thanks for the feedback, just wanted to see if the info i was give was true or not. I hadn't see anyone talk about it so it leaves one wondering?

Two questions for the community here. First I've had a wierd problem with my heated bed where sometimes it will work and sometimes it won't. On closer examination I found that one of the power wires going into the control board was screaming hot, had oxidized and melted both the power connector and the insulation on the wire. So I'm guessing my bed was turning on and off because the melted connection and oxidized wire were only making spotty and intermittent contact. Now on to the questions. . .
1) I discovered that I had cleverly hooked up the power cables for the heated bed backwards to the board, I don't know enough about the wiring of the bed to answer this but is it possible that having it hooked up backwards was causing it to pull too many amps and thus overload the tolerance of the powersupply connector and or wire (thus causing them to melt)?
2) I'd like to replace the little green power supply connector as with it being partially melted it doesn't really hold the wires very well. But I can't seem to figure out what the darn thing is called when I search for one to buy. Any advice would be much appreciated. I've attached a picture of the part to clarify.
Thanks in advance

Wow that is pretty nice. I've been trying to get a good 3d benchy out of natural ABS, but so far they're pretty rough. I'm still tweaking my parameters. Went to a printer meet-up not long ago and watched someone's Lulzbot Mini print out a beautiful one with almost no adjustment. OTOH, that machine costs about 4X the Folgertech kit and you don't get the entertainment of making it work.
Did you manage to get the name on the back of the hull visible?

What printing speed did you use? I recently found that knob to tweak.

Hello,
I bought the Folger Tech 2020 i3 a few weeks ago.
I got it running and made a few very good prints, but the thermistor had been acting faulty from the beginning, sending MAX and MIN temp errors once in a while.
I was able to fix this each time by wiggling the wire around. Then in the middle of a print, it suddenly started saying the temp was only 130, because of this it overheated and ruined my extruder. I figured this was a problem with my thermistor, and contacted Folger Tech for replacement parts, which they sent right away. The parts came, and I installed them, but it didn't fix the problem. I tried unplugging the thermistor wires, and restarting the printer, but nothing helps.
Also, I don't know if this is relevant, but it displays the temp 125 for a half of a second when I start the printer up, then changes to 130.
Thanks,
Sam

As far as I know, wiring the bed backwards does not draw more current. The green things are called terminal blocks. Searching "four pin terminal blocks" should work. There have been quite a few people that have had the same problem with the terminal blocks. Some people have said that these ramps boards do not come with terminal blocks that have the proper contacts to conduct the amount of current that the hotend or bed can draw without getting hot.

Yep, the stock blade connectors seem to corrode vary easily leading to catastrophic failure; heat-resistance ramp-up. I wonder if Noalox would be helpful. I should take an eraser to the connectors and add some dielectric grease. Your direct solder should do it, you could put an inline resister on there too.
I have most of the parts to get the heat bed power off the ramps board I just need a 24V supply...someday.

finally printed some things!
Did the 40x10 print cube, measured thh walls, set the extrusion multiplier to .94, printed again, it came out right, so then I printed a Benchy. Wasn't thinking ahead, and was still using the sample filament sent by Folgertech, and started the print. So, I just stuck some Hatchbox black in the hole when the sample ran out.
Using Pronterface/Slic3r, 220° hot end, 65° bed, 0.3mm layer height, nothing on the glass... It turned out ok; I wouldn't call it a failure, but it definitely shows that there are some adjustments needed. The fun part is learning what they are...
The biggest thing is this wierd gap on the lower sides, (I think maybe something mechanical), and the front end slight deformation might be something to do with heat or extrusion of the different filament than I started with (the sample measured out at an average 1.77mm, while the hatchbox measured 1.74).
after looking at the photos on the PC instead of my phone, the front end of that thing looks like it got attacked by a flying spaghetti monster, yikes!!
good news, the straight 8mm y-axis rod came in from Folgertech, and I ordered a couple from VXB as well as some bearings, so I can make a filament spool holder right away.
Critique away, hints/tricks/tips are welcome. It's been a fun road building this so far, I can only see it getting more fun, as long as my wife keeps enjoying watching it print stuff out..

Did you do an Extrusion Calibration Test before doing the cube to set your multiplier? Did you run your Benchy at the same speed as you ran the test cube? 220 is awfully high for PLA. Try it again at 190 and keep the speed down to around 40.

My extrusion stepper calibration was similar to Triffid Hunter's, but instead of measuring from the body up, I measured the actual filament extruded from the tube:
I took off the nozzle, made sure the filament was flush, sent an M302 to allow cold extrudes, fed 100mm with Pronterface, marked it with a sharpie, removed and measured from the end of the filament to the mark, changed the E-step/mm in configuration.h (#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,4000,90} ) to 95.8, re-ran the test, changed the value to 94.7.
Then I printed the first cube, got an average of (.50/(.54+.54+.52)/3)= .50/.53333333333333=.9375 ), so changed the extrusion multiplier to .94. printed the second one, and got .50 for average, so i tried the Benchy. I knew the temp was a little high, but at this point I was getting over-eager, so just went with it.
I skipped over the tempereature-per-filament test, and jumped right to printing something. Mostly because of gung-ho, but partly because I'll have to redo calibrations when I put in the 'straight' y-axis rods, and move the printer to where it will normally sit, and this will give me a head start on fine tuning it when I finally get there.

Almost done with my Folger Tech 2020 i3. I also ordered the display controller with the printer. Where can I find information on wiring and mounting the display? Sorry for the double post I think I'm in the right place now.

Has anyone used the 'change filament' option via the LCD? (Needs to be enabled in Marlin first)
It moves the print head out of the way correctly and retracts the filament, but after I've swapped filaments and clicked the LCD button to continue it does another retract after moving back to the correct position.
This results in several empty layers printing before the new filament reaches the nozzle again.
I've had a look in configuration_adv.h (FILAMENTCHANGEENABLE) but there's nothing in there to change for after the button is pressed....
#if ENABLED(DELTA)
// Move XYZ to starting position, then E
calculate_delta(lastpos);
plan_buffer_line(delta[X_AXIS], delta[Y_AXIS], delta[Z_AXIS], destination[E_AXIS], fr60, active_extruder);
plan_buffer_line(delta[X_AXIS], delta[Y_AXIS], delta[Z_AXIS], lastpos[E_AXIS], fr60, active_extruder);
#else
// Move XY to starting position, then Z, then E
destination[X_AXIS] = lastpos[X_AXIS];
destination[Y_AXIS] = lastpos[Y_AXIS];
line_to_destination();
destination[Z_AXIS] = lastpos[Z_AXIS];
line_to_destination();
// Don't try to put E back - this can only cause problems, and isn't necessary
// destination[E_AXIS] = lastpos[E_AXIS]; // Line 5434
// line_to_destination(); // Line 5435
#endif
