Z-probe section.

Hello everyone,
I'm in the process of upgrading my Ender 3 Pro fans to 12V. I'm using Duet 2 Maestro with firmware 3.1.1 (2020-05-19b2).
I have a buck converter with inputs wired to VIN+ and VIN-. The converter is set up to output 12V and this is verified with multimeter.
I have wired the buck converter OUTPUT+ to both V_FAN_A (jumper middle pin) and V_FAN_B (jumper middle pin). (Same problem existed when I had it only wired to V_FAN_A)
When I power up the machine and start checking the fan ports with multimeter I get the following results:
Always-on-fan 12V (correctly).
FAN0, FAN1 and FAN2 0V (correctly).
After this I heat the hot end to 55 C (fan temperature threshold at 45 C), set the part cooling fan to 100% from DWC and check the ports with multimeter again:
Always-on-fan 12V (correctly)
FAN0 12V (correctly)
FAN1 7V
FAN2 7V
So something is wrong with FAN1 and FAN2 voltage and I can't figure out what it is. Can anyone help?
