<h2>IN PROGRESS: Many parts still need to be tested, designed, and uploaded</h2> <h2>Wanhao I3 / Maker Select Corexy Rebuild</h2> <h4><strong>Warning: This rebuild is not simple and cheap, and will take a lot of time. Read through <i>everything</i> below before deciding and purchasing parts.</strong></h4> <hr> <h3>The Benefits of this Rebuild</h3> - Strength: Frame made completely of aluminum extrusions gives much greater strength than the stock metal sheet frame. - Precision: MGN12 rails are much stiffer, and offer much more stability. Ball screws on z-axis allow for more precise bed movements. - Faster Prints: By only allowing the heavy bed to move in z, and extruder in x and y, print speed is greatly improved and ringing is largely reduced. Acceleration and jerk can therefore be increased. Higher torque motors will allow for faster prints as well. - Fits in a typical lack enclosure - Larger Print Volume: Not certain on exact size yet- ~330x330x240 - Easily modified- X Y and Z are easily increased, <h3>The Drawbacks of this Rebuild</h3> - Expensive: Total cost is around ~$300. - Many stock parts are unused: x, z, rods & leadscrews, bed, entire frame are unused. This is in order to turn this printer into a high-grade printer, so cheap stock parts were generally avoided and replaced. - Not easily assembled: A lot of brackets, screws, and parts - Stock board is most likely unable to run Corexy kinematics: I'm running a 32 bit mks board. <hr> <h3>BOM * means the part is from stock printer</h3> Will be adding links later <h4>Aluminum Extrusions(from Misumi)</h4> <h5>  2020</h5> - 6 x 30mm - 2 x 60mm - 2 x 350mm - 2 x 351mm - 4 x 400mm - 6 x 423mm - 2 x 463mm <h5>  2040</h5> - 2 x 60mm <h4>Rods</h4> <h5>  8mm Rods</h5> - 2 x 380mm <strong>*</strong> <h5>  12mm Rods</h5> - 1 x 400mm <h5>  Rod Clamps</h5> - 4 x SK8 - 2 x Igus WAS-12 <h4>Bearings</h4> - 1 x lm8luu <strong>*</strong> - 1 x Igus RJZM-08 <strong>*</strong> - 1 x Igus RJM09 <strong>*</strong> <h4>Motor Brackets and Screws: Highly recommend purchasing from TrimCraftAviationRC</h4> - Around 200 x M5 * 10mm
