On The Level with CETUS

Tiertime and it’s firmware and software have always marched to their own drum. It’s their way or the highway for most features. They do permit a very tiny smattering of Marlin-type G-code. I have been able to run the original Cetus with Simplify3D slicer. But some settings are very strange. Standard flow is 20 rather than the “standard 1”. 

I have become proficient with the Tiertime slicer(s) UPStudio and now UPStudio3 and use them for all CETUS printing.

This post I want to mention the unique “feature” of the original CETUS and it’s bed leveling. It has none. No mechanical leveling that is.

First impression of the new version 5 of Simplify 3D (S3Dv5) printing slicer is that it is like putting lipstick on a pig. It may dress the pig up a bit but it is still a pig. Albeit a pretty pig.

That’s not kissing the pig. It just my general reaction of this very overdue upgrade from version 4.1.2. 

So, this is my initial impression of the update and not a repeat of all of the new features. If one needs to know what has changed, read the marketing propaganda straight from the company web site HERE. Note: First Impressions are subject to change...

Nozzle Size 0.60mm

IMG 0925The everyday nozzle hole size for FDM filament printing is 0.040mm. It is the default standard. Not every printer follows the crowd. MakerGear uses 0.35mm as their standard size nozzle. 

Nozzle hole size is one factor that determines possible extruded line width, height and extrusion amount. Those are variables that are altered depending on size and strength of the item to be printed.

Bigger hole size is of course more plastic flow and smaller is less. But there are other adjustable variables that affect the actual flow amount. It’s all a game of balance and tuning to get the exact extrusion flow desired or required for a good print.

The smaller the hole size the more critical all the adjustable setting factors become and lowers the flow rate considerable amount. Also greatly increasing the print time.

Standard range for nozzle hole size is between 0.20mm up to 1.0mm on hobbyist machine with 0.20mm to 0.60mm (0.40mm standard) as the most common.

I have used the 0.20mm size nozzle on occasion. Used mostly for very small prints of very high detail. Also requires very long print times. 

Today I have been using the 0.60mm nozzle on a small project. I see that I have been missing some of the benefits of using the wider nozzle. A wider extrusion is laid down so fill-in and wall pass counts can be reduced and extruding run at higher print speeds. Ninety plus percent of my prints really don’t require printing with a 0.40mm nozzle. 

I now realize there is nothing sacred about the “standard” 0.40mm nozzle. It’s pretty much all purpose, but that doesn’t mean it’s the best choice for every print. 

I think I will be using the 0.60 size nozzle much more often. Especially where I don’t need super-fine layers and fine details.

The photo is a small box printed with 0.30mm layer height and a 0.60mm nozzle using PETG. The results are great! Looks like an old pair of blue jeans. The filament is Overture brand called Stary Night (blue). I can see the stars!

Cetus and PETG

IMG 0888I have a heated bed on Cetus with a glass surface placed on top. Hair spray is my adhesive. It generally works very well. But there are some “tricks” in getting a good print without using a raft.

The big issue with Cetus is there is no manual leveling of the print surface. A thick raft is used to build a level surface before starting the intended print. 

This takes considerable time and some wasted material. The material consumption is no big issue unless one is close to the end of the spool.

PETG is particularly sensitive to everything being “right” with initial layers.

I use G-code produced with Simplify3D. It has much better control of variables than offered with the stock UPStudio slicer/print software. There is a new Beta for UPStudio which shows promise but stopped working on my WIN10 PC.

UPStudio is still required - to load 3rd party G-code to Cetus. Simplify3D cannot communicate directly with Cetus.

PETG extrusion temperature is 150C. with a 90C bed. I am presently using 0.25 layer height with +200% for the first layer (0.50 height) This is required to help compensate for the un-level bed. I am using 100% extrusion flow with a 0.4 diameter nozzle. non-solid infill is set at 150%

These figures don’t seem extreme, and what I have found as necessary to get good non-raft PETG prints on Cetus.

Sone factors when set too high tend to push the Cetus extruder close to its flow limits. Missed steps (clunking) can be heard if pushed harder. This is the feeder gear slipping on the filament and cutting a notch. This will usually stop filament feed.

Travel (print) speed is also quite low with PETG, 2100 mm/m with under-speeds of 60%. Rather slow but PETG is also speed fussy.

Note Well:  These are setting that work for me. Your results will certainly vary. Use these settings as an example of where you may have to go to get satisfactory PETG prints on a heated bed Cetus.

Here are a couple (or more) of big item prints I have designed.

The tissue box I designed for my own office. The olive green one. Then I noticed a new but bare tissue box out in the music room where my wife provides piano lessons. Thus the white-ish box was born. When she noticed the new boxes, she immediately wanted several more made. Number 5 is on the Mamacetus printer as I write this. Print time per box is over 12 hours.

Next project is what I call a K-cup stackable pod rack. There are three here holding 27 pod cups. Less space by about 1/3 of the rotating wire rack I have been using and holding 3 more pods Another rack on top of these would equal the height of the wire rack. So 12 more pods in the same space. It's also a good excuse to design/print something.
