   * Olsson block: The original Olsson block for 2.85mm diameter filament (same one as in the UM2+)
   * Extruder: 0.4mm brass extruder. Exchangeable for other sizes.
-  * Feeder exchanged by the [[https://www.youmagine.com/designs/yet-another-ultimaker-2-feeder|Yet another Ultimaker 2 Feeder]], which is based on [[https://www.youmagine.com/designs/alternative-um2-feeder-version-two|this one]] from |Robert|. The yoke arm was taking from the |Robert| design as the other one was too short and it was not applying enough force on the filament once the gear was switched to MK8. The snap-on-guide is not useful with the MK8 and makes a lot of friction, so I removed it.

-  * MK8 gear feeder. This replaces the knurled feeder gear from the original Ultimaker feeder. More info [[http://reprap.org/wiki/Drive-gear|here]]. Specifically I bought one used in Bernis Magnetic Feeder.

   * Firmware: TinkerGnome V17.10.1
-  * Current of E Axis motor was increased to 1300mA from 1250mA
+  * Current of E Axis motor was decreased to 1000mA as recommended by the Bondtech upgrade kit.
   * Fix: The Printer reported often an error on the temperature sensor of the heatbed. The cable connector on the heatbed was not soldered properly from the factory, making the pins have an intermittent connection. Alexis soldered them again and it got rid of the errors.
   * Door: official transparent front door.
