First print problems

Post by artem » Sat Jul 11, 2015 4:22 am

I just got my kit assembled this week and have a small problem when printing my first print (image attached below).
Oddly enough this problem mainly occurs on one side of the print.

If any one knows the solution to this problem please let me know.

Little hard to see what the issue here is with that picture. Could you describe what the problem is and perhaps post a picture at a more reasonable distance.

If you look in the middle of the image you will see a lot of mess ups in the print each one of them is about 1 mil in size. I will do my best to get better picture tomorrow morning.

I have added few more pictures I took with $50 microscope.

This was printed with original roll of PLA that came to me with my MakerGear M2 Kit.

those are the start and stop of each layer. you need to tune your ooze controls better. are you using s3d? if so can you zip up and post your fff.

That suggests the platform isn't quite aligned with the nozzle: it's too low on the side with the ripples. Performing the platform alignment ritual ("leveling") should improve the results.

A good getting-started guide from last year:
viewtopic.php?f=3&t=12

If you're printing on bare glass, eventually you'll want to try hair spray to improve the first layer's adhesion. That won't cure the platform alignment problem, but it will eliminate a whole bunch of hassles you haven't run into yet. [grin]

I think Jim is correct and Ed has misinterpreted your photos (those are layer lines, Ed, not filament threads). But it is a good idea to run through that tips thread, especially to run an extruder calibration.

Turn off random start points in the layer tab if you have it on, change to choose start point closest to location. If that converts your defects into a more or less single line up one side, then that's definitely what it is.

First I would like to thank every one for reply.

I just want to post a small update of what I have done since then.

1) After spending more time researching I learned that I had small clog in my nozzle from day one which can be seen in my first image. It is a lot of small waves in each layer. After cleaning it now I get straight lines when I print.
2) Re leveled my bead 5+ times it seemed to be better but I do not notice much improvement in all of the small sample prints I have done so far.
3) Got my 2nd small clog in the nuzzle after doing about 15-20 small 3-10 min prints to calibrate parameters for my 3d printer.

You need to run a filament wiper if you're clogging that often. I just use a piece of papertowel dabbed with corn oil folded around the filament and clipped with a small binder clip. It is loose enough to slide easily (sometimes under its own weight).
