Review: Great for modifying a Neptune 3 Pro. - The Neptune 3 Pro comes with automatic heightmap creation, but no actual bed leveling; it's all fixed in software. This actually works really well for most people, but once you start using Klipper and then get into more advanced setups, you may find yourself wishing you could adjust the bed a bit yourself. This worked extremely well on the N3P. I did have to drill out a few holes, but outside of that it connects with ease and I now have manual bed leveling. It even comes with two different sets of springs, so you can pick the best one for your printer. This is a very, very easy modification that can be a huge improvement.
Review: Very happy with the purchase. - Amazing product, the quality built to last, works really good, and the price is very reasonable, very happy with the purchase.
