UM2go+ Feeder

Want to turn your 2go into a top-of-the-line 2go+? With this easy-to-assemble housing and inner parts from a UM2+ feeder, you can do just that. To get started, you'll need to assemble the feeder, which is simple with the UM2+ upgrade kit (ultimaker.com/en/products/extrusion-upgrade-kit). This will not only upgrade your whole 2go but also give you access to the feeder parts from the + kit. You can then remove these parts and install them into this printed housing. Or, if you prefer, you can buy the parts listed below from your local Ultimaker supplier. The design is perfect for fitting into the 2go carry case, although it may be a tight squeeze and might require some gentle persuasion. Two parts do require support, but don't worry – I'm working on fixing that issue. Additionally, the feeder is only held in place by three stepper drive screws, which I'm also looking to rectify. The main body features a clever tower design that prevents overheating of the shaft for the Feeder Lever during the final stages of assembly. To get this upgrade working with your default firmware, you'll need to reverse the stepper motor wires. This can be done by pushing in the tabs on the plugs and gently pulling out the wires. You'll also need to change the E steps from 282 to 738 if using the original feeder or 369 if using the 2+ feeder. This adjustment can be made in Tinkergnome's firmware, which is linked below. If you're using the original feeder, you'll need to trim the length of the stepper shaft down from 22mm to 13mm so it fits properly. This is the same length as the 2+ stepper shaft. To complete your UM2go+ upgrade, I highly recommend getting the heated bed upgrade from Gr5store (thegr5store.com/store/index.php/um/heated-bed-kit-for-um2go.html) to unlock full material capabilities and Tinkergnome's firmware for UM2go (github.com/TinkerGnome/Ultimaker2Marlin/releases), which adds the heated bed in the firmware and allows you to adjust the feeder E steps.
