Hello all!

I am near perfection with this print, but wanted to know if anyone had noticed that in the model there are 7 walls between the ball and the distance bridges features, yet when printed, only 3 of the walls actually print. I've noticed this with all my prints and with all the makes I've seen posted here. Can anyone explain this?

ctrlV - in reply to omslice

your nozzle diameter defines the minimal wall size.
the slicer has also influence.

omslice - in reply to ctrlV

So what is the maximum nozzle diameter that will print all 7 walls?

since the smallest wall is 0.1mm guess what?

Makerfarm Pegasus
PLA 1.75
180/65 for 1st layer, 175/60 for others
Slic3r 1.2.9
USB
.35 nozzle diameter
.15 layer height

I'm still fairly new to 3D printing but I have had some fairly decent success in printing things in the past. I've noticed that a lot of times on prints with a large base I'll end up with a lot of bubbles on my first layer and it tends to make the next couple layers above it appear messed up as well but I haven't been able to fix the problem. whenever I print a small test cube I generally don't have any issues with this, only when there is a bit of space. I attempted to print this model but since it was one of the "larger" prints I ended up with bubbles on the first layer that messed up a few of the features of the print. By the time it got to layer 6 it was pretty even on the top but the features like the "V3" and "ctrlV" are still messed up since they are supposed to go through all layers but got messed up on #1.
Any suggestions on what I might be able to do to fix this? I've tried changing the temperature and print speed and the z offset but not much luck.

Simplify3D 3.0.2
USB
Nozzle diameter: 0.35
Extrusion width: 0.48mm
Retraction distance:1.00mm
Retraction speed:30.0mm/s

ctrlV I have been using these models since version 1 keep up the great work.
I have tried a few variations of settings but the above has given me the best result so far.
Any suggestions, what I am puzzled with is the holes are smaller e.g. 3, 4, 5 are around 2.8, 3.7, 4.8.
The base plate outside corner to corner is 100mm but only 1.5mm thick.

thanks!
the layerheigth has no chance to go to 2mm.
holes can be difficult for the slicer, do a search for polyhole to get more informations.

Test your 3D printer! v3
by jkuner

do you have a fan?

I have the stock fan on the hot end. I have thought about upgrading or maybe putting a desk fan on the prints, but haven't tried that yet.

Tevo Tarantula
Pla @ 195/50
.1mm lh
30% infill. 6.5mm retraction
1.2mm wall thickness
I did not print with cooling as i havent had a chance to install fan duct.
Cura 2.1.2 via SD card

So not sure where to troubleshoot from here overall it printed pretty well. Things that i notice initially are the bridge print needs work. The min distance wall only printed 2 sections
Also all the dimensions seem to be off. I measure about 92mm on build width. The circles all seem to be near .5mm small but perfectly formed. Spike is also short.

hard to see details on the photos.
here some guesses

  • objects looks molten, try with lower temperature / speed
  • some strings / blobs = more retract
  • does this happen with other material?

benpenguin2 - in reply to ctrlV

I have only tried using PLA. Also if I increase the retraction distance do I need to adjust the retraction speed or any other settings as well to avoid any issues? Also there are a lot of different speed options, would you like me to send screen shots of all the options or are you familiar with the advanced settings in MakerBot Desktop?

try to change retract speed to 100-250 mm/s (limited to 100?), go up in 1mm steps until holes appear. try to fine adjust in 0.1mm steps.
it seems the smart extruder has an extra restart distance which is set to 0.1mm, try 0.
you can duplicate the high profile and reduce all extrusion speeds to 50%.

Okay, I just reduced each extrusion speed by 50%, changed the extra restart distance to 0, decreased the temperature from 205 to 200, increased the retraction from 1 mm to 2 mm, and increased the retraction speed from 50 mm/s to 100 mm/s (the maximum). I am thinking about printing just a small cube, as opposed to reprinting the quality test over and over again, and making fine adjustments to the retraction based upon that in order to save time and plastic. Once it seems the retraction is at a good setting I will print another quality test. Thanks for the help.

I tried to print a cube three times but had issues. It would not extrude at all and would just move around as if it were for maybe 10 seconds or so and then it would start to extrude but it was out of sync with the movement as if it were delayed.

go back to 205°C

So I increased the temperature to 205, no difference. I continued to increase it to 215 and still no difference. I then tried a different smart extruder thinking that maybe the issue was with the actual extruder, but no difference. It seems to move around for a little bit as if it is printing and then the plastic comes out afterward and it continues to drip out for a little bit after I cancel the print. Maybe there is an issue with the speeds and for some reason it can not take in to account the changes I made. Do you think I also need to adjust the travel speeds (as the only speeds I changed previously were the extruding speeds) or maybe there is an issue with the retraction (since it was increased) and it is attempting to retract more which is messing up the print process?

sounds like the extruder don't like the speed setting, go back to the original settings.
just try to reduce all printing speeds

So I changed all the setting back to normal and it is still having issue printing. I will check on it and there will be a glob of plastic on the nozzle and it will be rubbing it back and forth on the platform. Any ideas?

can you extrude plastic manually?

Great thing!
Can you please tell me how you created the numbers 2-4-8-16 (bridge print)?
They are being printed so well on my up! mini. Normally, the up! mini has quite a few problems with printing small letters/numbers.
Thank you very much!

these are 3x5 cube arrays with extrusion width 0.48mm

Can you please tell me few tricks how should I tune my printer? I have done this and otherwise it wasn't really awful, but especially the dome is uneven and texts are barely visible. I am really new to the whole 3d printing so I might be doing something surprisingly wrong :)

  • try to lower temeperature, lower in 5°C steps (range could be 160-230°C for PLA)
  • retract
    blobs = more retract
    holes = less retract
  • maybe try another slicer http://www.whoote.com/viewtopic.php?f=7&t=9
    CraftWare is very promising
Jun 4, 2016 - Modified Jun 4, 2016

I am new to 3d printing, have had issues with only a few walls, issues with ALL my fittings, and issues printing several objects at the same time. I am looking to print this to test my printer but, if any (or all, but really hope it does not happen) come out wrong, what do you recommend twitching on the settings? I am just looking for some feedback, or tips, to what may solve some issues.

if you have any questions please post these infos.

  • printer brand
  • printer model
  • print material
  • print temperature(s)
  • layerheight
  • slicer including version
  • printer connection (USB/SD/LAN)

there could be a lot of things go wrong, here the most common ones

your printbed is not leveled (should be better than layerheigth you're printing, e.g use a Micrometre)
your axis (Y/X/Z) clearence (with higher speed you also get problems with the moving mass)
your slicer and configuration (every slicer handles things different and could contain bugs)
retract settings (not correctly set you will see blobs or holes on every retract position)
to high temperature (small details will get overheated)

Ill post my hardware/software info, will let you know how the test goes after the printer is finished printing a different part.

what about the sources, to be able to remix for other diameters than 0.48 ?

which diameters you looking for?

0.4 would be cool for me.
After that, are we really testing the printer, or the slicer :-) ?

you can download the 0.4mm file now.
this will test both printer & slicer.

thanks, I will test that

v3!!!!!!!!!!!!!!!!

Thanks for taking the time to make this handy printer test!

first to like and comment 5th to collect
edit: first to watch and first to remix
edit edit: first to unwatch

  1. to print is open :-)

btw i think i like the credit card shape better just some feedback

not anymore :P
