/diy/ - Do It Yourself

as a person who actually owns a core xy machine; you dont want a corexy.
you sacrifice extrusion for very accurate speed. you (should) have to have nice 2x resolution steppers, special drivers (tmc or the ones the beagle board kit uses), (should use) 24v to run those drivers with ANY torque, you require 32 bit boards (dual extrusion requires a fully powered duet for the corexyu you want (https://www.youtube.com/watch?v=mMRnG_n2i84)) you also want carbon rods for an optimal hypercube build or you'll wear down your expensive polymer bushings. dont even think about putting two hotends on there.
printing at insane speed should be left to the deltas, you want an Hbot from openbuilds or a standard system. flexing with a corexy is dumb, dont get a kit corexy.

thats a darwin/"cube" design, I love darwin designs, buy an ender5 and mod it to be IDEX
tool switching corexy is the current panultimate design due to the position of the motors allowing for a whole row of extrudes in typically unused space. there are no corexy prusas, he made the I3, a mendel clone and its fucking pathetic original wiki page calling it the model T of 3d printers https://reprap.org/wiki/Prusa_Mendel at its "i2" point (although china ruined the whole nameing scheme for iteration 3 prusa mendel)

you cant call an ulltimaker a standard Cartesian printer, the stepper motors are stationary due to the custom, expensive carriage system thats really hard to DIY.

actually it matters a lot, its a key weakness in the mendel design

here's our god explaining the history of reprap and hobbyist darwin options at the time https://www.youtube.com/watch?v=CUwS6S4aNCA
