mixing extruder diamond hot end

Iamarobot

Hi,

I am trying to set up a mixing extruder with diamond hotend but after rep host connects i get:

17:43:58.564 : No start signal detected - forcing start 17:43:58.580 : N1 M11034 17:43:58.580 : N2 M11536 17:43:58.580 : N3 M10536 17:43:58.580 : N4 M11435 17:43:58.595 : N5 M111 S698 17:43:58.595 : N6 T060 17:43:58.595 : N7 M2022 17:43:58.595 : N8 M8019 17:43:58.595 : N9 M105*46

It doesn't seem to be working correctly . there is no m115 command response I can see so there is no eeprom setting available.

There might be some issue with pins use for one of the extruders or something? Has anyone done this setup before?

How can I attach my configuration.h file?

I am using ramps v1.4 with MEGA2560 .

I have added an extra driver for the 3rd extruder manually.

thanks.

Your firmware is not communicating. So it is crashed or using different baud rate.

What did you do with the 3rd extruder - set pins manually for ext2? There are no predefined pins for this so you need to add them in pins.h for the ramps board.

Maybe first set NUM_EXTRUDER to 2 and see if it starts/connects and only then add 3rd extruder.

Afterwards have a look into eeprom for missing weights for the virtual extruders.
