Yep that'll do it.

Interestingly I had a set of those same calipers which used to read wrong, might be worth measuring something of a known size. Just to be sure. I only realised when I bought a set of fancy 300mm ones and they measured the same object differently.

I've found them to be reasonably close, certainly good enough for this sort of work.

On this filament, you can try pushing it down the heatsink and it just gets stuck, cut off a metre, and the next bit goes down just fine. This is borne out by filament diameter measurements. The filament just has inconsistent diameter. You can print fine for half a print, and it will fail. Use the same file and it will fail randomly throughout the print.

It has taken me literally over a year to figure out this problem. Buying the Titan was an attempt to get more success with this filament. *sigh*

I've no experience with flexibles but that sounds like a PITA.

Just an update (and correction) turns out my steps/mm have had to change quite substantially moving over to this cloned extruder. I am now using 470 steps/mm with a 1.8 deg motor.
There is a bit of background to this, I think I had an early version of the titan which had the incorrectly made hobbed drive gear. My steps/mm were 333 before, which was a lot lower than the e3d recommendation of 420. However it was printing really well.

What I can't work out is that the genuine e3d drive gear has a diameter of 7.75mm the new one has diameter 7.35mm. This does not account for the huge discrepancy in steps/mm it should be just 5% change. The only thing I can't think of contributing to it, aside from the difference in overall diameter, is that the teeth are much sharper on the genuine titan drive gear, perhaps they were cutting into the filament a lot more than I could see. But thinking out loud that would suggest needing a lot more steps/mm on the genuine one as it would have a smaller effective diameter. Puzzled but not really bothered since both work.

DjDemonD, are you using the clone titan from triangle lab with genuine e3d v6 via direct drive? or Bowden? I read on the aliexpress feedback page that the clone e3d titan does not fit the genuine e3d v6 via direct drive.

Hi I am using it via bowden (flying extruder so quite short tube).

However I've been designing piezo hotend sensor modules which are groovemount adaptors and I have been testing them by fitting them into genuine titan and clone titan extruders and I cannot say I can see a big difference in the fit.

They are a very close copy, logically it would seem ridiculous if you couldn't insert a groovemount hotend into the extruder, that would render it quite useless for around half it intended users. I suspect a degree of spin here to discourage purchase of the clone.

I will try to remember when I get home to look very closely at the groovemount in the two extruders and tell you if I can see a difference. The only thing, and I mentioned it in the review, is that the filament guide tube in the clone would only line up with the bowden adaptor if it was pulled slightly out from the position it would sit normally within the genuine extruder, so at assembly ensure you can pass filament down the guide tube and into the hotend.

any one got the tech drawing and dimension of the V6 and V5, just checked the v4&5 they dont fit a clone titan. nor does a Jhead mkvb. but a $5 clone v6 does so it aint the end of the world smoking smiley



the top groove reported as 3.7 mm for v5/v6 yet the v5 here measuring closer to 4mm, the grove on the titan clone closer to 3.8mm and the v6 clone top grove come in as 3.60 why they fit!!
now my dodgy cheap calipers could be lying to me but you have to risk breaking titan to mount a genuine e3d if the groove is closer to 4mm rather than the 3.7 on the drawing.

I will definitely stick a genuine v6 and a cloned v6 into each extruder tonight and let you know. Even if there is 0.3mm in it that to me is well within sandpaper/dremel/warding file range to adjust. If you over adjust it you can always shim it, which you have to do with most groovemounts to get them stable anyway.

My piezo module is printed in PETG and the flange at the top is deliberately slightly too wide (in x/y dimension) so you have to (just about) force it in, as I want it to be universally a tight fit in all groovemounts where end users will install it, the PETG gives just enough to get a tight fit.

Re: Cloned titan extruder review/opinion...

Okay so I tried a few things for you:

Clone V6 into clone titan - good fit.
Clone v6 into genuine titan - fits but slightly loose
Clone v5 into clone titan - doesn't fit, the flange seems too wide in x/y and too thick in z.
CLone v5 into genuine titan - same problem too tight.

I presume a genuine v6 fits into a genuine titan properly so I also presume that a genuine v6 will be tight in the cloned titan.
I do have a genuine v6 but its installed and in use. I do not have a clone genuine v5 to try.

