Modify TinkerGnome source code to swap round hotend heater 0 and 1

Posted · Modify TinkerGnome source code to swap round hotend heater 0 and 1

Hey all,

 

My hotend heater blew the other day and since then no matter what I change multiple times temperature sensors or heaters (30w,35w and 40W) with base pid settings for each watt the autotune always fails by over shooting over 20c.  I have tried all suggestions on the forums for pid, but there is a consistent overshoot speed.

 

I think my mosfet might be damaged, so I want to build a firmware using heater and temperature device 2 as default. If it is the mosfet at least I can use the 2nd connection as a redundancy so I don't have to buy a new control board. 

 

Can anyone advice the source code reverences need to be changed? and would this just be in the Configuration or Configuration_adv as well?

 

Luke

    I think, swapping the pin numbers in "pins.h" is all what is needed.

     

    In "pins.h" go to the section "MOTHERBOARD == 72" and swap the pin numbers between

    HEATER_0_PIN  /  HEATER_1_PIN

    TEMP_0_PIN / TEMP_1_PIN

    good luck!

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
