Duet Wifi Thermocoupler Daughter board issue.

  • So I setup my board with the Duet Thermocoupler daughter board, but i am not getting any readings for "current" except a 2000c and I/O error fault. I read just about every wiki on this site and tried numerous things but nothing changes. i'm using E3D TYPE K THERMOCOUPLE (CARTRIDGE) and have set it in the 0 slot (using 100) on the daughterboard, but nothing i'm still getting the i/o error and 2000c. I did try connecting the Thermocoupler to E0 thermoistore1 on the board and change the G Code to see if maybe the Thermocoupler wire was bad. I did start getting a reading , but it was high like 350c and stable. but it was reading something. so, what does tell me? I'm thinking of either two things; my G code is wrong or the daughter board is bad. As i have tried just about every variation of G code I could think of. I'm at a lost. and i don't know how to troubleshoot the daughter board. I did try taking a wire and jumping over the connection on the daughterboard (read somewhere in the forum or wiki) and still got the same readings. I am open to any suggestions at this point.

    NOTE: this is a new printer build, so it hasn't even printed anything yet.

    This is my config.g file as it is now:

    Which version of the thermocouple board is it? If it's the newer version with two Error LEDs on it, you need X150 in the M305 command instead of X100 - see the instructions on the wiki.

  • That was it. I must have read the wiki a hundred times and did not catch the version of the daughter board. set my G code to 150 and voila, it works. thanks.

    I just checked the wiki and although the instruction to use channels 150-153 was included in the Hardware paragraph, it wasn't mentioned in the Firmware Configuration paragraph. I'm sorry if this misled you. I have now corrected it.
