Marlin Builder and default values as used / shipped

Recommended Posts

I am currently adding a heated bed to the Ultimaker (using the instructions from http://flashgamer.com/arduino/comments/adding-a-heated-build-platform-to-your-ultimaker.

I want to use the Marlin Builder (http://daid.eu/~daid/marlin_build/) for modifying the firmware, but i don't want to venture to far from the original presets that came with the Ultimaker.

But i was unable to find something like a "Ultimaker Default Profile" :-/

The bubble help on the Marlin Builder is ok, but there are several points where i am unsure, e.g:

-> Enable PID temperature control -> Kp: 22.2 Ki: 1.08 Kd: 114

But in the bubble help it says: 22.2/1.25/99 are good for the Ultimaker

? What machine are 22.2/1.08/114 good for then? Why is that pre-filled with these values?

-> Max feed rate X:250 Y: 250 Z: 5 E: 45

http://wiki.ultimaker.com/Marlin_firmware_for_the_Ultimaker says:

default: {X160, Y160, Z10, E500000}

500,000 vs 45!?

-> Enable UltiController (Enables the offical UltiController hardware. This will also enable SD card support)

But it doesn't preselect "Enable SD card support" below. Will there be an error if both boxes are checked?

And "Enable UltiPanel" - is different from UltiController?

I understand that the Marlin Builder is a very flexible tool which supports many different kinds of hardware and modifications. But it would be nice to have some kind of "Ultimaker Baseline" which is documented and official.

Because with every difference between platforms, troubleshooting becomes more (and unnecessary) complex.

So, anyone got a 1.5.6 electronics current Ultimaker Marlin Builder dataset for me? :-)

The defaults of the builder are good.

About the PID: The tooltip is older, the new settings work better.

About the max feedrates: It's a bit of a preference, normally you never hit the max feedrate of 45 (45mm per second of filament extrusion?!?). But some people prefer "unlimited" which is the 500k.

The UltiController (as produced from the shop by Ultimaker) and the UltiPanel (beta versions, and version on thingiverse) are slightly different in how the rotation knob is wired. Other then that they are the same. The main difference is that the menus will rotate the wrong way around if you use the wrong panel type.

If you enable the UltiController or UltiPanel, then the "Enable SD support" checkbox no longer matters, it's always compiled with SD support.

The firmware shipped with Cura is build with the Marlin builder, at a point where Marlin was very stable. This firmware was build with the defaults of the builder, except that I also turned the UltiController on.

I also tested that firmware for 3 weeks before I shipped it in Cura. And many people are using this exact firmware now.

The Marlin builder is currently running newer firmware then that, with a few new features like long-filename support. So there is the potential of problems, but so far it has been running stable on my machine.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
