Have you ever wanted to upgrade your hotend or extruder system only to find that new unit uses a K-Type Thermocouple or another Thermocouple; if you have ever tried to just plug that into your RAMPS 1.4 or other board you'll find out fast that it just won't work.
You need a break-out board to get the job done... well, the crack MakerGeeks research team found this little gem and started making it up so you can, "plug 'n play" your K-Type Thermocouple with your RAMPS board.
Very nice to have around and easy to use to, here's what you do to hook it up: For two-pin connector, "+""-" to thermal-coupler; For three-pin wire: "+""-" to power, "S" to main-board.
Then here is what you need to do in the Config file in Marlin (it's the same for Sprinter Firmware):
a. modify Configuration.h on firmware Marlin:
#define TEMP_SENSOR_0 -1
(the value is set to be -1)
b. modify pins.h on firmware Marlin:
Find configuration for Pins on Ramps1.4:
If the original value is
#define TEMP_0_PIN 2
We'd revise to
#define TEMP_0_PIN 3
(p.s We can not use the original pin for thermistor. The recommended is A3, as it is located next to 5V and GND, so quite easy for connection).
c. connect thermal-coupler to this board (need to check if polarity is correct), and connect signal to this breakout board.
d. connect signal wire to Aux-1 on Ramps, red wire to 5V, black wire to GND, green or blue wire to D57.

What Temperature to 3D Print your Filament at?
While each 3D Printer is different and you will need to play around with the temps to get the best print here are some starter temps for you; these are all temperature profiles that are verified and confirmed print temps on the MakerGeeks.com 3D Printers (9 different machines from pre-built D3 and D4 to our own DIY custom Reprap printers) with the actual filament we sell to you... so they will get you 99% of the way there!
This one is a multi-faceted answer but here are the basics:
Your print bed has to be level!! I mean, spend some time on this one... if it isn't level like a... well... like something that's really level - then your print won't stick and it won't come out looking right.
Next... CLEAN, CLEAN, then RE CLEAN, have a sandwich and a soda-pop and then CLEAN again... use acetone and a lint free towel to make sure your print surface is clean and free from oils and dirt.
If you are having a hard time printing on glass try using some Kapton tape as that will give you a little better stick
If you have a heated print surface... TURN IT ON!! Even when the filament used might not call for it, I always turn on my heat bed (who doesn't like a warm bed!!); even if it's just 40c it will really help. For PLA normally you'll want about 60c and for ABS you'll want 110c
For ABS 3D Printing room temperature really matters... you need to keep your entire build warm; so if you can't print out in a warm room try putting a box over the printer to keep that build area as warm as possible.
Try making "ABS Juice" - just add some scrap ABS filament to a bottle of acetone and let it dissolve and then use that to clean your print surface as normal; the dissolved ABS will give your printer extra STICK OR you can use "Aqua-Net Super Hold" hair spray (must be this brand to work right)... just clean your board as always and then lightly spray the Aqua-Net on the print board and print away (this method is my favorite as it seems to work best for me!)
KEEP trying!! You'll get it and once you do have it dialed in then you have it forever... each printer is different; make sure you make notes of what works and what doesn't for each filament you use and each printer you have. So, in the future when you want to print out that EPIC "Yogi Bear" figurine in MakerGeeks.com Blue you know what to set up your GCODE for.
What is the main differences between PLA and ABS 3D Printer Filament?
The main difference between PLA filament and ABS filament is that ABS is produced from fossil fuels and PLA is derived from biological resources, which makes PLA plastic biodegradable. Check out this 3D Printing Filament Impact Test -- PLA vs ABS vs PETG vs Sledgehammer (click here to watch the videos)!! When it comes to 3D printing the key differences between ABS and PLA are:
PLA is a rigid liquid and ABS is a crystallized liquid, meaning that when heated ABS transits slowly from a gel to liquid and PLA transits direct from solid to liquid.
ABS is more flexible and PLA is more solid, meaning when stressed PLA will snap sooner.
PLA is more glossy looking consumable than ABS (see photos when selecting your material).�
Wow, you have a 1kg spool of filament... SO What! How much actual filament is that??
Big question of the day is... how long is a spool of 3D Printing Filament!? Hummmmm, I think even Blinky the wise old MakerGeeks.com owl might have a hard time with that question but never fear... we have the answer!!
... and what does that mean to me and you!! Well, check this out... if you are printing with 3.00mm filament for a iPhone case you need about 2,700mm of filament; for a EPIC Starship Enterprize Model you'll need about 12,000mm of 3D Filament and for a full Kossel 3D Printer Kit we normally use about 50,000mm of filament. Another way to look at it according to MakerBot is that 1 spool of 3D Filament produces about 392 full sized chess pieces. Whoa... that's a lot of chess!!
