UP Mini is brilliant well tuned ABS machine and for most people this conversion will bring more pain than benefit.
Reasons behind the conversion:
-
I had 4x other machines running Marlin and my slicer of choice was Cura.
-
I've started experimenting with PC-ABS and PC and wasn't 100% satisfied due to low bed/chamber temperatures for these materials.
Bed reaches only 60degree C max hence it's not regulated (it has some kind of temp sensing cutout diode soldered underneath - not familiar with this technology) If you want to install chamber heaters you will require to have separate controller etc - pain.
- Due to declining availability of UP replacement nozzles I had a plan to potentially upgrade this machine to more generic E3D offerings (potentially Titan Aqua)
So far I have replaced electronics with AliExpress BIQU KFB 2.0 board (space for additional mosfet board if going chamber heater route), moded bed to go over 60degree C and added thermistor - the rest is kept as stock as possible.
So far I've been unsuccessful:
-
Sensing hotend thermistor, it's not regular thermistor nor PT100 - so save some troubleshooting time I've simply strapped with capton tape regular NTC onto the heater block (temporary solution, for almost a year now :) )
-
Find a use case for UP front button and LED so it's not wired
-
Design LCD mount
