Solved it! Sometimes it is worthwhile to go back and remeasure what you thought you already measured. When I was watching the gear drive struggling to turn, I thought I saw a problem with the motor struggling to overcome the torque required to push the filiment through the nozzle. Not the case! I went back and stuck a piece of tape to the motor shaft, and then saw the shaft was turning just fine, while the drive gear wasn't turning as fast. You guessed it... the set screws attaching the drive gear to the motor had come a little loose.
After tightening the set screws, I'm now back in business!
One other side effect... I ordered an E3D Lite6 hotend, and a 5.5 kg/cm Kysan stepper motor, just in case the hotend or motor turned out to be the culprit. Looks like I'll be getting an upgraded hotend and motor out of this!

Awesome - good work! I have an E3D Lite6 as well. I slightly regret not getting the all-metal E3D as I get a bit nervous when the temperature is around 240-250, but you can buy just the parts for an upgrade. I have a few different versions of a mount for it, see [www.thingiverse.com]. It's a tight fit but you can do it.

I just printed your mount out in ABS as my first test print post-fix, thanks for putting that together! I plan to use it once the the E3D Lite6 comes in. Looks like your MK9 extruder is the same as mine, so hopefully it is a good fit. A few questions... It looks like your mount attaches directly to the E3D heat sink, which would cause me to worry a little about the ABS getting soft and distorting. Do the temperatures stay relatively cool at the interface? Also, I see you have a fan duct that cools the heat sink and the extruded filament. Is this fan on all the time?

Hey all,
Got my printer all set-up over the weekend, its been great fun and still getting the calibration right.
But I have an annoying rattle(?) from the Y axis bed. It only really does it on long and fast movements - see this video: [www.youtube.com]
I thought it was from the side with only a single bearing as it seemed to mainly come from that side. I also re adjusted the smooth rods. I also have put 3 in 1 oil into all of the bearings as has been recommended.
Any ideas would be a great help.
Cheers

I am very familiar with that rattle, and have never managed to make it go away! I've tried replacing and lubricating the bearing and realigning the chrome rods, and both more and less tension in the Y belt. Some days it goes away altogether, the next day it is back. I think what happens is that if there is any vibration, the aluminium plate acts like a sounding board. I think I read of someone trying putting a soft pad (like a soft plastic) between the Y mounts and the bed, but I've not tried this. I've just got to living with it.

This occurred to me as well! It looks like the only difference is the heat sink ($20) and heat break ($18), or $38 total. Since the Lite6 is $35 and the all-metal v6 is $75, with a price difference of $40, it appears $2 better to purchase the Lite6 and the upgrade parts! Unless I'm forgetting something.Quote

If anyone is interested in a super-easy way to decrease rolling friction for the spool and thereby ease filament tension issues, please check out this simple addition to the printer at http://www.thingiverse.com/thing:1119390. Print two of these, use the extra bearings that you should have maybe got with the kit and you'll be good to go in no time. I was finding before this change that I had some filament slipping on parts as the x axis was moving away from the spool quickly, which caused some gapping.

Switching to having 4 bearings on the Y axis got rid of that for me.

I'm happier than a pig in poop! I just finished three of these babies! It took a loooooooooong time but well worth it! They are beautiful. I also added the Z axis extension. I did note that the extensions' holes are too small for the boss on the bottom of the Z motors so I've changed the .stl file and will be printing new ones.
Oh, 190 C on first layer and 185 on the rest. 70 C on the bed with just hair spray on the tempered borosilicate glass from Amazon. Sticks like heck!

First: Beautiful work!!!
Second: Not sure if anyone has mentioned this, but I think you have your Z extensions upside down, the end with the rounded inner portion is for a 608 bearing the open end goes towards the top (connects to the motor). Or at least that's how the ones I used worked!?!?

