How do I set the offset between nozzles/ head origin
-
If the distance between nozzles is 18mm, set one of the offsets to 9mm and the other to -9mm.
What exactly is the error message you get when you try to activate tool 0?
-
the error message says temperature excursion exceeded 15*C

Thanks for reporting that, I've fixed the link.

I was able to go through the auto tuning for both nozzles successfully. Now that I have my new M307 numbers do I have to remove the M301commands from the config file? I'm just not sure where the new numbers should be placed / the sequence of commands.
-
Yes you should remove the M301 commands.
The restrictions on the order in which commands are placed in config.g are listed at https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Cartesian_printer#Main_configuration_file.

after auto tuning should I just send M500 to save the new settings? or should I be manually writing it into the config file? these are my updated settings after auto tuning but i'm still getting heater faults.

;*** If you have a Duet board with 1K thermistor series resistors, change R4700 to R1000 to the following M305 commands
M305 P0 T100000 B3950 R4700 H0 L0 ; Put your own H and/or L values here to set the bed thermistor ADC correction
M305 P1 T100000 B4719 R4700 H0 L0 ; Put your own H and/or L values here to set the first nozzle thermistor ADC correction
M305 P2 T100000 B4719 R4700 H0 L0 ; Put your own H and/or L values here to set the second nozzle thermistor ADC correction
;M301 H1 P10 I0.10 D100 T0.50 S1.0 ; PID settings for extruder 0
;M301 H2 P10 I0.10 D100 T0.50 S1.0 ; PID settings for extruder 1

You can do whichever you like. But remember these:
1. Settings saved with M500 are saved in config-override.g and will only be used if you have a M501 command near the end of config.g. The M501 command simply runs config-override.g.
2. If you have a M501 command near the end of config.g then any M307 or M301 commands in config-override.g will override settings in config.g.

After doing everything suggested I'm still getting heater faults, is there anything else I can do? Sorry for all the questions this is my first time playing around with dual extrusion.
-
Which type of heater fault are you getting? Have you run M307 H1 and M307 H2 to check that the values set in config.g are the ones being used?

I did run both of these and the values are definitely set. I'm still getting the same fault message as before.

It seems to be ok now that I've set standby and running temps to 0 under G10. I'll do some more testing today and see what I come up with it seems to be those G10 temps that are throwing everything off
