Rostock Max drop in Spool Scale

thingiverse

Dec 29, 2016 -- All printed parts and spool holder end worked out perfectly, but I realized the design has a major flaw - it can show different weights depending on where the spool sits on the spindle. To fix this issue, I need to come up with a new design. If anyone has any ideas, please share them. Dec 16, 2016 -- Time for an update! I printed all the parts today and assembled them, but I'm missing some screws and one of the holes on the big piece is in the wrong spot. Whoops! So, don't print it as is - it won't work correctly. A few days ago, I started figuring out the screen and made some progress, but haven't modified Smokinpuppy's code yet. However, I have some plans for the code, so it will function differently. I also designed a face plate tonight (in yellow) to house the screen and buttons. I updated my Solidworks files, but it's still not complete. The faceplate is just floating there, not mounted, and the buttons are floating too. There's no actual button to activate the switch yet, and no mounting for the Arduino or HX711 bridge. Also, the render config is not exact - the uprights for the spindle mount are rotated 180 degrees, so they stick forward instead of back like in the picture. Also, I have the EZStruder, not the EZRStruder. Close enough! Dec 11, 2016 -- I finalized the design a bit more and printed one piece, then started another, but my hotend started jamming (it's been doing it for two months). After getting tired of it, I completely tore it apart... Come to find out, my Bowden tube wasn't going all the way into the heat brake. I need to pick up some new ferrules from my shop before I can reassemble and hopefully get rid of this jamming problem. Complete WIP - Just figured I'd post it now to have some ambition to actually finish it. Supplies: Arduino Uno (or clone) 5kg weight sensor beam thing (see remixed from or exact one) Amplifier for the weight sensor (again, see remixed from) A screen. I was going to use the one used in the others, but I realized the one I ordered didn't come with the I2C bridge thingy, so I ordered a $1 one from China... However, I ordered this: https://www.amazon.com/gp/product/B01HHOETIA, and plan to try and make it work. It will fit my Printer better too, as I plan to put the screen right in the front flat part on the Rostock Max. The others wouldn't fit with my extruder mounted there. 2 M5-10mm (approx) screws 2 M4-10mm (approx) screws 2 Self Tapping M3 screws, 6mm long or so. After disassembling plenty of computers, I have lots of spare screws from those, I think they are self tapping M3 or similar. Or maybe they are 2.9mm self tapping. I don't know.
