    My first ebike battery build, 12p10s for A2B Metro

    I heard from our service tech that 3d systems bought out one of the DIY fdm companies and is offering their system for sale. He told me that you have to assemble it yourself. I havent verified this. I had seen a rep pap type machine that had up to 4 heads so you could print in 3 colors and have...

    What you are ecperiencing is one of the disadvantages of the type of system you have. To get around this you can home the machine to the limit switches (assuming this is a repeatable home position) from this zero location you then find your fixture offset. I just write this number dowy (XYZ)...

    Problem here is that how do you drill the holes (it will take 2) so they are in reference to the pitch diameter of the sprocket. I havent seen the sprocket, but locating it from the pitch diameter or possibly the locating feature in the center of the spricket if it exists and is centered on the...
