The fan is polished, and the ABL have been added. I'm working on a new project that is related to this one but improved. New updates are coming.
Update 01/31/2019: I was asked by a user to add some lower holders for the people who have a problem with the height. I left the original for everyone else, and I add it 1mm and 2mm lower in case some hotends can't reach the bed.
Update 01/16/2019: The parts are better polish for printing use, and I add it a bltouch for bed leveling. The tutorial for bltouch is going to be in the at the end of the instructable. You can use the Volcano extender for the Volcano hotend if you want to print faster volumes.
Update 8/18/2018: I changed the hanger and added it bltouch fan closer to the hot end in order to make the bltouch work check my instructable for guidance.
Update 5/08/2018: I add it a go pro mount to the fans. The reason I made this is not meant for recording, but as a more precise way to check if the printer is printing correctly. Now I am able to see the tip and see if the nozzle is printing and a camera from far away will tell me a few hours later when there's a gap or a problem.
Note: This part can be used for anything that you want, you can make your own part for this section.
Update 4/09/18: I made some changes to the extruder, I made the hotends a little closer (22.79 mm to be exact, make sure you change the firmware setting) and I move the tool 0 to the original location as the CR-10. This way you have one nozzle that is able to reach each end of the bed, now you will not have to worry about leaving some space around the edge.
Update 4/2/18: Hi everyone, I was able to add a tutorial with hardware and software for the upgrade. Please check it out and ask some questions.
I decide it to show my idea of a dual V6 extruder. The way I was able to put two of them without having a problem with the nozzle hight was a screw. The screw controls the rotary movement of the nozzle holder and allows to have a precise hight between the two nozzles.
Please be kind to leave a message if you have any ideas for improvement.
-Try to print the highest resolution, that way the rotary system works better.
-Thanks to the screw you are able to rotate with a higher precision.
The distance between hot ends tip is 30 mm.
