Rostock Max drop in Spool Scale by Turpinator

Last crawled date: 3 years ago

Dec 29, 2016 -- Printed parts, everything on the spool holder end went as it should, however... I realized this design isnt the greatest as depending on where the spool sits on the spindle, it can show different weights. To get around this... Hmm... I dont know. Itd have to be a different design. If anyone has any thoughts, let me know.
Dec 16, 2016 -- Time for an update. Printed the parts today, and assembled, except im missing screws and one of the holes on the big piece was in the wrong spot. Whoops. So dont print as is. It wont work correctly. A few days ago I started figuring out the screen. I can write text to it, but havent actually made any modifications to smokinpuppy's code yet. However, I have some plans for the code, so it will most likely function a bit differently.I also started designing a face plate tonight (in yellow) to house the screen and buttons. Updated to current solidworks files, but still not complete. The faceplate is just floating there, not mounted, The buttons are again, floating. Theres no actual button to activate the button/switch yet. Also no mounting for the arduino or hx711 bridge. Also render config is not my exact, the uprights for the spindle mount is rotated 180º, so it sticks forward, rather than back like pictured. Also ive got the EZStruder, not the EZRStruder. Close enough.
Dec 11, 2016 -- Finalized design a bit more, printed one piece, then started another, only to have my hotend start jamming (its been doing it for the past 2 months). After getting tired of it, i completely tore it apart... Come to find my bowden tube wasnt going all the way into the heat brake. 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 id 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 didnt 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 wouldnt 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. idk.
