So I got the upgrade kit but there is no instructions on how to install it
one of the "pillars" snapped when I was installing it and a few springs launched into what I can only imagine is another dimension is there anyway to print the B+ and or buy replacement springs
Here's a quick picture to show how it goes together. It's very similar to the older design, but that the new sliders allow you to swap out the bearing carriers with ones with more or less tension as well as more or less pre-loading. Here is the Tinkercad file with all the various designs.
Using the ones towards the top right give you a lot more tension... using the ones on the lower left, give you less. The default ones shipped with your kits are the ones in the middle.
If you're using it as an extruder, move to the top right area... if you're using it to just load and unload your existing extruder, the default carriers will work just fine.
