My first ever 3D print didn't work, but it wasn't the machine's fault …

Hi all 🙂

Well I excitedly unboxed my Robox this evening and couldn’t wait to get it to print something! So I selected this from MyMiniFactory:

https://www.myminifactory.com/object/sphere-in-a-cube-1261

It all started well, but after the first 4 or 5 layers the printer started spurting liquid plastic into the centre of the cube and it started making an awful mess! 🙁

I thought it was simply a print error so I started the print again … and it did the same thing!

I then realised that it’s probably an error in the 3D model as it would appear the sphere doesn’t actually touch the base, so the printer is trying to print a part that’s floating in mid-air!

Is this just a duff model? Or is there a setting I need to use to make sure the sphere is firmly attached to the base plate – using some additional material that I can cut away afterwards?

Many thanks for your help!

An excited … and slightly puzzled David with his new toy, err 3D printer 😉

If you turn on supports it will work. It will also fill up the square with a support matrix that needs to be removed.

For a first print i would recommend a torture test. There are several on thingivers. I like thing:1313497 but there are a lot of others. Than print a square or pyramid and check it’s dimensions. Than print a Yoda in high resolution. Try thing:1162185. I use a natural PLA with no infill. This is impressive.

Go to Roboxing ( http://www.roboxing.com/ ) and read getting started. Roboxing has a lot of good advise on use of your new Robox.

Now go and have fun.

Hi Henry,

Thanks so much for your quick reply!

I knew there had to be some simple explanation … I will experiment with the supports feature and report back.

Thanks again!

David 🙂

PS. Strangely the next object I printed (a cube with hollow walls) printed automatically with the support material - perhaps it was somehow saved into the model?

@henry, I have been using the printer for 10 months and didn’t realise the roboxing site exists. thanks for pointing it out. It’s a good refresher to learn the getting started section as it takes some of the guess work away; particularly fine-tuning the height calibration.

The maintenance section is also eye-catching but clicking into it reveals it’s work to be started. I wonder if there is anything out there detailing regular maintenance procedures in order to keep Robox well oiled.

e.g. has any one done a video on how to lubricate the various axes? The manual says it should be done every 200 hours of operation. Well, I have never done any. 🙂

@williamha

same question here: a video on maintaining robox would be very helpful,
an automated warning system on AM also.
