how do I put this extruder together?
April 08, 2015 03:05PM
I have this extruder:
[www.mijnalbum.nl]
[www.mijnalbum.nl]
how do I do it with that Teflon hose/tubing and that black clamp ring?
[www.mijnalbum.nl]
Look also a moment to the Attachment?
the top of the red plastic of the extruder is flat,
but the aluminum extruder with the teflon tube and the black clamp ring is not flat!
shall I cut on the green line? (Look to the Attachment please?)
if I do cut it
there be still remains a part of the black clamping ring behind in the extruder!

I hope the Google translate was successful?
Best regards from the Netherlands (Rotterdam)

okay thank you all for the reactions,
it will probably be solved now!winking smiley

Bye!

That seems to be a standard Prusa i3 Rework extruder, but with an E3D hotend with a Bowden fitting i.e. wrong model. The teflon tube should not be used in this case. You can find more instructions for assembling the extruder itself in the wiki or online (search "i3 Rework assembly").

More help would require more specific questions and more pictures.

Hello Andrew,
okay wrong model I understand!
.
but in order to fix it?
as I cut the teflon tube
tube equal to the top of the aluminum,
and then I slide it into the plastic slot?
cut at the height of the green line (look to the Attachment?)

Hi Rob,
Yes, that is exactly what you should do, or use the non-Bowden model of the E3D. But I guess either way should work.
Re: how do I put this extruder together?
April 11, 2015 02:48AM
okay Andrew,
I know enough thank you!
it is actually not the way to do it like this i know
but I want to try it,
is important that the holes are centered (in-line)
and I think I should put the teflon tube in
and I must therefore ensure that the top of the holes are centered
( equally placed )

[reprapworld.com]

when I put the extruder in place
I look in through the plastic
then the holes are just right
So that looks good

Andrew thanks for now
best regards
Rob.

There's only 1 type of E3D 1.75 .....Universal
IF you insert the black part it will retain a PTFE tube for a remote extruder bowden set up
IF you remove it the hotend is suitable for direct drive
I wouldn't cut off the black part as the remaining bits may cause problems later . You can remove it with a bit of care & force. Easy to replace if you damage it.

Once removed insert the PTFE tube into the hotend and make sure it goes all the way into the heat break. I find turning it a bit while pushing it in helps to get it all the way down.
When its in place trim if flush with the top of the hotend with a sharp knife. USe a sharp knife so you dont deform the PTFE tube too much.
Its also a good idea to use a drill by hand and chamfer the hole of the pipe so its easy to feed in filament later.

Good luck

Yesssssss
also thank you Bigfilsing!
you will not believe it,
but was also planning the top of the tube witha drill to make an angle (A forerunner, may I call it that?)
I even was thinking about a sharp cutter!

Re: how do I put this extruder together?
April 11, 2015 10:01AM
Yeah that tool should work just dont go too deep and make the tube wall thickness to small ( wand dikkte te dun)

A good way to cut the PTFE pipe without crushing or deforming it is to put some filamant in it and cut around it if you see what i mean. then pull the filament out

No you cant call it a forerunner grinning smiley that doesnt translate from Dutch too well . There;s a few but probably a "lead in" would be best suited.

I used to live in Holland nearly 20 years ago and had a workshop in De VIerhavens straat In Rotterdam. Great place
If you get stuck with translation on this stuff just post again or PM me

thanks for your advice, I will do so!

Kind regards Rob.
Re: how do I put this extruder together?
April 11, 2015 11:01AM
based on what i saw in the vid

Unless youre using a dual extruder take out the E1 stepper driver and keep it as a spare. Other wise its just using power ( not much ) for nothing. Better to take it off and keep it for later use.
try and keep the auto fuses ( the big yellow things next to the power connector) tidy. They are quite easy to break
Don't forget to loop power though to the other power connector for a heated bed. Many have fogotten this then wondered why the heated bed doesnt work later smiling smiley

Looks like a nice tidy build ...good stuff
Re: how do I put this extruder together?
April 12, 2015 03:51AM
my first hobby electronics, so yes I know what I should do.smiling smiley
(but thanks good/fine that you point it out to methumbs up)
stepper driver:
yes I know, he is indeed too many!
I thought indeed that does not use many so put him there but just for temporary.
and also the fuse, I know what they are.(on the film one(1) fuse is skewed - the factory has done so)
also looping, I am indeed not done yet.
I was thinking to use a relay,
then goes the FET not so hot:
[www.youtube.com] (look on 0:38)
(FET switches the relay and relay switch the heat plate)

I will now and then show something here(photo/film)
or something to read.

I hope the translation still a little goes well ???

Bigfilsing, Andrew and everyone who read it
the friendly greetings from here!

