My friend i appreciate the time you have spent trying to help. However it appears nothing was wrong. i had a close look at the bltouch and discovered there was a string of PETG wrapped around the bltouch pin, once i removed that all works as it should. Cant believe i didn't notice that earlier.

Can two panel dues be connected to the duet wifi and display at the same time?

also this, not sure if helps you

@Phaedrux yes, im using the ones that reprap config created.

Hi i just upgraded my Duet Ethernet to the newest reprap firmware 3.x
Before i was using reprap 2.x and my BLTouch worked good. I have not changed any connections. I've included my config.g and how i have the BLTouch wired, hoping someone can figure out what i did wrong. I used the reprap config tool. When I 1st turn on the printer the bltouch glows red, the probe deploys and retracts and then it sits there flashing red , it doesn't respond when i try to deploy or retract from the console and resetting the bltouch from the console doesn't help.

@jay_s_uk thank you, i will look again, i must have missed them.

Is it possible to use the smart effector with regular bearing type rods instead of the magnetic rods. My bearing type rods are tight and have no slop. Obviously I would have to figure a way to mount them to the smart effector which was designed to work with the magnetic ball ends.
Any thoughts, has anyone done this or will the smart effector only be effective with the magnetic ball ends?

When i press upload & start (top right of web Interface) , it uploads the file, then sits and sits and does nothing, i have to cycle power to get control back, if i upload file from the G-Codes Files section, everything works as always. Is this Upload & Start feature broken or do i need do do something? (i have tried on several different files, and file sizes.![alt text]

@phaedrux Please explain pressure advance, is this a setting in S3D or in the config file?
