Firmware for hotend of dual extruder head
-
@feynman137 In addition to what @Phaedrux has said, you also need to use the board prefix when setting the drive mapping using M569. For example, if the first extruder motor was connected to expansion board1 driver 0, then the M569 command would be M569 P1.0 Sn.
Yes, you need to define 2 tools so for example M563 P0 D0 Hn Fn and M563 P1 D1 Hn Fn.
Note also that when defining tools, the drive number (D) refers to the extruder drive as defined in M584, and not the physical drive. So your M584 might end E1.0:1.1 if the extruder motors were connected to drives 0 and 1 of expansion board 1. In that case, using M563, D0 will refer to physical drive 1.0 (expansion board 1, driver 0) and D1 will refer to physical drive 1.1 (expansion board 1 driver 1).

@deckingman thank you very much for this info. Especially the M584 comment, I had this all messed up. And in my head I was wondering how the code was tying heater to its respective extrusion drive. So this comment answers this question for me, it is in the tool definition. @Phaedrux thank you for the guidance you were correct I had not added the expansion board in the config tool. After doing this I was able to see the format that you displayed in your answer. I am posting my updated config.g file below.

@feynman137 I corrected my existing code but for some reason the tool0 and tool1 don't have the temperature reading.

; Tools
M563 P0 D1.1 H0 F0 ; define tool 0

Also, don't forget you can check for syntax errors with M98 P"config.g"
-
@phaedrux I did change the D values as suggested before I tried. But I have updated the code in the message thread to reflect this. Now the tool portion looks like:
; Tools M563 P0 D0 H0 F0 ; define tool 0 G10 P0 X23.9 Y-28.21 Z0 ; set tool 0 axis offsets G10 P0 R0 S0 ; set initial tool 0 active and standby temperatures to 0C M563 P1 D1 H1 F1 ; define tool 1 G10 P1 X-23.9 Y-28.21 Z0 ; set tool 1 axis offsets G10 P1 R0 S0 ; set initial tool 0 active and standby temperatures to 0CM98 P"config.g" gives:
It seems to be saying that S0 and S1 are not defined. But they are defined in my code here:
; Heaters M308 S0 P"1.temp0" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on expansion board pin 1.temp0 M950 H0 C"1.out0" T0 ; create nozzle heater output on 1.out0 and map it to sensor 0 M307 H0 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit M143 H0 S280 ; set temperature limit for heater 0 to 280C M308 S1 P"1.temp1" Y"thermistor" T100000 B4138 ; configure sensor 2 as thermistor on expansion board pin 1.temp1 M950 H1 C"1.out1" T1 ; create nozzle heater output on 1.out2 and map it to sensor 1 M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit M143 H1 S280 ; set temperature limit for heater 1 to 280C -
@feynman137 also wanted to add that if I switch the bed heaters to reading a thermistor from the expansion board instead of the mainboard I will no longer be able to get their temperature either. So the errors must be related to the expansion board. I can get the H0 to display a temperature if I list a mainboard thermistor so it likely isn't something related to the H0 config

Can you post the results of sending M122 and M122 B1 please?

So the mainboard does appear to be connecting to the expansion board.
-
The expansion board is running older firmware than the mainboard. You need to update it. If you've already uploaded the 3.3 zip file to the system tab in DWC, all you need to do is send M997 B1 to flash the expansion.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip
-
Actually I also see that you are using SBC mode. Have you done a sudo apt update sudo apt upgrade lately?
-
@phaedrux I did this last month I remember. But I don't think I flashed it to the expansion board. Because I ran the M997 B1 and reset the board. Now I can see all 6 temperatures!
-
Occasionally the expansion boards don't get updated automatically. I think that is being improved upon.
Regardless, it's also a good idea to check the installed firmware versions after an update with M115 and M115 B# for the expansion boards.
I would suggest that you do a sudo apt update and sudo apt upgrade again just in case. Ideally you'd only have to do that once for each major release going forward.