The relay is a good idea as we all know the standard FET's aren't the best and most efficient.
I would recommend you look for an electronic relay rather than a standard automotive relay

Something like >> [www.ebay.com]

Good luck

HAHAHAAaaaa look at (2:05) :
[www.youtube.com]
yes it is the best way to do it!
.
the rest of the video is also interesting!thumbs up
I'm going to at one point later i think going to do
I will also make stability reinforcement brackets
for me it is very easy,
I am a professional metal worker.
.
but !!!
another question? (Software!)
what software can or can I use for the Prusa i3?
there is so much and I just stole my son's laptop
Marlin
Octoprint
Repetier

[www.3dprinter.nu]

Re: how do I put this extruder together?
April 12, 2015 08:03AM
Ok
Octoprint doesnt actually control the printer as such. It allows you to control it via a network web interface
Take a look at >> [www.youtube.com]
( nearly all of Toms video are worth a watch )
i have it installed on a Rasberry PI and its great for stand alone printing i,e, without a computer attached. You can also achieve stand alone operation with an LCD panel and memory card.

Marlin & Repetier are types of firmware that you load onto you control board.

Judging by your previous video you have already loaded the Marlin test program so id stick with Marlin if i were you. I find repetier a little bit trickier to set up but maybe thats just me.
I think the forum and internet support is better for Marlin so to start out go with Marlin . Its easy to change and try other things later when you have your machine up and running.

As for modeling software. Thats a big question with many answers

I would say that as a metal worker you'd want software that create's and edits solids( Autodesk Inventor, Catia, Solid works) rather than meshes. (Rhino.3Dmax, Blender Sketch up)
A great piece of free software for solid parametric modeling is Design Spark from RS components.
All of the above can export STL's to 3Dprint

extruder not ready (not important for a moment)
.
I've been busy to make the printer work (software)
I did not do it!sad smiley did not work
Now I asked in a another forum
and they wrote that I should connect the *Thermistors*
and that I had not done yet!
I hope tomorrow to do this here and I hope that it can be moved
.
Thermistors
there goes my next question,
it may be that there are two different types of sensors/Thermistors to be used?
that that of the bed is different from the extruder?
and if so,
maybe you can also fooled the ramps?
by, for example, by placing the resistors of 100K in place of the Sensoors?

Greetings to you all!
Rob.

Re: how do I put this extruder together?
April 14, 2015 09:33PM
Yes, you can just wire two thermistors temporarily to the RAMPS and configure Marlin or Repetier for them, to test the electronics and the motors.
Re: how do I put this extruder together?
April 15, 2015 01:15AM
The issue is that the board protects itself when it cant read a temp for the hot end. So if its not reading a thermisistor on the hotend the firmware assumes cable break/defect thermisistor/ runaway temp.
IF you want to test the output for the heated bed its the same story.
You cant really use a fixed resistor as a substitute. It may work with a 100K potentionmeter where you could "set" the temperature reading and fool the ramps into thinking a thermisistor is attached but i think thats a lot
of work for little benifit.


you don't even need both to run tests on motors axis etc
just a single one for the end end will do
heres a pics of one that i made up to test ramps boards.

and dont forget you have to tell the ramps which type of thermistor you are using in your config.h file ...for both the hotend and the bed

HOOOWwwww
I was afraid, it will not become easier with it!
I have this PCB:
[www.mijnalbum.nl]
here it is also, scroll down please?:
[reprap.org]
but I also I have this:
(coincidentally the PCB and additional temprature censoors bought!)
[www.mijnalbum.nl]
the heat plate I had, and the sensor for the E3D V6.
that are thus two(2) different types of censors.
I have two(2) of everything now.
who sits on the board is 100K
the sensor which is on the E3D V6 (approximately) 30ohm (30R)
.
thank you again Bigfilsing and Andrew!
the software,
I must admit it is not getting any easier
brains of mine have trouble with it!eye popping smiley

Je maakt het niet makelijk voor jezelf eh spinning smiley sticking its tongue out

I think you might be trying to run before you can walk spinning smiley sticking its tongue out

Right so put the thermo couples to one side and consider it an upgrade for later !!!!
Use the standard thermistor that came with the E3D for the hotend . They work perfectly fine !!! Only much later when you are really fine tuning your prints could you possible get any benifit from a thermo couple ( and they are more electronics that need setting up and could go wrong ...KIS = Keep it simple ( at least to start with) )
I think the E3D comes with a Semitec 100K ohm thermistor last time i checked.(so "5" in config.h)
Or if its an older type it could be a Epcos ( which is "1" in config.h)

I cant really tell what kind of temp sensor is fitted to the heated bed but im guessing its a thermistor as well. If you know the type it is then set it in config.h.
Config.h draws reference from thermisistor tables so its important you get it set correctly ( the tables are the known deviance's of the most popular thermistors because the errors for thermistors isnt linear i,e. if its 2 deg wrong at 100C doesnt mean it will be 2 deg at 150 etc)
When it doubt set it as "1" in config and see if it works.
If you then power up the ramps and connect to it with pronterface you should get a temp reading ( room temperature as long as you haven't switched on hotend or heated bed of course)
Re: how do I put this extruder together?
April 16, 2015 02:57AM
inderdaad ik maak het mij zelf niet makkelijk inderdaad!

