I have to proclaim that hobby 3D printing is not an enjoyable pursuit for the  mechanically and technically challenged. One must be 100 percent committed to being fully self-motivated and self-sustained with all hardware and operational configurations and repair/maintenance needs.

Here are three of my ten (and more) of my 3D printers. One (not shown) is a duplicate (still in the box) of the Tiertime Cetus2 on the right in this photo. I also have a 3rd Cetus2 which is the prototype stored in my workshop. I have several UV Resin printers in the workshop.

It's nearly SPRING and time to tune up the CETUS2 for the seasonal 3D Sprint Speed Trials" (3DSST), where FDM 3D Print aficionados vie for title of "Fastest Printer East of the equator. Or something like that.

I am entered in the local 2 color single nozzle "sport" class with the new CETUS2 model and my new VELOCITY stacks. That will make it much FASTER.

Actually, the velocity stacks are just for show, but they do reduce the air intake noise. Mine are made from ASA plastic which is lighter weight than standard PLA. 

Running test trials now to determine just how fast I can push these new intakes.

I have posted a copy of the .STL file on my TEDEX Forum so you can create a pair of velocity stacks if there are 3DSST trials in your area... and you want an advantage.

Mt production version of CETUS2 died suddenly is the middle of a long print. Dead stop in mid-stroke. My new baby CETUS2 has SIDs!  (Sudden Infant Death)

After several email exchanges with Jason Wu and Fannie Zhang at CETUS2 (Tiertime) support, (Yeah, Jason finally has visible  help) it was determined to be the controller mother board. Apparently my failure was not the first.
