Re: Glass Fail!!

My Rostock has almost 30 days printing time on it, and I've only had one occurrence where some chips came out of the build plate. I've flipped over and been printing on the other side since about 22 days of print time. That's primarily what I was wondering; my chip is around 30mm x 60mm—quite large...

Re: Glass Fail!!

Yep I have had this problem. I no longer use *any* force when removing prints from the bed. I put them in the freezer for a few minutes and let them pop off on their own. I don't think this solves the problem completely. I tend to see the build plate as a consumable - it's only good for a certain am...

Re: Under-extrusion on tall prints

Well the print with the new nozzle seemed to complete without issue, other than there being a lot of stringing - I ran the retraction at 1.5mm.

Re: Under-extrusion on tall prints

OK I am beginning to suspect that my nozzle is clogged. This is with 1.5mm retraction:

I have just switched to a new nozzle, will see if that solves things.

Re: Under-extrusion on tall prints

I think I'd pass it M84 to disconnect the motors and try turning the extruder by hand while moving the effector around. If the resistance increases dramatically when the effector gets to the height where you're having trouble, it should be related to the Bowden tube routing. If it doesn't I'd think...

I just re-ran the print with my aforementioned changes and had the same issue. http://i.imgur.com/x8H6Cta.jpg I found that if I reduced the print speed to 8mm/s, the extruder seemed able to function again, but anything higher than this resulted in ...

Re: the biggest problem for me is....

Hey John I suggest wearing a glove if you're going to use your fingers to remove filament from the hot end - eventually you'll slip and it's a nasty burn! A couple of things you can do to reduce the filament flowing before you're ready: - Wind back the extruder by a half-turn or more. This will redu...

Re: Under-extrusion on tall prints

TLDR of my below post is as follows: 1. Stepper current too low - raised from 130 to 150. 2. Extruding too fast for hotend - e3dv6 LITE - reduced print speed from 50mm/s to 35mm/s. Read on if you want the details! ------ Another thing to consider is that you may have turned the extruder drive down t...

Re: Under-extrusion on tall prints

I have a feeling it can be remedied without changing hardware. What are your print speeds and retraction settings? Temps? Does the part geometry get thinner as it goes up to the top of the ears? The part doesn't really get much thinner toward the ears, the entire thing is about 10mm thick. Settings...

Re: Under-extrusion on tall prints

How long is your Bowden tube? Mine is such that, while I was building the machine, I had some serious question whether it was going to reach the entire build plate. If that is the problem and you can get a sufficiently long Bowden tube, you also have the option of relocating the extruder drive abov...

Re: Under-extrusion on tall prints

There are some good options for upgrades; if you want to pick up a geared nema 17 you can mod the ezstruder or use one of the designs based around that motor. Or if you're pressed for time to get that print done, you could print out a standard Greg's/Wade's style geared extruder from thingiverse. T...

Re: Under-extrusion on tall prints

Another point - I recently switched to a different filament supplier. The filament I am using now is exactly 1.75mm in diameter. Previously, my filament was 1.66mm diameter. Is it possible that the thicker filament is causing more friction in the bowden?

Re: Under-extrusion on tall prints

When the hotend is up higher, the filament has to take a more bendy path through the bowden tube, increasing friction. Meaning it needs more pressure to extrude. I'd guess that your extruder motor is getting overwhelmed at those upper areas. Are you running the stock ezstruder, or have you upgraded...

Re: Fine tuning retraction

Is anyone out there getting string-free prints with Z-lift ON?

I would love to know your settings! I'm not making much progress on getting rid of my cobwebs.

If I turn z-lift off, the cobwebs go away, but I want to have it on so I can print supports without them being knocked over.

Re: Fine tuning retraction

Update - I'm confident I have solved the jamming issue. Last night I was able to run a fairly monolithic print with no stoppages whatsoever. Correctly calibrating my thermistor, and reducing my fanspeed to 50% means that the temp stays solid and everything runs nicely at 50mm/s print speed. http://i...

Re: Printer stop by half

It looks like a 'clean' stop - as if the printer just switched off, or the print was cancelled.

Can you post your STL and the GCODE ?

What slicer are you using ?
Are you printing over USB or from SD card?

I decided to go back to basics, here's what I've found: 1. My thermistor calibration was way off. It was running about 20C cooler than what I set it to. So my prints at 195C were actually hitting about 175C. This might explain the jamming/unjamming - the hot end would have been barely hot enough to ...

I suggest against dismantling the power supply unless you really know what you're doing. Better to just replace it, they're cheap enough.
