Ok cool..im in cooper city.

I have gotten some questions about the new Hexagon AO hot end. It has a shorter heat sink and a larger aluminum block, so the fan shrouds don't fit. Here is an experimental version of the shroud that should fit the Hexagon AO. I have not tested it. If you do, please let me know how it works. I have no idea if it will provide enough cooling for the smaller heat sink.

This version is for the Itty Bitty Double FLEX Extruder. I have also posted one for the Itty Bitty Double Extruder in the other thread.

Those are some very nice prints. Voodoo, it doesnt look like you are suffering nearly as much as some of us with z banding issues... Do you mind sharing what you might have done to remedy that, assuming you ever had it?
thanks

Thanks!

Honestly, never had the Z banding issue...my z rods are stock and yes, they wobble at the top a bit.. I dont try to constraint them. Just them be.
I did make sure my entire assembly was square from the very beginning and belts are tight. I used calipers to make sure that both extrudes for the X carriage we even at both ends, then tightened it all up.

I am having trouble uploading my pics but I have completed my extruder and have now completed my first non-calibration print. Things are working great. I have the wires routed for the left extruder out the front to fasten with the rest of the wires on the left side wire secure location. On the right the wires are coming out the side to attach on the right side wire secure position. I have some subtle calibration and slicing configuration work but all in all it is working as it should.

I have run into a strange situation though. At the end of the print only the second extruder turns off. I have tried several ways including special gcode in sli3er and looking for a fix in the firmware. If anyone has ran into this issue and have a fix, I would be very grateful.

C42 thank you for an amazing build and even more fantastic documentation.

Just wondering what material and settings "temp, speed, layer height" you guys are using to print out the extruder parts?

Thanks,
Chadd

Thanks for the info. How did your pulley gears turn out? I have printed a few up but don't have the belts to check the fit, are the belts the same pitch as the ones that come with the makerfarm kit?

Am using simplify3d and am having problem with extruder offset. How did you guys that encounter this problem fixed it. How did you found the correct number.
