Temprature sensor error unknown temperature sensor channel

@Phaedrux Thanks for the help mate, did as you suggested and went to home all axis and got

G28 X
Operation has been cancelled

Phaedrux

I suggest going through this guide to ensure endstops are working and motors are moving are going the right direction.

@Phaedrux Thanks for all your help Mate, still going through the checks, the motors and end stops seem to all be wired correctly and moving the right way, i keep getting this message when homing z

G28 Z
Error: in file macro line 9: G30: Z probe 0 not found
Error: Homing failed

i will keep looking the M280 deploy and retract macros work but homing doesnt activate the probe so im guessing the Gcode for homing is missing something?

please post your revised config so we can see your current M558 line that configures your z probe

i think you might need C"^zprobe.in" added to the line with M558?

M558 P9 C"^zprobe.in" H5 F100 T2000 ; set Z probe type to bltouch and the dive height + speeds

edit: presuming thats where your zprobe is connected?

Genius ! thanks mate did the trick now homes all axis ! temp sensor works, extruder works all i need now is to calibrate i think woohoo !! thanks so much to everyone for your help !

Can't believe I didn't catch that!

JTM

@Phaedrux you guys are awesome ! appreciate the help as i'm as green as it gets almost ! lol
Ive calibrated my steps so now all axis move the perfect distance, extruder extrudes exactly 100mm when i tell it too, only issue i have is homing Z. I have used the test and calibrate procedure in this link https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe
i have done the calibration several times i manually move the bed up to be catching a width of paper, send M92 Z0 comand to set sero. i then drop the bed down 10mm and send G30 S-1 and i consistently get an av figure of 1.8mm. Now i changed my congig.g code which was G31 X0 Y0 Z0 P25 to G31 X0 Y0 Z1.8 P25 and it still home 14mm high ? am i doing something wrong obviously?

Phaedrux

1.8mm trigger height sounds reasonable. 14mm high? Where is that coming from? How are you measuring that? After homing if you jog to z0 the nozzle should be touching the bed.

JTM

@Phaedrux i have a E3d super volcano on this machine so i measure from the bottom of the block with a ruler to the bed and it homes 14mm high every time. i can move the nozzle to the bed via the controls sure, but i thought it would home to the required printing height each time if set correctly?

JTM

@Phaedrux when i home Z it raises the bed hits the Zprobe then the bed drops 10mm or so?

droftarts

@JTM what height does DWC report Z is at after homing Z? If 0, but nozzle is off bed, post your homeall.g and homez.g

@droftarts its says 0 on the console

The print height gets set by the slicer.

The important thing is that after homing you can do a G90 G1 Z0 move and the nozzle touches the bed. If that works, then when you start the print it will go to the right height.

Maybe show a photo of what you mean with the 14mm if you still think something is wrong.

G90 G1 Z0

that did the trick ! so when the print starts it moves to z position 0? i didnt know that. I am trying a print lets see what happens but im finding i have to heat the extruder manually before starting a print. Ill figure it out tommorow

![0_1600329782267_E2B2A79B-9311-4AC2-BCFF-1A5728E3112A.jpeg](Uploading 100%) I have started a print almost completed ! There are a couple of bugs to iron out but this board is amazing! So quite ! I have the wrong nozzle for the print as it was a rush to see it working but almost done! Just printing in reverse ! Lol but I’m sure there is an easy fix for it !
Thanks heaps guys I really appreciate all the help !