My first forray into 3d printers, but I'm technical, i'm familiar with arduino stuff (i said) and it'll be fun (i said), and the product has been out for months so the manual should be pretty solid by now (i said)... and being somewhat naive, I asked around and decided to go with the FolgerTech 2020 (2 reasons: 1):recommended by a coworker that does 3d printing stuff, 2: Folgertech is based in NH, only an hour drive from my house, support local economy+1).
Off and on working on this for a few weeks and I'm almost done putting this kit together; the motors work (home and endstop properly), the device doesnt burst into flame or short out.. and now i'm debugging what could be a hardware problem with my RAMPS board..
It looks like the thermistor inputs from the hotend and the hotbed are Not being read in by the Arduino (looks like either a serious Marlin issue or a problem with the RAMPS board).
Per the configuration manual, no values were changes in the Marlin settings from the GoogleDrive location.
When connected with Repetier-Host (and on the Serial monitor in Arduino software) the system is returning the following error:
start echo:Marlin 1.0.0 echo: Last Updated: Nov 8 2015 5-20-15 14:47:22 | Author: (FOLGER TECH, 8 i3 Prusa Config) Compiled: Nov 8 2015 echo: Free Memory: 5512 PlannerBufferBytes: 1232 Error:0 : Extruder switched off. MINTEMP triggered ! Error: Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)
Troubleshooting steps so far:
1) I've validated that the thermistors (100k EPOS NTC) in both the hotend and the bed are both returning valid values (multimeter) properly with varying resistance on temp change (temp up = lower resistance, 120k->110K with a finger on the sensor).
2) I've validated the Marlin arduino code is pointing at the proper pins (pins.h) on the RAMPS1.4 board for T0/Extruder (a13) and T1/Hotbed (a14). And that the MinTemp for both is 5C (configuration.h).
3) I've applied a 100k resistor to the sensor pins so the software (if it were getting any signal from the pins at all) would get the equiv resistance of 25C on the 3 Thermistor sensor pinsets (T0, T1, T2); still throwing the MinTemp error after reset. Same (neg) result when I shorted the Thermistor pins with jumpers.
* The RAMPS board seems to be working for everything else though; X,Y,Z motors all move and Home properly (albeit the bed and hotend arent getting power, but that's an expected software safety with the thermistor issue).
* From what I've read online, this could mean the Ramps board or the Arduino is broken. So, I flashed the Marlin code on my own MEGA2560 (mine is branded for SunFounder and it looks like your Arduino is mfg'd by the same company as the PCB logo/backing is exactly the same - yours without the brand markings) and got the same problem
All this leads me to believe this is either some convoluted software/configuration issue or a bad RAMPS1.4 board.
Any suggestions for what to try next?

I'm thinking the same. Did you just drill your bed or buy a new one?
Maybe something like [www.ebay.co.uk] or [www.ebay.co.uk]

HI. I just finished assembling my printer 2 days ago and have had fun printing a few things.
I did calibrate the axis, but have done no other tuning. All of the settings are the default set in the config guide and presets from Folger Tech. (The guide is here [drive.google.com])
A few questions:
It looks like in it's current configuration I only have ~150 mm available on the Z axis. Is that normal? I see there are adapters available to move the motors above the brackets to give you more room. I'll probably print them soon.
One of the first prints I did was a 10X10X10 mm cube. I kept all the default settings in slic3r. It printed well, but the top of the cube sagged in. I tried increasing the infill from 10% to 20% and lowering the temperature from 219 to 205 (I'm using hatchbox brand pla filament), but it still sagged on a later print. How do I fix that?
I tried printing a little figuring that I knew would need support so I ticked the box to add pillars and kept all the default settings. It made a LOT more support pillars than I thought would be neccicary. I printed it anyway but I ended up ripping off the figure's head and arms trying to get the pillars off it. Any suggestions there?
Whenever the hot end is hot, it seems to constantly leak a little bit of filament. Is that normal?
Maybe related, when moving from place to place during a print, it leave little hair fine strands of filament behind. Is that normal?
Thanks in advance for the help.

The issue with the Z axis only giving 150mm is indeed normal. Interestingly enough though is that I get less on my printer. It is also normal for the hotend to leak a bit. The hotends that FT gives I would say are on the lower end of the quality spectrum when it comes to hotends, but even higher quality hotends do still leak. Yes the small hairs that are left during travel moves are normal, but these can be reduced by increasing the retraction. I have disabled retraction with my printer because it seems to cause me more problems that it solves, but having retraction on is fine too. As far as the problem with the supports, I would suggest maybe not even bothering too much with slic3r (personal opinion). I have not actually used slic3r myself (I use cura) but from what I have heard, it seems that cura is better at everything from slicing to overall print quality. If you are just getting used to a using slic3r, I would suggest switching over to cura before getting to accustomed with slic3r (again personal opinion)

Is there a stl file for the folgertech prusa i3 2020 bearing holders for the y axis rods? I sorted stripped the screw holes of mine from running my printer head down onto the build plate and luckily the screws gave way and made a pop noise that alerted me that the the end stop didn't trigger (mightv got moved when messing with something earlier) and now I can still print but it vibrates from the bed not being securely fastened. I would've noticed sooner but I had my noise cancelling headphones on and the pop is what came through.
(If i have to I can probably do measurements and draw up my own to print but I figured I ask first for ones that are exact)