Wow... looks like i am going to have some issues to fit my geunine e3d v6 on the clone titan then.

Well depends on whether you expect everything to just snap together or recognise that some things need a bit of filing. Its like aftermarket car parts, they rarely fit perfectly, but they cost a lot less. You pays your money and takes your choice.

Can you confirm that the E3D clamp is just an adapter inside the Titan? Can't this be replaced by a printed one that fit's cloned- or V5- heatsinks?
Re: Cloned titan extruder review/opinion...

No the part of the titan (or clone) into which the hotend fits is the injection moulded back case of the titan extruder. So if you want to fit a v5 clone (and possibly a genuine v5) into a titan you'll need to file down the height and width of the flange on the top of the hotend.

There is an adaptor which fits into the groove mount in the titan case which is the bowden adaptor for 1.75mm filament. You could print one of these but that isn't going to get your v5 hotend mounted. You could have a 2cm bowden tube which for all intents and purposes is still a direct extruder.

You could try printing the back case for a titan with a slightly more generous groove mount but I'd be surprised if it was strong enough, and taking a file to a $10 hotend is kit a problem.

I got a cloned Titan and Volcano on the Tevo Little Monster Delta and it clogged up the third print. i had planned on replacing them anyway so I know have originals of both and here are my observations.

TItan
- Teeth on the hobbled gear not done as well
- Does not have the newer thumb wheel tension setting
- Bolts very light compared with the E3D ones
- Some variations in case design

Volcano
- uses older style thermistor mount
- machining not as well done

It's a workable system but overall it took more tinkering to get running and failed on me quickly. Whatever you do don't make it have to,push too much pressure, it will clog on you and grind up the filament.

In my opinion it's worth the extra to get the E3D parts.
Re: Cloned titan extruder review/opinion...

I have clone volcano (big tree tech) and it's been rock solid had it for 8 months. I don't print much pla so that probably helps. Bought it to try volcano before buying genuine e3d which I intended to do when it started to fail but it just hasn't.

Haven't seen any issues so far with cloned titan but it's early days and the cost differential is less from the genuine to the clone compared to a clone vs genuine hotend. So the equation in favour of the clone is less tempting for the extruder especially if you are somewhere where shipping is reasonable.

@DjDemonD, where did u get your clone titan btw? Trianglelab?

I just got mine from them, the e3d v6 genuine fits a little snug but it's okay. the only complain I have is the black filament guide above the v6 is too short. It has a 2mm gap betwen the hobb and idler. I don't believe that is good for flexible filament.
Re: Cloned titan extruder review/opinion...
April 10, 2017 10:54PM
Yes they're trianglelab ones. I will check the filament guide, see what the gap is. I agree it would be problematic for flexible if it were 2mm, (but I don't print any flexible so thanks for pointing this out).

May i know what steps/mm are u using for trianglelab ones? If I use 837 like on the titan assembly wiki. my extruder push less than what it is suppose to
Re: Cloned titan extruder review/opinion...
April 16, 2017 12:39AM
I'm using 400 with 1.8deg motors on the trianglelab titan, I only use 330 on the genuine titan. Which is much less than the recommended but objects print well.

I think the pressure from the idler has to be just right or you get quite varying results.

I can see why some extruders are now made with fixed tension even if there is an argument for and against it.

Fixed idler tension would still lead to different results with different filament. Even ABS from different brands can vary.
Re: Cloned titan extruder review/opinion...
April 17, 2017 05:08AM
I think my problem with fixed tension is that I spend alot of time fine tuning these things, do I trust someone else to have done that research for me? I think the fact that we all build these machines means no....

And then there are flexibles which spit in the face of anything you might have configured anyway!
Re: Cloned titan extruder review/opinion...
April 17, 2017 12:41PM
Whilst I sometimes adjust the idler tension its not often. If there was some sort of genuine self adjusting tensioner then I'd be all for it. Its one less thing to have to adjust, that doesn't mean there are no more things to tinker with.

I'm not sure that's possible although the bondtech extruders probably come closer with the dual-hobbed gear design meaning more grip and thus less tension needed... Might mean that the idler tension works well over a wider window and not need adjusting as much.
