Re: Filastruder Documentation and CAD/STL files

So I made a new version of the hopper funnel. I didn't like how it fitted to the hopper and how thin the whole structure was. This version has thicker walls to match the strength of the hopper. It also has a recess and lip to hold the hopper firmly and give you a solid glue surface. I also curved the inside and top edge to keep the pellets flowing downward with gravity. You can print it with no support structure and remove the one I put in when your done. All of the external measurements are still the same.

This forum won't let me post links but go over to thingiverse and look for item 82611.

Re: Filastruder Documentation and CAD/STL files

Hi Tim,

When I loaded the Kickstarter Hopper v5 STL into Slic3r, it generated G-code to print it upside-down.  Any chance of saving an STL that is flipped?

Thanks, and thank you for creating this wonderful machine.

Whoopsies. I'll fix it.

Also, it's a good idea not to download anything until you kit arrives, in case there are improvements made along the way!

Re: Filastruder Documentation and CAD/STL files

Do you recommend printing the 3d models with PLA or ABS?

Is there a way of getting the wooden case in the Kickstarter video?

I've always printed them in ABS. The only part that might not work well in PLA is the hopper. The steel barrel is about 65C at the hopper while extruding ABS.

OS Printing plans on releasing the wooden case files at the end of May - I'm a little ahead of schedule shipping. smile

If anyone missed it, Tim has uploaded the build video http://www.youtube.com/watch?v=4ek03ugI … e=youtu.be

Re: Filastruder Documentation and CAD/STL files

Thanks Tim.

What type/percentage of infill should the 3d parts be printed at?

11

Re: Filastruder Documentation and CAD/STL files

I usually print at 80% line, but anything over 50% is probably fine.

Re: Filastruder Documentation and CAD/STL files

Is it important that the wood platform be exactly 22 inches long?

The piece of wood I bought is 1x6x24 inches at (Poplar, Lowes, $5).

13

Re: Filastruder Documentation and CAD/STL files

That should be fine, though they'll cut it for free. smile

You might want to place the motor mount an inch or two from the edge of the board, instead of on the edge like the video.

Re: Filastruder Documentation and CAD/STL files

I just finished a laser cut case for my kit.
For those who have access to a laser cutter and got the kit here you go.

Seriously impressive! Thanks!

Re: Filastruder Documentation and CAD/STL files

what about how to fix the thermocoupler in Ks messages,are you going to upgrade the instructions iam really lost to understand how to fix it.

great job drandolph.

How to fix it? You mean attach it?

There should be a hole in the side of the nozzle, just slide the probe in and tape it in place with Kapton tape.

Re: Filastruder Documentation and CAD/STL files

yes attach it !! sorry i been translate the instructions and some things and technical expressions dont make so much sense after pass true the google translator.....
thank you Tim.

Re: Filastruder Documentation and CAD/STL files

Is it more important to get the pipe as tight as possible or to get the cut out facing straight up?

20

Re: Filastruder Documentation and CAD/STL files

Get it as tight as possible without the cutout being turned more than 45 degrees from vertical. If it gets turned more, pull the 4 bolts out and rotate the assembly 90 degrees.

Re: Filastruder Documentation and CAD/STL files

Does the thermocouple need to be insulated from the brass nozzle?

Would you recommend covering the fiberglass insulation with aluminum foil to contain the heat?

22

Re: Filastruder Documentation and CAD/STL files

Nope, definitely don't insulate it or it won't get a accurate temperature! The teflon insulation is good to 250C or so.

You can cover the insulation with foil if you want, but since foil is a great conductor it won't do much to contain heat...

Re: Filastruder Documentation and CAD/STL files

Thanks, Tim.

Do you have any instructions for using/tuning the temperature controller?

You might want to auto tune it - instructions are in the "Lessons learned so far" section. There should have been instructions in the box for the controller also.

Re: Filastruder Documentation and CAD/STL files

I was able to get it working.

PV = Present value
SV = Set value
hysteresis = dependence on a system not only on its current environment but also it's past environment
PID = Proportional, Integral, Derivative
TC = thermocouple

The alarm value needs to be changed from 100 to 180 in order to get SV to reach PV 180.

The temperature inside the filament hole was measured to be around 188 degrees C using a digital thermometer with the same type of thermocouple.  That was after setting the temperature to 180 degrees C using the PID.  I guess I'll fill in the thermocouple hole with RTV silicone ($3 on harbor freight) to prevent air from getting in.

Which direction should the shaft be rotating with the perspective of motor on the right side?