indeed not make me easy.

that is because the seller he came with the PCB it themselves,
(he says) you've actually still need some PCB to convert the signal,
and I thought the seller will know it! (he is the man with the knowledge!)

but!
I've been busy with it again.
I got it still not running,
I have here two kinds of sensors I have also connected the sensor from the heated bed and the extruder.

there is now a friend withhe has visited who knows a lot more from software,
but he got no movement also!
I (we) have been looking and looking into the software.
I'll get moving if I only test the Arduino software is put on,
but repetier host I get (we) it still running.
so sensors are connected but equally no movement.
I've been thinking I'm going to look to the limit switches,
just check, you never know, maybe there is a mistake there?

I must honestly say: it is difficult, but still exciting! smiling smiley

Re: how do I put this extruder together?

what are you running ? You havent mentioned it
Are you using pronterface to try and control it ??

The simplest solution is to load Marlin firmware then connect with pronterface

HO HO HOOOOOOOWWWWWwwwwwww hahahaaaa LOL
have been very happy, he moves!
still not 100% correct but I think that just yet problematic.
(the motors rotate only in one (1) direction)
and I believe that which can also come through the iend switches???
*with their pull-up / pull-down resistors*
I could be wrong! i do not know yet, but I have also discovered more INFO
So there I also need to get started to read.

HOOWWWwwww Bigfilsing
by exident I have downloaded : SPRINTER
that came through this video: [www.youtube.com]
That's because I just found out that my FIRMWARE
it just was not good on my PC.....in Arduino it was not in the Arduino software.

going down now ;-)

Re: how do I put this extruder together?
April 17, 2015 05:55AM
Not sure about sprinter or repetier but in Marlin you can only manually move the stepper axis away from the end stop until it has been homed for the first time since power on.

Which would explain why you can only move 1 way when you power on.

OK next step is to check end stops

Before powering on move you X and Y axis to mid point and your z to at least 50mm above the print bed . Then type a M119 command this should return your end stop status - Open if then are not touched & TRIGGERED if they are.

Hold them by hand one by one and issue the M119 command to check they are working
Re: how do I put this extruder together?
April 17, 2015 06:04PM
Unfortunately, I understand your story not so good!

What I do notice,
is that all of the directions of rotation that do the motors in the direction of the end stops.
it is that I will not allow, otherwise the switch would be pressed.
shall I will allow it for once? or will I press the switch by hand?
.
now I will probably should be ashamed of myself???
where do I write that code M119?
I think somewhere in the Arduino language / code.
to remember I'm not a profesor, I'm just a simple soul! ;-)
.
I had to go to work today, so was just out of the picture for a moment

And Bigfilsing yet again thanks again! thumbs up
Rob.
Re: how do I put this extruder together?
April 18, 2015 09:05AM
Ok first things first

M119 is gcode
Gcode is what controls the printer movements etc
Gcode is generated by slicer software ( like CUra for example) Cura takes your model ( an STL file) and together with settings you input like temprature layer height etc etc It generates Gcode to drive the printer.

The user can also type in gcode and send it to the printer in whats called a terminal window > this you can use to make adjustments to settings ...steps per mm for example but also "ask" the printer for status of things
M119 in effect request the current status of the endstops

The easiest way to start talking to your printer is with pronterface. A free download program that controls your printer for windows >>[koti.kapsi.fi]
Install that and then connect to your ramps board. Note you have to set the com port ( look in device manager which com port your printer is on) and the baud rate ( which is set in config.h)
when connected you will see the printer send back info in the terminal window of pronterface
at the bottom of that window is an input area where you can type in Gcode commands ( then hit enter or click "send" button on the left) and Marlin will report back
see pic below ( ignore what the text in the terminal window picture below says .... its from a different type of printer im building )



I think you need to do a lot more reading on the wiki pages and forums to understand all this stuff.
Unfortunately my written dutch isnt really good enough to write all this in dutch but im sure theres forums in NL for that.

So before you go any further stop messing around with Sprinter and repetier for the moment ( you can try them later ) get your printer running with standard Marlin and connect with pronterface.
That way you can easily test end stops /motor directions/ calibrate steps per mm etc etc. You know how to load Marlin test program so do the same with Marlin firmware.

Good luck

bigfilsing you do an excellent job!
and in the meantime I have done it.
everything goes up / down left / right, front / rear..... it works! spinning smiley sticking its tongue out
what I do is watch a lot of videos.
with search terms that I again read from people like you!
no professional videos but good enough for me:

the author of this video helped me to get the firmware in to the Arduino software (so now I can move everything!)
here a video with more clear explanation:

I have several types of software on my PC now.
Repetier Host - Printrun - sprinter master.
I think also to take marlin on my PC, it seems to be good???
