I hope my self adjusted settings are ok.

@uneumann36 A couple of comments:

 M558 P9 C"^io7.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

You don't need to enable the pullup resistor on the Duet 3. Remove ^ from the above line.

M308 S0 P"temp0" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin temp0
...
M308 S1 P"temp1" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin temp1

You are using the default thermistor settings. What hotend are you using for the 3-into-1? Check what thermistor it comes with, and change the M308 line accordingly for better temperature accuracy.

For the bed thermistor, I think the Ender 5 uses the Marlin default thermistor 1 setting (100k Epcos). Change the B value in the M308 line for the heated bed to B4092.

I can't comment on your tool change macros; 3-into-1 hot ends often require a lot of tuning to get the filament change smooth.

@droftarts
Thank you very much for your advise.

What do you mean with :
You are using the default thermistor settings. What hotend are you using for the 3-into-1? Check what thermistor it comes with, and change the M308 line accordingly for better temperature accuracy. ?
It is the same like origin in Ender5
Or do i understand something wrong?

@uneumann36 The default setting for thermistors in the RepRapFirmware configuration tool is B4138. I don't think anyone uses this thermistor any more.

I think some Ender 5 come with E3D hot end. If yours is standard, then like the bed, change the B value in the M308 line for the hot end to B4092.

Perfect, i will try this in the evening.
Thank you

@droftarts
Hi

So i try your advise.
About the thermistors , all settings are good.

But when i delete the Line :
M558 P9 C"^io7.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

Then the BLT is not working and DWC show the failure :
G28 Z
Error: in file macro line 8: G30: Z probe 0 not found
Error: Homing failed

droftarts

@uneumann36 I didn’t say to delete the line, just delete the ^ character! So line should be:

M558 P9 C"io7.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

@droftarts
Oh sorry,
Then I got it wrong

Thank you
Works well
