In the deploy and retract files change the P3 to P0 and remove the I1

@Phaedrux i changed the macro test files to P0 and delted the I1 but didnt work, re added the I1 and the macros work, but when i try to home z i get this error message?
G28 Z
Error: in file macro line 9: G30: Z probe 0 not found
Error: Homing failed -
thanks everyone for your help, it is really appreciated !

Does that line in your config.g actually have double M558 at the start?
Can you post your full config.g?

That should be B57600 not 8

@Phaedrux Thanks for the help mate, did as you suggested and went to home all axis and got
G28 X
Operation has been cancelled -
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 failedi 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
M558line that configures your z probe -

i think you might need

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 ! -
@JTM said in Temprature sensor error unknown temperature sensor channel:
M558 M558 P9 H5 F100 T2000 ; set Z probe type to bltouch and the dive height + speeds
Can't believe I didn't catch that!
-
@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? -
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.
