3D Printer extruder PEEK insulator meltdown

[felix-extruderv4-peek-meltdown] chrono : Uhhhh, H0u5t0n, I have some good and some bad news H0u5t0n : Bad news chrono : I think we have a problem with F3l1ks H0u5t0n : Could you be a bit more specific? chrono : Well, seems as if the beige plastic element of extruder 0 melted H0u5t0n : You mean the beige PEEK insulator between the hot- and cold-end? chrono : Affirmative H0u5t0n : How did that happen? chrono : I was prepping him for a new job, manually set the target temp of …

3D Printer Hacking - Carbon as a printing bed surface

This is going to be very experimental and sorry for the short notice :) Since we now have a relatively efficient video stream relaying capability thanks to mjpeg-relay and a highly anticipated set of carbon sheets arrived today, it is time to remove the Kapton-Tape from the the 3D printer and replace it with a 0.5 mm carbon sheet. So, if you're interested, put on some music you like and watch the process live on picoPrint FrameCam Live-Feed.

Cable Management?

At long last the Felix 3.0B upgrade parts have finally arrived last week and the picoPrint 3D Printer underwent a complete overhaul. On Friday night the printer was completely disassembled, except for the bare frame. All printed plastic parts (V2.0) were packed away (as a backup for now) and all screws, nuts and other metallic parts took a bath in WD-40 for 24 hours and were cleaned, re-sorted and stored in the original container. Having only sunday left, the assembly of the 3.0B went up to th…

Fixes for chrony & RTC on Odroid C1 Linux 3.10.67 (ARMv7)

For a long time, all machines in Apollo-NG's infrastructure use chrony as a replacement for the usual ntpd package. chrony can be compared to ntpd like nginx can be compared to Apache, newer, much more lightweight approach and some additional very nice features. While nginx has replaced most of the Apache installations these days, chrony still isn't adopted as a good alternative by most people yet.

Monday Night Hacking

Tonight's work will be another live-stream, hacking on F3l1ks. After the 3D Printer extruder PEEK insulator meltdown, it seemed prudent to verify that the temperatures, shown and logged by octoprint are actually the temperatures of the bed or the hot-end.

picoPrint 3D Printer

Every Hackerspace or FabLab needs manufacturing capabilities in order to dramatically increase the edge of research and development possibilities. Where ever we go or whatever technical problem we might encounter, we can just build the parts we or others need to solve that problem. So, in the end of 2013, we had another look at the 3D printer market and a lot seemed to have happened since the RepMan. Almost all major tinkerer suppliers had some form of 3D printer to offer ranging between 600-900…

Sweet: The lab got a Mitutoyo 2046 Dial-Gauge

In order to reliably calibrate any kind of mechanical system, a dial-gauge really is a necessary tool. Today our Mitutoyo 2046S arrived and will be tasked directly to calibrate the bed of our 3D printer. Mitutoyo seems to have a similar reputation level for measurement tools like Makita has for battery powered power tools: A very high price/performance ratio. The lab already carries a couple of other Mitutoyo tools, a large set of Makita tools and both have already proven themselves in terms …
