Check in case the gear on the extruder is slipping. Sometimes the grub screws can work loose.
Check whether the V-grooved bearing in the extruder is rotating freely. These are quite cheap bearings and can wear out.
Check whether the nozzle is blocked (partly in your case as some filament is getting through). This is a bit harder to see directly, but maybe you can drive some filament through by hand. If you have some fine stiff wire such as welding wire or a guitar string, you may be able to run it through, but be careful to avoid damaging the liner.

We need to address the X-endstop problems here, and probably recommend putting it on the left

The 156 pages of this thread make me order it as my first 3d Printer
It should arrive next week, hopping that custom fees - I'm in Canada - won't be too much (not idea how much that will be).
I'm not afraid to tinkle to make it works the right way.
Thanks to [folgertech.wikia.com] it looks like a good start.
There is also some nice stuff here: [www.reddit.com]
But I still have one quesiton:

Is there some details about the left mount of this endstop, I would prefer to mount everything the right way(then print parts to upgrade it).
I also starts to dig around OctoPi that looks gorgeous (and as the printer will be in the garage downstairs, its a must have to check the printing progress IMO).
I hope my kit will arrive with all the pieces and in good shape!

If you use the google docs build guide linked in the wiki (alongside the original guide or Cyberkni guide) that will tell you to mount the x endstop on the left hand side of the printer instead of the right hand side like in the FolgerTech guide (so it's a 'min' endstop (same as Y and Z) and not a 'max' endstop). You will also need to connect it to the RAMPS board one set of pins over from what the original guide says. This will make a lot more sense when you actually get to this stage during the build procedure. Also make sure to use therippa's Marlin firmware instead of the one FolgerTech provide. You'll also need to change a line in one of the Marlin files. If you go to therippa's github to download his Marlin version you will see the info at the top of the page.
Hope this helps

Hi all.
I read a few pages and did a few forum searches (would really help to search inside specific topics) but I can't find if this has been asked before. I just finished assembling the basic structure (next step would be soldering the heated bed) and I'm feeling a little unsure about the position of the SK8s specifically. The rods and aluminum bed are already in place, should I use that to eye their right position? The manual in more than one stance says "this will be adjusted later" and never really does, from what I saw ahead. I would really appreciate precise measurements of the pieces' positions. The only time there was one it was ill defined; "the vertical 2020s' back have to be 90 mm from the back of the printer." If I use the actual back of the printer it gets way too far when comparing to the pictures, so it means 90 of space between this 2020 and the back 2020.

Going through the instructions I notice some stuff:
......
Same thing with Aluminum heat bed plate [github.com], I think we can attach the LM8UU Bearings under the place and them just slide the all thing when we are attaching the rails [github.com]
Those are tiny things but I think this could make it easier and quicker.
What do you think about?

That's the way I did it too. I also changed the stepper bracket to the opposite side, compared to the build photos.Quote

Don't mess with the hex adjust. Just go into your Starting GCode in your slicer and put the following at the very beginning and it will reset any alarms and put the pin in the proper position.>>>
M280 P0 S160
G4 P5000 : wait for alarm reset to clear
M280 P0 S90 ;pin up
If you are using SLIC3R, you only have to do it once. For Cura, you have to put it in each version of the print setting that you created.

Thanks for the tip. I'm using Octoprint so I added the following to the "run after printer connected" script:
M280 P0 S160 ; Reset BLTouch sensor
G4 P1000 ; Wait for alarm reset to clear
M280 P0 S120 ; self test BL Touch
G4 P3000 ; Let self test run a few seconds
M280 P0 S160 ; Reset BLTouch sensor - stop self test
M280 P0 S90 ; Pin up
Every time I turn on the printer and connect through Octoprint the BL Touch will get exercised. Unfortunately there doesn't seem to be a way to test that the pin is actually down before the carriage starts moving down.

