My First Prints & Problems

20160226-1600 First attempt to print the PRUSA logo from the provided SD card (PLA_Prusa_200um_30M.gcode)
FAILURE: Print failed after printing the base plate of the logo. Extruder stopped working. Extruder stepper motor made weird repeating noises (clicks) but no filament was fed into the print head.
=> Loosened the extruder idler screws (the ones with the springs) a little (they now stick out about 15mm). Originally I had tightened these until I could not turn them anymore but I was guessing this was too much.

20160226-1700 Second attempt to print the PRUSA logo from the provided SD card (PLA_Prusa_200um_30M.gcode)
SUCCESS: Perfect print. Very happy.

20160227-1800 First attempt to print the Treefrog from the provided SD card (PLA_Treefrog_50um_3H.gcode)
FAILURE: Stopped the print a couple of minutes in because I had missed a blob of PLA that had stuck to the nozzle and that was deposited on the print after a couple of layers...

20160227-1830 Second attempt to print the Treefrog from the provided SD card (PLA_Treefrog_50um_3H.gcode)
SUCCESS: Perfect print. Very happy.

20160227-0900 First attempt to print Marvin from the provided SD card (PLA_3DHubs_Marvin_100um_1H.gcode)
FAILURE: 5 minutes into the print the printer just stopped...

20160227-1000 Second attempt to print Marvin from the provided SD card (PLA_3DHubs_Marvin_100um_1H.gcode)
FAILURE: the figure came loose from the printer bed after printing about 5mm
=> I think I forgot to reapply the glue after the previous failure. Applying glue and retrying...

20160227-1100 Third attempt to print Marvin from the provided SD card (PLA_3DHubs_Marvin_100um_1H.gcode)
FAILURE: the figure came loose from the printer bed after printing about 15mm (se we made it quite far)
=> I don't know what the problem is. I do notice that the part that printed is NOT perfectly planar at the bottom, it 'wobbles' (see picture).
I assume this could also explain why it came loose... don't know why this is happening though...
=> Decided to thoroughly clean the glass plate and reapply glue & ABS juice (not sure if this has any impact when printing PLA but assuming it can't hurt either)

20160227-1500 First attempt (on request of my youngest daughter) to print the Low-Poly Pikachu from Thingiverse via Pronterface (200um)
SUCCESS: Perfect print. Very happy. Had to use Pronterface to print though since my SD CARD reader has stopped working (see other thread).

20160227-1730 Fourth attempt to print Marvin via Pronterfacefrom (PLA_3DHubs_Marvin_100um_1H.gcode)
FAILURE: the figure again detached itself from the printer bed after printing about 5mm
=> Feels like Marvin does not want to be printed by me...

CONCLUSION
I'm already happy that the machine works since the bottle of ABS juice had leaked (almost completely...) into the box during transport so there were some doubts.
Overall I'm really impressed so far. I also started to really understand the fact that 3D printing is something you 'learn'. Great!
Some problems remain but I'm convinced that those will get sorted out with the help of the community & Prusa support.
My SD Card reader has stopped working (see other thread) and I don't trust the extruder (the prints until now I often ensures there was enough filament available since I don't trust the spool to roll by itself...),
Now I first want to figure out why Marvin won't print... a new obsession is born... 🙄

PS: I had to link to the pictures on my OneDrive, I could not upload half of the pictures on this site

Re: My First Prints & Problems

Hi Gerg

That's great, thanks for updates and pics.

PLA - you should not use ABS juice - PLA will not stick to it. Just use glue stick (see Josef's video: and also this page: http://www.prusa3d.com/material-guides/

I find it best to pre-heat (especially the bed) and wait for 5 minutes before printing. The heat takes a while to get through the glass. You could also increase the bed temp by 5 to 10 degrees after print has started. PLA will stick better the higher the temps with a range of 40 to 70 degrees. The other option is blue tape which can be printed on without heat, but 30 to 50 degrees gives great results for me.

I think this page will take on up to 3 attachments.

Re: My First Prints & Problems

Thats odd that you say your bottle of ABS juice leaked,

Every printer that ive received (ive gotten 3) has had just the bottle with ABS filament in it , and you add your own acetone. Was this something new?

regarding the Marvin, If you bed isnt perfectly level it can sometimes be tough to have items with such a small footprint stay attached to the bed, You can compensate for this by printing them with a Raft.

