Just testing some flexible filaments with the E3D-Titan and I am a bit disappointed... Thought that it would be capable of flexible material like advertised, but it looks like it isn't. Out of 15 rather short prints, I had 14 times filament knots at the pulley and after each fail, I adjusted things, I even completely disassembled the Titan and put it back together... Looks like that the filament guide isn't reaching close enough to the pulley, there is a 0,8mm big gap and even more in the middle of the pulley where the teeth are deeper. Is this like it is supposed to be? What's your experience with the Titan and flexibles?

Tested Filament: Polyflex and Filaflex at 30mm/s

I would go with 2.85mm filament with this extruder or be prepared to go down to 20mm/s with 1.75mm

So seeing as those who have these swear its the bees knees and theres nothing better. I figured I better give it a try. See how i like burning down my house or vibrating my tables with 8 bit move calculations. Should also give me the chance to frustrate myself with Marlin for a few hours right? Going to love re-uploading firmware instead of configuration via textfile... Those who swear by this and Marlin tell me its the best way to spend a Friday. Why, well, apparently that $5.80 it cost me here: https://bnc.lt/4Sug/md5FPboXFt?p=HO1614632392201406RX is such a saving compares to Smoothieboards I love, I may actually be able to cover about 10% of the 'cost of my time'

(; Oh, and maybe, if after all that I still have some sanity left, maybe I can start coding up the Marlin support for #LaserWeb3 if I can get this working as a test bed ;) - note statement surrounded by #sarcasmsmileys

+Mark Rehorst that's a reference/demo board to show off the drivers and processor... They're not trying to actually sell control boards. And as far as reference boards go, it's pretty darn good. Higher spec than most of what's on the market. Just needs some open-source love to up-rev the design and a commited dev to put better firmware on it.

So someone had mentioned the idea of easier swappable hotends. I spent a little bit of time thinking about a completely 3d printable hotend mount and this is what I came up with. This is just the mechanism that would hold the hotend to the extruder. The biggest problem with this design though is keeping the tolerances tight enough so there is no play. Therefore I am considering this design a failure. Magnets are definitely IMO the best solution for this problem. But I'm curious, does anyone else have a better idea?

Can you recommend a "thing" or ready to buy thing / link for showing of parts on a turning device? Like the one for 3d-scanning but without the scanning ;) It's for shopwindow use...

The axis don't have any units, so the graph is completely meaningless for comparison to any other printer. Yes, carthesian bots have the same Z resolution everywhere in the XY plane and delta robots suffer from reduced resolution in different places. What are you trying to say?

I think the final form of this statue is matel frame and fiberglass pieces plus some printed parts.they bought 20 machines printing 7X24.they told me that they printed over 1000KG PLA last year.

So my first silicone heater failed after being moved back and forth from printer to printer - at one point, it simply stopped effectively heating, and from testing around it felt like a broken wire. So i cut it open to get a better look inside!
The thermistor is crimped and insulated in PTFE tube, i suppose that was round at some point. And as expected, it's simply sitting on top of the heater part. Now, the heater wiring is where it gets interesting: There are sheet metal brackets embedded in the silicone, supposedly for strain relief, which have the supply wire soldered on on one side and the heater wire simply wrapped around the other. I guess this is where this bed failed, since its much too easy for the coiled heater wire to lose its tension over time and then score and burn the few contact points that are left. I think this should really be crimped in some way and not just wrapped, but there might be some technical factor inhibiting that.
For good measure, i then sliced apart the rest of the bed to see more of the heater wire, and it all seems to be solidly embedded in the glass-fiber reinforced silicone.

This one failed after about two year of intensive use, what are your experiences with these heaters?

I like the idea of running nichrome wire on a Kapton backer. Use a pre-cut one if there is one that fits your need. Routing your own would take some planning to be sure it's within a target power range. The nice thing about the silicone ones is they can make a custom size, shape and power.

To anyone interested, I am now an official reseller of the BLTouch in Canada. Until I get my own web store set up, you can purchase it at my eBay store at the following link:

BLTouch Review
April 13, 2016

I am a relative newcomer to the 3D printing arena. Although I have been observing the development of the technology for a number of years, the idea of taking the leap from electronics in computers to mechanics in a printer daunted me. But I finally decided to take the leap when I saw a low cost, decent quality printer appear on Kickstarter in August of 2014. Unfortunately, that project was a major flop. But fortunately I was able to learn a great deal from it. Although the design of the printer was questionable, the concept upon which it was designed on was salvageable. After a number of months of tinkering, I was happily printing with decent quality.

One of the things that this printer was not originally designed for was probing and auto-levelling. Being a stubborn and diehard cheapskate, I tried everything I could minimally do to work without the probe. Alas, I finally had to admit defeat and started looking at the options. The most popular probe in the 3D printing arena appears to be the inductive sensor. I wasn’t crazy about this as it required having a metal bed or in the bed in order to operate. Another option was to use a servo with a switch attached to it. I still wasn’t crazy about this either as it seemed more complicated to set up. Around this time a brilliant new type of sensor was introduced on Indiegogo called the BLTouch, a device that combines a servo with a switch in a less than 11 grams or 0.39oz package. As soon as I saw how this device worked I knew it was exactly what I was looking for and so I happily supported the project.

The project was a success and soon after the campaign ended I was working on setting up my first version of the BLTouch, the yellow one. Not long after receiving it however, ANTCLABS, the company behind the BLTouch, advised the backers to discard it as a new improved version was going to be sent to replace, free of charge. The new version addressed power requirements and added a feature to reset the BLTouch when in error condition by a GCODE rather than having to power cycle it and was now white to differentiate it from the original yellow one. Since this second version was released a "C" version is now coming which adds additional features that I will cover at a later date.

The one thing that made adoption a little more difficult at first was limited documentation on how to make it work. Although some connection details were available, programming direction wasn't certain at first for some firmwares. So, a number of backers were left scratching their heads, unsure how to configure their printers. Fortunately, some resourceful backers were able to discover the related settings on their own and shared their findings with the community. Since then, ANTCLABS has been actively adding support material to their forums and documentation and actively helping the community to get their devices working.

The makers of the BLTouch, Charles Lee and his team, have been very professional and supportive of their backers. I’d have to say that this was the most successful and professionally handled crowdfunding project I have personally supported to date.

I was recently asked about my standard deviation results from a M48 repeatability test. The claims made by ANTCLABS is 0.001 deviation. I didn’t get that small, but pretty close at an average of 0.005. I presume results may vary depending on the configuration of your printer. But I still consider that to be pretty good.

I am very happy with the BLTouch and the company that supports it. I would highly recommend it for anyone considering a reliable and accurate probe for their printer.

I ship with tracking. Shipping is then based on Canada Post rates and is calculated by eBay. That does sound a little high though. If the shipping gets overcharged than the actual shipping, I will refund the difference.

I'm sharing a selection of free downloadable basemeshes for anyone who'd like to have some fun with them. They usually have nice clean topology and are highly customizable. They are also watertight and should 3d print. I'm sharing them under the Creative Commons Attribution 4.0 license so feel free to use them for personal work or commercial work, it's all good.

Grab them here, and I'll keep adding more: http://shinbonecreative.com/free-stuff/

+Nathan Walkner you can't stop direct sales via AliExpress or whatever, but when there are established US distributors and resalers involved (say FlashForge, Wanhao, Afinia, etc) I think you can go after the importers. (You can with patents anyway -- I'm less sure about copyrights.)
