I recommend turning off the Randomize starting points checkbox. I hate that setting.

LOL... nice spool holder you got going on

Hello,

Thank you all for your inputs. While trying another attempt to print I noticed that the extruder had some difficulties pulling the filament. I decided to elevate the filament and the printer is doing much better!!! I was able to print the same cylinder that failed yesterday and another print that previously had failed.

The little creature from thinkverse still has issues, after printing the base the next 3 or 4 layers shifted.

I used the .3mm profile. 200/100 degrees.

*** Is this a normal print for this profile or do I need to adjust the flow of the filament again.

Thanks in advance for your help.

Would you mind sharing the STL file you guys use to test the printer before shipping it? Maybe everybody can use it as a reference point for calibration. Also, please let us know what Slic3r profile you are using.

I followed the instructions to adjust the Y-Alignment and belt tensioning. I tried printing a creature using the .3mm profile and my new filament profile and the printing shifted.
I tried printing a cube and a cilinder using the calibration settings and the cube was ok, but the cilinder shifted somewhere at 1/3. Bot are 20mm x 20mm.
I think that I have followed all if not most of the calibration steps. But still not printing properly.
Any help will be very much appreciated since Solidoodle customer support has stopped replying to my e-mails since last Monday. I wonder if solidoodle prints a test before shipping the printers.

They say they test the machines, but with the amount of people having issues day one, some if not most slip through without anything but built, then shipped.
That's not true at all. Must we show pictures of our assembly line to close this silly rumor? Honestly, our building is shaped in such a way that a printer cannot escape the building without being pulled through the testing department.

have you tried the set screw for the y axis on the back wall? it connects the vertical belt to the stepper... mine always loosens off giving the symptoms you see here... has been 20-30 prints since it happened at the weekend again... my set scre had completely come out and was found lying in the bottom of the SD
good practice to nip round with an allen key and tighten them all up...all the best !

Maybe you should get some loctite?

I agree , likely a set screw or some other mechanical binding going on.

the shift is a mechanical problem... too much ot not enough belt tensionning .. or/and not enough lubricant on rod

OR there is a hard point with your filament/spool that block the hothead move sometimes...

I'd say it looks a little more like you are overshooting meaning maybe your belts aren't tensioned quite right. I see some overhangs that would look like retraction but on a box like this retraction shouldn't come into play. Look for belt tensioning, I think it's on the solidoodle vimeo page or I'm sure Ian has covered it here or there. Search under x and y backlash as well.

You're getting close, hang in there.

Thank you very much for your inputs. I used the alternative mentioned in the “Extruder Calibration” post about changing the “Extrusion Multiplier” setting (that is the same parameter you change in the Flow Rate post) on Slic3r and I printed a test cube 20mm x 20mm following the instructions described in the “Flow Rate” post (using the .3mm Slic3rprofile). I was able to get a 0.42mm wall.

So far I have: level the platform, adjusted the z-screw, cleaned the platform, and adjusted the filament flow.

It looks much better but still I can see some ridges on 3 of the walls. Just one face has a really nice alignment. Is there anything else I can do to have a better quality?

Thanks again,

Hi Crazybear, You are definitely extruding too much which is more than likely what caused the shift in you first pic #2798 too much filament was deposited and caused the print-head to drag and lose steps here is a vid showing how to calibrate the extruder --> http://www.youtube.com/watch?v=JZGdMc2ebPo also check here ---> http://wiki.solidoodle.com/extruder-calibration other then that the only thing I notice is your z height may be just a tiny bit high but if that is what it takes to get it to stick don't change it until you have more experience with the printer also from time to time you may have to re-level the bed.

I suggest starting out with the .3mm profile until you really understand the printer. Printing at .1mm can take some more finesse . Once you feel comfortable with the slicing software and the mechanics of the printer then move to .1mm printing.

Give your kapton tape a once over with some isopropyl alcohol or look into the super cheap and highly effective 6"x6" glass + hairspray + binder clip mod.

That being said, it looks like your printer is pushing out to much plastic. In slic3r you can adjust this by lowering your extrusion multiplier.
