Very interesting! So the 2 9 pin LCD outputs get ran together to that DB25 serial port, then the extruder 1, 2 7, and x/y to the 4 large cutouts and the bed to one of the two smaller round holes? Very clean, I like it! Those fittings look very interesting too. I’ll have to order a few of them and see how they work with a smaller printer.
I’m going a bit of a different direction with the AO-10x upgrades. I’m treating it more like a computer chassis with a printer on top. I’m moving the power supply inside the lower box frame structure and putting the deckplates on this weekend. From there, the next step will be putting another 20mm extrusion under the deckplate similar to how the Y rail mounted, and using that to mount my controller inside the lower frame, relocating it from the gantry mount since it’s the old RAMPS 1.4. Should be plenty of room to upgrde to a different one in there too though if I ever go that route. The Y motor will also be inside at that point too. That will give me direct wire runs to the Y and Z motors, then I’ll run the bed cables and the X and hotend cables through some Igus Series 6 small cable chains (http://www.igus.com/iPro/iPro_01_0002_0002_USen.htm?c=US&l=en) to elemiinate the cable snag droop issue and run them back to the gantry posts.
For the LCD, i’m trying to pretty much emulate the way you have it mounted on the TAZ. I have a smaller, hopefully working one on the way that should be less of a hassle than that big beast one I never was able to get working without it beeping constantly at me. THe power button will get moved down to the new front cover plate with next to the lighting switch. An always on 120mm fan will cool the electronics box at that point. I’m definitly going to have to borrow that DB25 idea and a couple of those connector ideas from the new Taz build folder though. The Power and USB connections will be on the back plate.
Have you guys thought about putting any kind of extruder docking port on the X carriage? I’m thinking something similar along the lines of the Dell Latitude E-series docking connectors if I can find them somewhere. I think they have about 36 pins on them, so it wouldn’t really be a problem to have a docking socket on the X carriage and a Docking connector on either the single or Dual extruder module you wanted to fit to the X carriage to allow for really quick tool head swaps. A DB9 or DB15 connector might do the trick, but i’ve seen too many monitor pins folded over at work to really want to go that route if I can help it for a connection that is going to be ideally used quite often.(run the single extruder for a job, pull it and add the duals, pull them and replace it with the paste extruder, replace it with a single with a smaller nozzle, etc.) If you run across a connector that would work for something like that, let me know
Thanks for the update!
