    This upgrade was super simple to do, looks great and works great. I coupled this upgrade with the TAZ X Axis Linear Rail upgrade from Itworks3D and It WORKS! Great! Customer support is also super and quick to respond!

    ABSOLUTELY AMAZING! My Taz 6 hasn’t printed this nice since I bought it new when it came out! This is an absolute must have upgrade and if you have any questions their customer support goes above and beyond to help. Next I’ll get the X axis upgrade!

    I don’t know why I waited so long for this linear rail upgrade. I’ve always noted a little bit of flex in the build plate – but NO MORE. This upgrade makes the bed an absolutely solid foundation. Easy to clean, and honestly, easier than I thought to install. Instructions were very clear. I was admittedly nervous drilling into the build plate and end plate, but the drill guides were spot-on.

    Note: I own a Taz 5, so my stock rubber feet didn’t work with the design. I imagine the stock Taz6 feet are what the legs that get replaced are designed around. So adding new feet from openbuilds created a bit of a height different (lifting the Y axis) about 3 or 4 mm higher than it previously settled on the main gantry frame. (The reason is because they sit flush with the foot, and did not fit into the embedded design. So there is a gap about 3-4mm under those feet.) HOWEVER, there’s an easy garage solution: I added 2 washers under each rubber foot on the main gantry, which lifted the rest of the printer to match the height of the Y axis.

    I also got the X-axis linear rail and highly recommend them together. I feel like I have breathed new life into my 7 year old printer.
