Using the Ultipanel with RAMPS...

Recommended Posts

Seems the Ultipanel was designed for Ultimaker not a RAMPS 1.4 board. However the smaller dimension compared to the RepRapDiscount LCD allows it to be used in a tighter space, though this is not significant in most cases.

That said, in my case I need to use the Ultipanel (read: I found a sweet case that I want to use). I thought setting it up in Marlin would be straightforward, however if I used the #define Ultipanel, the display would beep and flash, and I think the code was intended for Ultimaker electronics.

How I got it (mostly) working: defining it as a RepRapDiscount controller got me halfway there. What I needed to do was disable KILL_PIN, otherwise the message 'KILLED' would be displayed at startup. What is now not working, is that it doesn't react when an SD card is inserted. I tested the same firmware with a RepRapDiscount, and in that case it does see an SD card inserted. So there obviously are some variables in Marlin that needs redefining. I'm just not sure which ones.

If you look at the schematics, you will find that the pin that the RepRap-panel uses for the kill-pin is defined as a 3.3V supply voltage on the UltiController.

The 3.3V supply is used to power the SD-card and level-shifter IC. To make stuff works, uncomment the killpin in your pins_RAMPS-file, and solder a wire from the 3.3V-pin on the Arduino to this pin. This will supply the UltiController with 3.3V for the SD-card and remove the kill-funktion.

I had some of the same issues I guess... I switched to a Rumba board, but could not get the UltimakerController to work with that no matter how I defined it en Marlin (best I could get was two lines of squares)...

So I bought a RepRap SmartController instead and got that to work easily... It is bigger though, so I kind of perfer my old Ultimaker Controller and its retro radio style box -_-

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