Anyone know what could cause my RAMPS to start messing up arduinos?
I use a $9 C.H.I.P (www.getchip.com) as a printer server running repetier-server to control my 2020 i3. Had been working flawlessly for a month, then suddenly last Thursday it shut down with no warning with 10 minutes to go in a print. Since then I've had a pile of problems. I reflashed the OS on the C.H.I.P re-installed rep-server and couldn't get it to talk to my printer. It would appear to connect - but couldn't actually send any commands. I can still print from SD but over USB things are really messed up.
When I connect by USB right to my desktop repetier-host just shows garbage coming from the arduino/RAMPS:
18:00:42.106 : No start signal detected - forcing start 18:00:44.592 : Jo6?F?J??%?M?y?K?f?*kX?H.,?P|fN?H7obvHa&??'Z]h.?g:}M?VS? 18:05:45.419 : ??
I happened to have a spare RAMPS/Arduino set on hand that I was going to use for the MPCNC I'm printing...and it worked just fine when I hooked it up to the C.H.I.P or straight to my computer.
So I figured it had to be something with my Arduino or Marlin. I reflashed Marlin and still had the same problems. So apparently that wasn't it. Then I swapped the arduino on my printer for the one from the other set (which was working fine) and it's now doing the same thing just giving garbage. I moved it back to the RAMPS it came with and it's giving garbage there now as well, even after reflashing.
So it seems any arduino I connect to the RAMPS on my printer develops some kind of problem with it's USB converter (remember it still prints from SD so the main processor seems to be working ok.)
I still have another spare arduino mega from other projects on hand...but I'm not about to subject it to the kiss of death from my Printer now
Looks like I'll need to order a new RAMPS/Mega combo...but I'm at a loss as to what could be causing this. It doesn't seem likely that anything is physically wrong since I can still reflash the arduinos so the USB-Serial bridge is still seems to be working.
Ok...it gets harder to understand....I'm still getting garbage if I connect the arduinos right to my PC and talk to them with rep-host...but connected to the CHIP rep-server can now connect and talk to my spare test board and the board for my MPCNC...but my original board still won't talk after connecting. And now my RAMPS is acting like it's not getting power but still has 12v on the inputs and the fuses show continuity...but no lights.
This is not my day apparently....

It sounds like the mega has some power issue, maybe a faulty voltage regulator on the mega. I have a bad regulator right now and my temp fix is a powered USB 2.0 hub. Is the amperage for the C.H.I.P. power supply up to the task, or does it derive power from the Ramps through the mega board? Some of my old USB chargers are rated way too low in amperage.
Are the MOSFETS on the Ramps Board touching each other?

Check in case the gear on the extruder is slipping. Sometimes the grub screws can work loose.
Check whether the V-grooved bearing in the extruder is rotating freely. These are quite cheap bearings and can wear out.
Check whether the nozzle is blocked (partly in your case as some filament is getting through). This is a bit harder to see directly, but maybe you can drive some filament through by hand. If you have some fine stiff wire such as welding wire or a guitar string, you may be able to run it through, but be careful to avoid damaging the liner.
Awesome, thank you very much, I will look into all that.

They are not an official sponsor. The forum thread was started by someone from Folger, but he has not been involved since the very early posts on it, and I think no longer works there.

Attach the black wire the remaining – screw/socket on the power supply (the 6th from the side of the power supply closest to the back of the printer assembly). Note: This will cause the extruder fan to run constantly, which will reduce clogs and jams in the extruder.

From the manual to deal with the fan extruder:
Attach the black wire the remaining – screw/socket on the power supply (the 6th from the side of the power supply closest to the back of the printer assembly). Note: This will cause the extruder fan to run constantly, which will reduce clogs and jams in the extruder.
I think the first attempt was to plug the hot end fan to the D9 Connector. Looks like it was an issue (maybe the fan stopped to early when the hot end stopped heating I don't know). But it could be great to turn on the fan only when required (and keep it running for a certain amount of time.
From Polulu schematic [reprap.org] we can see the D8 to D10 connector and on Marlin Firmware [github.com] we can see some variant of the RAMP Board (like EEB or EFB an so on).
And this is actually a feature of the Marlin firmware: [github.com]
So I was wondering if there is a way to plug the FAN to the D9 Connector and let Marlin deal with the FAN power on / off depending on the hot end temperature. If any one already tried this please share your thought.
If the manual state otherwise then, there should be a reason I'd like to hear
