After researching this answer to Why don’t 3D printer heads use ceramic inner walls? I found an interesting little video for an hotend upgrade – which, despite the name, uses PTFE lining…
Following on from Double the volts… double the fun! here is a nice little tip that I came across to avoid your 3D printer going up in flames…
Replace both polyfuses (PTC) (F1 and F2) in a RAMPS 1.4 board with car blade fuses 5A and 10 or 15 A respectively. The polyfuses, F1 (MF-R1100) is rated to 11 A 16 V, F2 (MF-R500) is rated to 5A 30 V
It should be noted that in subsequent versions of the RAMPS boards (1.5 and thereafter), the fuses are SMD (and may also require replacing).
For a long while I have wanted a Taurino Power 24 volt controller, and although they seem hard to find now, there is the Eruduino, which seems to be a reasonable clone…
Using 24 volts over 12 volts means, basically, less (half) current, thinner wires (or less likely to burn out the existing wires), less stress on connectors (where most fires start).
I just have to share this inspirational video about Prusa and how they got to be where they are today. It was pointed out to me by a friend in the chat room of 3D Printing site on Stack Exchange.
I’d just love to go there to visit and take the tour.
They have Open Wednesdays (Otevřená středa).
There are an awful lot of cheap MK8 extruders, and their derivatives (close and not so close), out there – with different number of parts, different bolts (lengths and thicknesses), screws, washers, varying arm designs (enclosed or non-enclosed bearings), etc.. However, not many assembly instructions. So I’ll ramasser a few different assembly pictures here.
This post was inspired by How to build the extruder motor holder for the Kossel Mini
As stated by Scott Lahteine [states midway through][7] this video, How it’s Made: The Marlin Firmware!, your wires must not be tinned, in order to avoid thermal issues, fires, etc.,…
…were from this vendor: ukings
Following on from Something from nothing, progress was sporadic/slow. After 5 months of trawling second hand markets in BKK, I ended up with 5 drives, two of which, although not being the same brand, look suspiciously identical.
I need a power supply for a 3D printer, my Kossel XL. I figured that a cheap LED supply would suffice, so long as I over rate it, and have a wide margin for safety, i.e. 30+ A.
So, how much is a SMPS in Bangkok? Cheaper than eBay or Amazon? Let’s find out…
