BLV打印頭使用Zesty Nimble和Zesty Kryo，帶BLTouch

I am in the process of building the awesome BLV MGN Cube, but am planning on using the Zesty nimble direct drive extruder with their Kryo water-cooled heat sink (vertical orientation). I will also be using a BLTouch for the autoleveling, so this is a fairly specific "thing". Maybe it'll help someone that is doing a variant of this, and can use the components in their design. BLV MGN Cube - UPDATE - AUG 11, 2019 - I have done a revised veion 2 of this that is the one I built for myself, and I think is a bit more balanced. This one works fine, and looks more like the original BLV design, but I wanted to let anyone following this project to know of the updated one. [UPDATE - July 10, 2019] - about 90% there - I still have to complete the front grille and final attachments of the cover and belts, so this update while academic, has all the main components fleshed out before I do a printed mock-up to make final tweaks. I plan on being done by end of next week. The main changes are that I worked out how to keep the final nozzle location within .14mm of the original design that was using the E3D v6 head, and also keep the BlTouch offsets per Ben's original design in the same exact place. This mea in the end, very little if any changes to the config.h file will be needed (one of the goals of this). It also incorporates Ben's beta design idea of two 4010 blowe to cool the extrusion, and managed to do that and make the overall depth even closer to the rail than the original. One last item that I plan on including is a patch board to aid in wiring. That will be a last minute surprise, and uses an existing part from the wanhao i3 plus printe - fairly ubiquitous and easy to get. [UPDATE - July 16, 2019] I finished the final draft of the design, and will be mocking it up next week. All the parts are now more or less done, and I'll be fine-tuning if necessary when I print and check clearances. I will also be doing two additional parts as the final publication: a blank front cover template so that people can modify the front cover to do any design they wish. a modification that will incorporate a bottom rail guide, which will be a peonal modification I will be implementing on my BLV Cube, so there's less moment force on the top rail, and help mitigate the eccentricity on that part. Misumi offe a milled parallel extrusion for a minor upcharge, and that will allow for a second bottom rail guide without any worry for stiction or binding. [UPDATE - July 17, 2019] Forgot to include the cage file. Also updated to reflect some of the things I've remixed into the full design. The clip support will be a merger of the loom connector and PTFE tube support to the Nimble into one, and added in the next day or so. Last item I'll be adding before full mockup is the electronics patch board and support for those that want a clean way to do the wiring at the printhead. [UPDATE - July 23, 2019] - Last update before formal publication. LOTS OF CHANGES. I printed up the mockup, and made tweaks CHANGE(S) - I went to a single part cooler, namely since I didn't like the direction it was going in terms of mass and weight for a fractional benefit - I came across a "tusk cooler" that I believe is far superior to a two fan setup, and used that in a remix. This reduced complexity of the build and significantly reduced slung mass and lowered weight. The final publication will include the remix's hole drilling jig to help with making the proper holes in the 4mm OD aluminum tubes. I recommend the "cinched end" approach to the tubes to close them, and properly done, you can use the flattened end to align the holes, if you cinch the end in the same plane as the drilled orfices. I also changed the routing of the water lines for better access to the loom back to the control area. I’m also adding a couple of shots of the early mock-up. [UPDATE - July 25, 2019] - I've finalized the project, since I've printed everything and assembled it to check for fit. Works well! I also worked out a patchboard to go with the back plate, so you can mount a patch panel to clean up wiring. The intent is to have one, preferably two of the patch boards made at any number of inexpeive on-line PCB prototyping sites, solder on the header, JST connecto, and a 20 pin IDC connector. Then you use a round to flat ribbon cable to carry the power and signals in a neat manner to the electronics. You shouldn’t have to unzip the file; most places use the zipped file. i am including a picture of the board layout as well, since that I can attach. If you're in the US, I highly recommend using to make the boards. For $7.35 (their min cost), you get THREE boards. [UPDATE - July 26, 2019] - Ok, I came across a minor thing I had to tweak - the and the back . Those two files are new as of today. [UPDATE - July 31, 2019] _ I received a production Kryo and was able to test fit it. I modified slightly the front and back carriage stl files to allow for better fitment. [UPDATE - August 22, 2019] _ I fixed a small problem with the patchboard that prevented the JST-XH heade from fitting.
