Cetus S3D G Code

Cetus G-Code

Cetus, you know how to read G-Code quite well. You earn another, “I’m impressed!”

The Cetus native operating software does a very nice job of 3D printing. However, it is a proprietary system. The user must run it the way Cetus built it. Variables are limited so operating options are also limited. I want to run a print without a raft. I can, but Cetus will add a bottom layer and a skirt I don’t need or want. It can’t be turned off. If I want supports, there are a few tweaks available, but not something like “from the bed only”.

There is a work-around. The Cetus team has taught their controller program to read G-Code to create a print from other slicer /control software such as Cura or Simplify3D

I see some newbies are having a problem understanding how that works. I have seen postings on forums that ask, “I can’t get Simplify3D to communicate with my Cetus printer.” Well, there is a good reason. It never will, directly.

The process requires configuring a program like Simplify3D to generate proper formatted G-Code for the Cetus printer. Many settings must be properly configured. Then the program is run. Generated G-Code is saved outside of Simplify3D as if it is going to be loaded on a memory card. The Cetus doesn’t have an external memory card slot, so the G-Code file is read by the proprietary Cetus computer software program and fed to the printer as if the Cetus program created the file.

The file is executed by the Cetus printer. You can’t see it run on either application. Simpify3D has no problem as it was designed to create G-Files for memory cards. Its live view was never intended to function when using a plug in memory file.

The Cetus application does show some information.

I was surprised to notice the Cetus program displaying the nozzle temperature for the entire print job when executing a foreign G-Code file.  I highlighted this in the lead picture. When running its own created file, the temperature reading goes away and is replaced by a percentage of variance from the intended set point. (A totally useless bit of information).

There is no on-screen abort button when running loaded G-Code files in the Cetus software, but I discovered the front “Initialize” button on the printer body makes an excellent panic abort button. Good to know if your G-Code is faulty. Cetus posts a warning when loading external G-Code that the machine may be badly damaged by faulty G-Code.

I don’t know what “badly” means, but it seems to me to be a bit of a scare tactic for neophytes.

The pictures here show the first G-Code from Simplify3D I ran on Cetus. Running G-Code on Cetus is a kind of Texas two-step. But just like the dance, practice makes perfect.
