UM2+ simple firmware change


Recommended Posts

Posted · UM2+ simple firmware change



I have a Ultimaker 2+ which I love. I have had some success with uploading a version of Marlin to it so that I can change the Serial Port to #2 and baud rate so that I can attach an ESP to J22 (Serial).


This worked well, as I can now see GCODE output etc, but the firmware I am using seems to run the feeder in reverse (ie material is pushed out of the printer instead of in) 


I was a bit worried that I was endangering the printer running with this firmware. Has any one got any experience of this, or could point me in the direction of settings I could change? 


What I would really like is just the bog standard firmware that I can adjust the two settings in, but there seems to be a whole minefield of different options now.  Tinker firmware?


Thanks for your time.

      • 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