I contacted support and they weren't surprised that the juice was in the bottle. They were surprised though that the bottle was just 'loose' in the (outermost) box, apparently it was supposed to be inside one of the smaller boxes. To be honest I had also expected to get just the bottle with the filament inside it (it's what's mentioned in the shop). Perhaps it depends on your location (Belgium) whether UPS wants to ships such items and they adapt it to that?

Thanks for the tip. Would like to print it 'as is' but your tip allows me to at least do a proper print if all else fails. 😉

20160227-2030 Fifth attempt to print Marvin via Pronterfacefrom (PLA_3DHubs_Marvin_100um_1H.gcode)
FAILURE: we came very close but the figure again detached itself from the printer bed just before finishing the keychain ring

20160228-0900 Sixth attempt to print Marvin via Pronterfacefrom (PLA_3DHubs_Marvin_100um_1H.gcode)
FAILURE: the figure again detached itself from the printer bed after printing about 5mm
=> This time I applied Peter's tips (no ABS juice and an increase in bed temp to 60°C) but it failed again... I'll keep trying. 😎

Hi Erron

Liquids cannot be shipped by air. So outside the EU road transport system, you have to buy the acetone yourself (it is explained on the shop pages).

A while back we had a similar situation with users having failed prints with Adalinda (the dragon). I think what happened at that point was that they moved on to their own sliced prints which were fine; those who then came back to the dragon found that they could print it with no problems.

This was possibly because they had become more familiar with the printer and how to set it up.

Can I suggest you do the same? Go slice and print a few other models using the SD card at 0.2mm layers and then return to this one.

Re: My First Prints & Problems

Use Kapton tape if you REALLY want adhesion. That stuff with ABS juice on top will bond very well to both ABS and PLA, often times TOO well.

The only problem with this approach is that it's kind of a pain to apply the tape, but outweighed by the benefits if you can't figure out another solution.

I would definitely try using the brim feature, though, before going further. Put about 5 lines for your brim and that should do the trick. Just make sure that the bed is leveled appropriately and that those first layers are really bonded to the bed.

I have Kapton tape (8" wide) on my clone which has an aluminium build plate. I simply use glue stick with PLA and it works almost identically to glass.

Applying the tape is not a problem if you have a mister with wet water in it; a light spray and squeegee after.

Personally I don't see any advantage of putting Kapton onto glass. Blue tape on the other hand is good on glass; also helps levelling.

Re: My First Prints & Problems

Peter,

I too only need glue applied to the glass bed for my PLA prints to stick. But, there is definitely better adhesion to the Kapton tape. Often times you will actually have difficulty getting the print off the tape, so it is the ultimate solution if you can't get it stick otherwise.

I haven't actually used the wet method. I use a roller to apply the tape but your way might be easier.

I use Kapton instead of blue tape with a heated bed because of its heat resistance properties. I don't know how painter's tape would do at the 100C you need for ABS, whereas Kapton works fine at all temps. But it's just a matter of preference I guess.

Re: My First Prints & Problems

Blue tape for PLA only not ABS.

Blue tape loses its stick at over about 50 degrees; it really is intended for non-heated beds and provides excellent adhesion for that purpose. But I am a bit of a miserly person. Why print at 60 degrees, when you can achieve the same results at 40 (or even 30) degrees. The heated bed is the single biggest power drain on the printer. Why not save a few pennies?

The wet Kapton tape application is so simple. Water (with 1 drop of washing up liquid/ dishwasher rinse aid) - light misting on the bed and the Kapton tape can be slid around. Squeegee with a credit card (or similar) and it sticks firm. Heat for a few minutes. Done.

As mentioned, I use glue stick on Kapton and glass, so I get the same adhesion to glue on both.

Re: My First Prints & Problems

I agree, it's probably best to print PLA at room temp with blue tape. I did that when I first started printing. It was an Ultimaker original without a heated bed and blue tape worked like a charm. It was when I tried printing ABS without a heated bed that I realized the need for heat.

Haven't really gone back to non-heated since then but I might consider it again.

And I'll give that squeegee trick a try.

Have you tried just using the ABS juice directly on the Kapton? I use the ABS juice on the Kapton for both ABS and PLA. It seems to work equally well for both.

Re: My First Prints & Problems

I only use the Kapton on the clone and in all honesty, I don't think that would stand up to printing at ABS temps.

In all honesty, it was a good starter printer for me; taught me a lot, but the quality is nowhere near to the i3. I have spare i3 frame, extruder etc, so I am thinking about rebuilding the clone as an enlarged original.
