i have just uploaded some initial documentation and images of my UM2 modifications.
In case you are curious, you can take a look here: http://www.ibrieger.de/ultimaker2-3d-pr ... tions.html.
The main purpose of my modifications is printing more plastic per second since i mainly print functional and/or big parts - and i am impatient
.Things i have done so far (besides the usual mods like Olsson block, ballbearings for the filament roll, fan shrouds and so on) are:
- * A custom firmware
* A mainboard cooling fan
* A stronger feeder motor and a feeder motor cooling fan
* 1.75mm filament conversion
* Installed a flowrate sensor to limit printspeed if things get to fast for the feeder/extruder, and to measure Temperature-Flowrate curves.
