Any updates on this since your June 27th blog post? I'm getting close to wanting to try this on my machine, and was curious if you were any closer to providing a write-up before I go the road alone.by maddox - General
What trimmer line in particular are you using that you prefer?by maddox - General
Cool post. Did it just stain the piece, or does it also affect the dimensions at all?by maddox - General
Yeah, silicone hoses fit the bill for sure. Silicone 'vacuum hoses' for cars are easily accessible, if anyone is having trouble finding them.by maddox - General
Yeah, I think water cooled is the way to go with a heated chamber. Also, regarding the snorkel, some of the Stratasys Dimension printers integrated this into cooling the hotend.by maddox - General

That is actually a question I had for you Werner, did you ever test/calculate if the angles in the metal are absolutely necessary to get full travel? If not, that would make this much more DIY friendly for those without easy access to a brake.by maddox - General
Stratasys uses a conduit to pipe in cool outside air into the heated case to cool the carriage as well, though theirs is a larger diameter tubing and doesn't have a return setup. I was considering doing similar and actually running the Bowden tubing and wires inside of a larger air tubing. Glad to a successful utilization.by maddox - General
While I think the cause is noble, unless one is a patent attorney themselves (or wealthy enough to hire a patent attorney for the interest of others), and willing to donate their time/knowledge, it seems that patent law and litigation will only serve to protect self-interest.

It sounds like I may have misinterpreted it (and I hope I have), but if I did, then I'm not sure how to understand the 1 year rule. Let me throw out a couple hypotheticals to clear it up for me: Situation A: Bob invents something Jan 1 2015 and publishes it in a blog, but never applies for a patent. Jacob files for a patent for something substantially similar in 2017. Is the patent awarded toby maddox - General
With the newly changed 'first to file' instead of the legacy 'first to invent' in the US, I think this is especially worrysome for individuals in the reprap community who previously may not have worried about their stuff being patented because they were verifiably the 'first to invent' and could easily have claimed prior art under the old system. Now, it's only protected for a year from first puby maddox - General

That Stratasys Ultem is a Sabic resin, and I might try to get my hands on some to extrude into filament myself. I heard some pretty crazy numbers about the machine when they print the Ultem though, something like extruding at 300 C and they have the heated chamber above 100 C IIRC.by maddox - General
I look forward for the feedback from the people who formerly had clogging issues. I hope the new batches cure any previous issues.

Has glue stick on glass been thoroughly vetted yet? I've heard of a couple of success stories over the past little bit, and if that works on heated glass like it did for the few people I saw, sounds like it might be perfect. Allows for a heated platform to help with warpage, sticks well, then comes off with water. Anybody had experience with it?by maddox - General
Thanks for the input Mattcad.by maddox - General

Do you have any drawings of this hotend? Are there different size nozzles available, is 0.4mm the only size?by maddox - For Sale
Kinda bummed that these promising new metal nozzles (the E3D and this) are being plagued with these issues. I guess it's all a necessary step in the evolution of all-metal hotends though, and will hopefully be worked out in time. If these issues don't get worked out soon enough, I may be forced to go with the reprappro hot ends.by maddox - General
Great blog post, and I have actually been looking to utilize load cells in a different area of the 3d printer. Anyways, have you gained any insight from this about specific qualities that a 'PLA specific' extruder might have (geometry, etc)?by maddox - General

Awesome video Werner. I asked this in the youtube comments, but it's probably more appropriate to have the discussion here. Did you by chance measure the total length of the vent hood? If so, how was the accuracy of the longest dimension? How would you feel about the accuracy of someone scaling your design up even larger, say 1.33x your machine's size? What's the diameter/longest dimension ofby maddox - General
