Flex3Drive Dual mount for d-bot

thingiverse

Human: A fusion of the D-Bot's E3D hot end carriage side bracket and a simple U-shaped bracket to hold one of the exceptional Flex3Drive Dual remote direct drive units is being experimented with. The first version without a BLTouch mount worked perfectly, but issues arose with a 330x330 bed D-Bot and leveling, and occasionally cooling parts hitting the top of the z-screws. The second version saw the flex3drive mount raised by 10mm as it provided more Z movement, and meant my cooling wasn't going to hit the top of the Z screws. A BLTouch was also added. In Klipper, a z_offset of 0.38mm is used, and when a thick sheet of paper is slid underneath the nozzles they grab just a little. First layers go down like a dream. Currently, a part printed in PLA at 80% infill with 5 perimeters is being used, and it seems to be strong enough. No ringing or other artifacts are seen when printing as fast as 100mm/s. A PETG test print also produced a very strong part but I've not mounted it. The easiest way to build this together is to mount the BLTouch, cable on the outside first. Then, the piece onto the D-Bot carriage. Next, assemble the flex3drive, with hot ends mounted and aligned. Slide the assembled extruder/hotend setup onto the mount. Do up the screws holding the flex3drive in place. Confirm z_offset for the BLTouch however your firmware of choice does it. For heat sink cooling, two E3D cooling fans turned out a little have been clipped on. Other approaches are being thought through which will be experimented with another time. Have a look at keales' The Diablo for extra components that'll help keep your setup neat. I like to see good ideas succeed, so go check out Flex3Drive.com for more information on the product itself.
