Am I stuck?

Yes, and no. Read on…

Since it is so new, I have been spending most of my time exploring UP Studio3 (for Cetus2) and running many test and real prints on my new toy. The pre-release Cetus2.

Just read the latest update in the Kickstarter forum of Cetus2. I am NOT a big Facebook fan. My pre-release Cetus2 is soon going to be a bit obsolete as the production changes were listed. UP Studio3 is also getting some improvements.

In this report I take a look at CETUS2 color change in the normal print process. 

I designed a small test bowl with eleven horizontal stripes. Then I created a second version where I divided the bowl into quarters creating 44 sectors where I could alternate the colors within each row.

The lead picture displays the three variations of prints that were created.

The bowl on the left (#1) is a standard alternating color change in layers. This is the easiest print as there is no color purge required between layers. The short transisional color change can never been seen.

On The Fly

One of the selling features of the CETUS2 two filament 3D printer is its ability to change colors On The Fly (OTF). That claim is entirely true. But it took me some time to figure out how to do it well.

The primary ingredient with the CETUS2 is its very short “combined filament path" within its special extruder nozzle. The two filaments are introduced to each other (for single nozzle extrusion) very near the exit point of the nozzle.

In other articles, I mentioned the stringing, strands of light filament threads that are dragged out from the FDM print as the printer nozzle makes a non-printing jump move away from the printing surface to a new start location. It is caused by hot plastic flowing from the nozzle after it has been commanded to stop the flow.

Several adjustable factors are used to prevent this extra undesired flow. Retraction (reversing filament feed briefly) is the primary method to reduce or eliminate stringing. Temperature settings, retraction speed, retraction amount, pause, wipe, early stop, the list of “tweaks” seems endless. Sometimes it is an art rather than hard science to get the correct combination.

Is it ugly? It’s at least very LOUD. Red and Yellow seem to be circus colors perhaps. In any case it catches my eye. 

It is the colors I had so it was the colors I used. I’ll call it a party bowl.

The print was made on the CETUS2 and ran for almost 24 hours. Each one of the vertical color post are printed in layer sequence, one at a time. then switch colors and repeat on the same layer (0.2mm high).

My Cetus2 has me trying all kinds of silly "JUNQUE" print projects, but I am having a great time playing in Fusion360 CAD, UPStudio3, and Feeding CETUS2 directly (via USB) from Wand

I am learning a lot of new tricks with UPStudio3. Like moving support creation output between 3 extruders by moving entity codes between extruders. Don't ask me. Let Jason explain. :)

I currently have a problem getting eaisly removeable supports using mixed colors. Single colors no problem. We are still in prototype mode so a lot may change.

Yet another CETUS2 print project.

I received the Gecko file from a friend. I am sure it probably came from one of the on-line resources. I doubled the size from the original file and I believe I am responsile for slicing it into 3 layers. It is presently intended to be a two color print with the top and the bottom the same. Certainly it could be split into three parts for a three color print.

The reason I named this project "Oreo" is obviously the double "stuff" in the middle of the Gecko.

Update 3/3/22 - Since first publishing this review, I have learned much more on how to selectivly and efectivly modify the many variables in UP Studio3 3.2.4.  Printing three color bands are no longer an issue for me. It requires tuning the "Enitity IDs" for the three nozzles, enabeling each nozzle with the same printing abilities. These entites are not the same (fixed) for every style of print. They must be edited as required.  There is a need for far better and detailed sofware documentation. I hope this is a high priority before the official release of CETUS2.

I always blame myself for printing too much plastic JUNQUE. I like to design and print “stuff” that has a practical application other than a shelf decoration. Every person has their own reasons for print the things they like.

When I put CETUS2 together, I needed to check the power supply to make sure it was set to 115 volts for the U.S.A.  The power cord that was included was a 220 volt plug not for use in the U.S.A.

I posted the very first print previously. These are more first prints. Everything here but the first red and white print (center rear) and the frog are my own designs. Even the 20mm four layer test cubes. Nothing too original about those. Ha!.

Bottom left is a 2-color coaster for quilt makers. It's the square in square in square pattern. Next right is a 4 layer test cube. Next right are two small green brick walls with recessed blue morter joints. Setting on top is the two color frog. Far right first row is a blue bowl with yellow stripes.
