I desided to make an exctruder for 3d printing.
Yep, sir !
Just started )
@marypro Awesome 🙂
Just as a tip, make sure to spend as much time as needed removing that black paint from your auger bit, you can use a dremel or a steel brush. Don’t use the auger bit like that or the black paint will start to peel of when you start extruding and it will get stuck on your filament.
Wow ! Many thanks ! I’ll do that.
I do fill care here ).
Done. Black paint removed. Hope that it is enough.
hello I would like to know based exactly on the extruder, of this video of Dave, where to buy all the pieces, and indicate if possible European Union, thanks
You could tell me how are the measures of this please
The progress so fare:
Tail is ready, face too )
The screwdriver will be in the role of the motor:
I have found most of stuff on the local flea market.
L298s are great for controlling small motors, but may not be the best choice for this, the L298 can drive up to 4 amps, but your drill may draw up to 100A full load (test it with an ammeter). Your drill will already have a suitable MOSFET in it, probably conveniently located on a separate small aluminium heatsink, usually behind the motor. You can hook up a PWM drive signal directly to this, such as from your 3D printer fan driver board, but be aware the MOSFET in the drill won’t be a logic-level type, so the gate drive will need to be at least 7-10V. If the driver board has an output for a heated bed, this might provide enough power to run the drill directly, though the PWM frequency might be too low for a motor, and perhaps you already thought to use this to control the band heaters?
Obtained heating stuff
making holes for heating cartridges:
4 holes are ready — for 4 cartridges — 40W * 4 — 160 W. May be not enough for that extruder, but enough for printer’s power supply. If needed more — will create one more heating barrel with power from another power supply.
Tests are near).
When I saw your cartridges I thought they were a bit on the small side. You could try wrapping the whole barrel with fibreglass insulating tape.
Now what I need — is to create a spool coiler, because now I can’t get the strait filament — no space before the floor.
The filament width for now is 1.5mm and that’s OK for now — I am going to that that with my printer.
That’s ingenious! I love it!!
