Re: hotend plugs
Its been covered in other threads, but the proper Solidoodle ones are from TE Connectivity and can be had from Digikey or RS Components. http://www.digikey.com.au/product-searc … mp;stock=1 . The different colours are used to denote the differnt wire gauges of the connector - Red is 22AWG, Blue is 26AWG etc.

Re: hotend plugs
I detest those OEM connectors. so weak and the wires kept falling out of mine. So when I upgraded to my jhead and new extruder assembly I used a 4pin ATX extender to do this. Much better connector. positive snap, but easy to remove. And rated for upto 75 watts, so not a problem for power ussage.

where is your thermistor mounted? I can't see it.

Re: hotend plugs
Looks nice! Can anyone point me to a page or explain what the difference is between the various types of extruders? I keep seeing mentions of J-Head, Bowden, etc and don't have a clue what the difference is.

Re: hotend plugs
Your post identfies different brands of Hot End (Extruder) available for 3D printers. Each brand has a different design and requires some custom mods to make them work with the Solidoodle printer. Some of the more creative people on this forum have modified their printers to accept non-stock hot ends. Each design has features that may improve prints, maintenance, and/or repairs. Obviously, the stock hot end directly from Solidoodle is the simplest replacement since it is the original. If you want/need to upgrade your hot end, search this forum for that particular brand to identify what you will need to do to convert. the J-Head seems relatively popular. Here is a link: https://www.hotends.com/index.php?route … duct_id=88
A Bowden extruder removes the motor from the moving assembly to reduce weight. A PFTE tube is run from the back of the printer to the hot end and the filament is pushed through it. The motor drives the filament from the back of the machine to the hot end instead of pulling it directly at the hot end. Someone on this forum has used a Bowden system and made a dual extruder Solidoodle. A dual extruder uses two separate rolls of filament and allows the user to print with two separate colors or run two separate types of material (ABS and PLA for example). PLA is sometimes used as support material for ABS printing when printing complex prints. PLA is easily removed from ABS after the print is created. This is not a Solidoodle, but this link shows a Bowden Extruder setup http://www.thingiverse.com/thing:90335
Most of the custom hot ends require different mount systems and can sometimes reduce the height the printer can print. If the custom Hot End is longer than stock, the 150mm (SD2) 200mm (SD3) height may be comprimised. You will see some new extruder mounts identified as MK1-MK4 that can be used with the original or custom hot ends. Whether you use a stock hot end or custom one, they all function in a similar manner. Each one has some form of heater and some form of thermister (Thermometer) to control the temprature. Some of these modifications require some tweaking in the software as well.

Re: hotend plugs
Oh ok, thanks for the clarification. I was under the impression J-Head had something to do with the design, which I suppose it is in a sense but I was looking for some curve characteristic that would explain the 'J'.

It is hidden in that picture. but the thermister is running up one leg of the resistor wire, so it cant fall out.
