Long bowden tubes stink! This became even more apparent after installing a volcano clone heater block on my printer. You need precise control of the filament to keep blobbing under control. Try this experiment - print out one of the many manual extruder knobs here on Thingiverse and install it on your extruder. Make sure the filament is fully inserted in your nozzle, and cool down your hot end. Once it's cool and the filament is fully fused into your hot end, turn the extruder knob back and forth and see how much the filament can move at the extruder with no movement at the hot end. The longer your bowden tube, the worse this is. After searching through Thingiverse for a decent direct drive conversion for my CR-10 and not finding anything I liked, I decided to design my own. This fits on a stock CR-10 using the original style hot end (I'm using the Micro Swiss all metal hot end). My design goals were - Cost as near to zero dollars as possible, Easy and clean installation, A strong and solid mount, Clear view of the hot end during printing. To those with concerns about adding mass to the X axis carriage - I say this: On an i3 style printer, it doesn't matter! Even with the big full size Nema 17 motor on the X carriage, it still weighs less than the Y-axis - especially on a big printer like a CR-10. For comparison, my complete X-axis carriage assembly is 559g, a CR-10 glass plate alone is 1kg. Once you add in the heat bed, Y carriage, etc, it's easily 2kg. And to make matters worse, the bigger your print, the more mass your Y axis gets. Last I checked Cura 4.0 doesn't offer separate X and Y speed/acceleration/jerk settings, and definitely doesn't scale settings as the print increases in mass. If you're a speed junky, get a Core-XY or Delta printer.
