printerfan 5 Posted October 23, 2014 in Ultimaker Upgrades What is the benefit to adding each of the upgrades to your Ultimaker Original: A. Knurled drive bolt kit (v3) B. Extruder drive upgrade C. Ulticontroller kit D. Hot end upgrade (v2) Also, are there 3rd party alternatives or printables that are considered better? Share this post Link to post Share on other sites
valcrow 144 Posted October 23, 2014 in Ultimaker Upgrades I believe all those upgrades are already included with the current UMO's from like a year ago on. Mine came with a V2 hotend, knurled bolt and extruder upgrade. Ulticontroller allows you to use SD cards to print untethered from your PC and controls the UM speed and tune settings from an knob and LCD. Otherwise you'll have to run it through USB.

printerfan 5 Posted October 23, 2014 in Ultimaker Upgrades I believe you are correct Valcrow, I ask because I am purchasing a used Ultimaker Original and wondering what upgrades are worth adding. Share this post Link to post Share on other sites
