No unusual noises. Not a new filament, actually I consider this to be my most reliable filament, well not anymore I guess. Waiting on endstop replacement to arrive so I can get back to troubleshooting.

Hmm, interesting. I don't think there is a clogged nozzle or anything wrong with the tubing because when I tell the printer to extrude x-length of filament everything is normal. All the other settings seem to be correct as well. Maybe it is too close to the bed. Unfortunately my y-endstop has suddenly stopped working. I think there is something wrong with the switch mechanism unfortunately...

Previously I have printed many objects with the current setting, however today all of the layers came out looking weird. Here is a picture of just the first layer:
Settings/info:
-PLA (1.75mm)
-190 degrees
-cooling fan running
-no heated bed
-speed= 30 mm/s
-extrusion multiplier= 1
-Sli3er
-blue tape (Recently changed. Sticking is not an issue.)
It looked like it might be over extruding so I t

Hello,
I recently printed 2 objects however the dimensions of both objects do not match the measurement of the object in the file.
First object should have been printed 40mm x 15mm x 40mm but came out 32.34mm x 14.50 mm x 46.50 mm
Second object should have printed 25mm x 25mm x 25mm but came out 20.42mm x 23.29mm x 29 mm
Kind of all over the place except for the y-axis, pretty close...

All of a sudden my printer has been printing objects with gaps in the perimeter layers. I Switched to a new filament but then I switched back to the old filament (which I know prints well) and the problem was still there! Also a small amount of filament started leaking out of the sides of the thermistor and block. I read that the tubing inside the bowden may need replacing so I have went ahead an

Ah, I see. No, I definitely know that the thermistor is the tiny glass bead, just mispoke! I unclogged the heat-break.
Upon further inspection, I now see that wiring on the thermistor has come apart! Since the wire is so fine I don't think it would be worth soldering, so I'm just going to order a replacement.
I'll give an update when I replace the thermistor!

Today I was printing with new filament and printed a bit too fast and jammed my machine. No biggie though, it's no like this hasn't happened before. I was disassembled the extruder and carriage to get to the thermistor so I could clear the jam. I then wanted to heat up just the thermistor using the hotebnd and push the jam out. However, when I went to heat the printer, the temperature reading nev

Thank you for the suggestions. Great idea to calibrate the the z-axis with the hotend on. That actually did change the distance displaced. It moved about an extra 8mm. So with that fixed, I managed to get the absolute best print I've ever done! Everything is fixed! For now...
Thank you!

Yes, well its more a a 3rd+ layer problem the second layer is acceptable.
Layer height: 0.3mm
First Layer height: 0.3mm
Nozzle diameter: 0.4mm
Z offset: 0mm

Okay, I have re-calibrated my extruder @ (i.e. 10mm extrusion is actually 10mm of filament going in) and the prints look better, however the nozzle tip is still rubbing against the top of the printing object. The rubbing is audible, and at that point I just stop the print because the filament isn't able to come out well since the tip of the extrude is too close.
Any additional suggestions?

Hello,
The current issue that I am working with my printer is getting the nozzle to not run into the print while it is printing. I have read a few other threads about this same topic and none of their suggestions have been a solution to this issue for me. Essentially, the nozzle is just too low.
Here is what I have tried:
1. re-calibrating the z-axis
2. Changed the 3rd parameter of _MAX_FEEDRAT

I guided the filament with my fingers and it extruded much smoother! I tightened the --um, I'm blanking on the name of it, but its made of the two screws with springs on them that create tension on the filament to pull it through. Although, now its so tight that the springs don't actually do anything, but I guess that's alright. My hobbed bolt probably isn't the best, but everything seems a bit b

When I extrude some filament while the nozzle is above the bed, here is what it looks like following the commands G92E0 and G1E50F50 (video: )
It does seem like the filament comes out inconsistently but the gears aren't skipping and the is no jam. Not sure what's going on.

Hello,
I had recently got my printer working successfully, until just now when I tried to print. The filament is coming out inconsistently, but there is no blockage and the gears to do not seem to skip. This makes it very difficult to get prints to stick (https://drive.google.com/file/d/0B7Qt9P6bsuKLaDlZZ3JoV0pDUzhvd3A3UDVnbWI4RWhNMXMw/view?usp=sharing).

Wow!! Check it out! Before is on the left, after is on the right. Amazing difference!
I changed all of the speeds in Slic3er to 50mm/s except the first layer speed... 35% which is what I used in the above image on the right
Here are my old Sli3er values
Perimeter: 40mm/s
Small perimeter: 70%
External perimeter: 90%
Infill: 40mm/s
Solid infill: 100%
Top solid infill: 90%
Support material: 45mm/

I was hesitant to try 4090 because its seems so much high than what is typically used, so I essentially started over at 700 and extruding 30mm at 50mm/min. Here are some calculations I used with the guidance of this website: if anyone is curious.
1st: 700*30=21000/1617.87
2nd: 1617.87*30= 4853.10/32.86= 1477.07
3rd: 1477.06*30= 44311.80/24.70= 1794.00
4th: 1794.00*30= 53820/31.04= 1733.89

The extruder doesn't seem to be chewing up the filament or causing it to slip.
I've had a clogged nozzle before but it currently does not seem to showing the signs that it had in the past when this was the case.
I am using a green RAMPS 1.4 and here is a picture from way back when the electronics were first being assembled:
Do these jumpers look alright?

Wow really interesting. I tried to re-calibrate the extruder and realized that when I tried to extrude 100mm of filament I am only getting about 22mm..so I changed the value in my Sprinter to (100/(120-98))*900= 4090 which doesn't make sense... I tried 900, but that barely extruded anything...
Has anyone else encountered something like this before?

I was just reading that an extruder calibration is recommending with every new roll of filament. Thanks for the suggestion, I'll try re-calibrating. All of the prints I've have been larger than this (the base only has an area of 1 in^2) so it hasn't been as noticeable, but I would that I've never really achieved a water tight seal...

Hello,
I am trying to print a small piece for a project I am working on. Since it's so small I don't mind using more plastic. I essentially want it to be a solid piece. I have tried adjusting the layer height, fill density, and the extrusion multiplier but I do not see any change in my prints. I am using sli3r to make these changes.
Please see the link to my 4 attempts at this print:

Hello,
I noticed that the M3 grub screws are not fitting my stepper driver pulley. My local hardware store doesn't have anything smaller than a M4... I'm assuming I need either an M2.5 or M2. Does anyone have any experience with this? I looked online but I won't know if they fit, and I'd have to buy, like, 50 even though I just need 2.
Thanks.

Thank you for all of the replies, yes I did mean J-head V6. I cleared the jammed today!! I used small drill bit to manually chip away at the plastic in the heat break. Then I used a wrench to lightly tap the drill bit through the jam and it cam flying out!! Yay!! No heat needed

Hello,
During my last print the fan on my hotend turned off and I was not there to see it, thus I have a crazy jam in my hotend... I've tried heating it and poking the jam through with a tool, but that didn't work. I read online that acetone can hep, so I disassembled it and have been soaking the piece with the jammed PLA in it but no luck so far. I heard that drilling through it can solve the p

I also recently discovered that a lot of my problems were caused by a conflicting values in the Sli3er software. What I mean by that is the value for the nozzle diameter and the layer height need to match (0.4 mm for me) otherwise this confuses the printer. Now I'm just working on cleaning up hallow print structures, its an endless challenge.

I found out that if the nozzle diameter value and the layer height value are not the same, then the printer kind of freaks out. This would explain some of my problems! Still working on improving print quality...
