G-Code doesn't load properly in Cura 15.04.4

Recommended Posts

Hello, I'm new to this printing game, so obviously have to find out a lot.

The printer is a UM 2 ext.+ btw

I try the search function of course, but will give it a go for support from this lot if I can't find the right answer.

I'm trying prints at the moment to figure out how the different settings work.

It's quite a complex hollow model with all kinds of angles, so if I get this right I've made my first steps forward to understand how it all comes together.

To see where it actually went wrong I'm trying to reload the G-code for this file (45 Mb) into Cura, but it only comes up with a bit of the top half of the model.

I tried through "load model file" and "Load profile from G-code", but the results are poor.

Am I doing something wrong or can't Cura handle my file?

Thanks in advance for you adequate replies

Hi @Erik-RS,

If you convert a digital 3D model, like an STL, into a g-code the file is being converted into a list with commands. That is basically what a g-code is.

A g-code is a text file which you can open in note pad for example or other similar tools.

When you reload a g-code in Cura a lot of data it previously used to create a visual representation is lost, so it can't show it the same image it showed the STL.

In the top right corner, you have the option to alter the view-mode from regular to overhang/transparant etc. One other option is layers.

It will illustrate the toolpath the head will cross while building up your model.

This is the only representation it can give you based on a g-code.

It loads every layer, so if it only shows part of the model you may need to wait a few sections before it finished loading the entire file. It can take a little bit longer than with a regular STL.

Let me know if this was helpful!

Hi Sander,

Cheers for the quick reply.

I understand the G-code thing and the way the model is sliced to build up the layers.

I want to check the supports in the printed file to make adjustments for the overhang angle to sort out problems.

Some pics:

The model imported as stl. With my luck my first project barely fits the platform and is a pain to position :(


This I see after loading the G-code


The layer bar at 265:


BTW: Are there any workshops/courses on working these machines and it's software in NL?

Just got the printer last saturday and would love to speed up the learning curve. Using it professionally, time is not on my side

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
