Hi cold front and jjbunn, after repeat test here is what I found, I follow previous post, I connected the power to the hot bed, on P1, 12V positive goes to pin 1, negative goes to p2 and pin3. this is when the shut down happens. If I connect the nagetive to either pin2 or pin3, it doesn't shut down but only half of the bed is heated. Also another strange thing is when the negative connected to pin2, a LED comes on, but when connects to pin3, no LED at all.
Is there something in the Configuration.h needs to be tweak? Also my power source is an ATX PSU, it's rated 12V 20A output, that should be sufficient to power the entire hot bed, am I correct?
Oh I forgot to mention, I did get the positive on pin1, nagetive on pin2 and pin 3 to work like once or twice.

My choice : Igus RJMP-01-08 . You can also find good quality regular linear bearings : [www.ebay.com]Quote

Anyone use any LM8uu linear bearing alternatives? The ones included lose balls like crazy and are the crunchiest bearings I've ever seen. I'm thinking of getting some 8mm bronze bushings.

Hi jjbunn,
I checked the bed, the resistance between pin 1 and 2, as well as pin 1 and 3 are very low but consistence, so there is nothing wrong with the bed.
This morning I got up the first thing I did was to re-wire the negative to pin 2 and 3, reloaded the firmware. Magically, IT WAORKS!!!!
May but the printer needs a good night of sleep too.
Now perhaps the last question, I tried a test print of a small object, the filament came out, but it came of as a brup of modem art.(Pic morden art.jpg)
Why doesn't it stick to the glass?

Endstop issue.
Background: Green wire is facing outward on ramps. Physical locations: X=left stop, Y=back stop, Z=bottom stop. Stock Folger tech firmware/configuration.h besides whats shown below.
I can manually go one direction via pronterface but cannot go the other direction. This is with:
const bool X_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
const bool Y_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
const bool Z_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
I can manually go one direction via pronterface when end stop is not depressed. When end stop is pressed, I can go both directions!
const bool X_ENDSTOPS_INVERTING = false; // set to true to invert the logic of the endstops.
const bool Y_ENDSTOPS_INVERTING = false; // set to true to invert the logic of the endstops.
const bool Z_ENDSTOPS_INVERTING = false; // set to true to invert the logic of the endstops.
how do I get these endstops to be actual end stops!?
I just want to print a cube
#define INVERT_X_DIR true // for Mendel set to false, for Orca set to true #define INVERT_Y_DIR false // for Mendel set to true, for Orca set to false #define INVERT_Z_DIR false // for Mendel set to false, for Orca set to true #define INVERT_E0_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false #define INVERT_E1_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false #define INVERT_E2_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false

Looks like you need to get closer to the build plate.
you should also use hairspray as an adhesive.
make sure you properly level your build plate, it will take a while to get the hang of it,
dont get discuraged... but you will have to make a bit of an effort... and once you sort it out,
it will take less and less time to do it before you print...
also, make sure you level the build plate while everything is hot... as it will make a difference.

Waltermixx, just wanted to give you a big THANKS! for starting this thread. Without it, I don't think I'd be printing with this printer and would probably just bought a pre made printer like the XYZ or something as my first printer. I'm glad I went down this road. I've learned so much.

Received my kit now to start
Two dumb questions.
Is there a master parts list or just the list on ebay? (Want to make sure I have all the parts)
What is the best instruction on how to assemble it.

I couldn't find a list of parts, other than what's listed on ebay. As for the instructions:

my kit had a check list of parts taped to the inside of the box lid flaps...
things were checked off the list as the boxes where filled with parts...
my kit was missing all printed plastic parts, (so I printed my own from the stl files Folger Tech provided)
while I waited for them to send me parts, which they did right away
I ended up using my parts because they were a very cool orange...
so dont throw that box away, look for that packing list...
plus the ebay listing includes a list of parts as well.
hope this helps?

Send an M119 to the printer to find the status of the end stops and/or use a multimeter across the pins.
The:
const bool X_ENDSTOPS_INVERTING = true; (or false) sets in the firmware whether the switch is NO ir NC (normally open or closed)
You also need to set:
#define X_HOME_DIR (and Y and Z) as MIN or MAX
X stop on left side is a MIN, Y at back is a MIN and Z is MIN
There are also MIN and MAX jumpers on the RAMPS where the wires from the switch plus into

Hey everyone, getting close with my folger kit and have a quick, possibly repeat, question. The thermistor for the heat bed, was there supposed to be one with the kit? Other than some 3m hardware it's the only thing I can find missing in my kit.

AAAAAAAAAAH! It's baaaaaaaack!
This is driving me crazy!
After working for like 15 minutes, the problem comes back.
I isolated the problem by connect the 12V negative to Pin2 alone, then pin3 alone, in both cases it works fine, so it confirmed that the bed is good. Correct?
The only two possible causes I can think of now is 1.) Is there something I need to tweak in the Configuration.h? 2.) I use an ATX PSU, the 12V output is rated 12V 20A, Is 20A not enough to power the bed?

Some suggestions:
Did you check the vrefs?
Maybe you should decrease the head temperatutre?
You can place a piece of cardboard over the bed as you heat it and when it reaches temperature you remove it! It will speed up the process by much! I can reach 100 degrees in 15 minutes from cold!

At present, I used some settings posted by another user quite some time ago (sorry, can't remember ID):
X: 0.33V
Y: 0.55V
Z: 0.35V
Extruder: 0.35V
This also begs the question, as there is no visible movement with the cold end, how can you perfect the extruder vref value having nothing to go on?
I have also wondered about what the correct vref should be placed at... If I look at the datasheet for the motors that folger supplies (http://cdn.shopify.com/s/files/1/0586/8617/products/1_99a367d7-465e-4190-a765-192b500987e2_grande.jpeg?v=1414115409). It says the small motors for this example are 12v and 0.4a, and if we take the vref formula (VREF=I×8×0.05=0.4×I) shouldn't it be VREF = 0.04A x 0.7 x 0.4 = 0.16V?? Also anything under .40v is safe correct?

Walter, first of all thank you and everyone else who's contributed to this thread, it has been tremendously helpful! I have a question on the dissassembled extruder pics above. Is that a couple of washers in it, or a bearing (maybe 623zz)? I ask because I don't have anything in mine and am not getting reliable fillament feeds - not surprising since it looks like that piece is necesary. I do have two washers that fit, but they have a lot of play on the peg, though in a quick test fit, seem like they might do the job. I don't have any extra bearings, I've used the two included bearings for the x and y idlers.
Thanks again to everyone!
Mine was a one piece grooved bearing. I dont recall if it was marked...
