I am attempting to print: Hot+Wheels+Complete+Bracket+System
I am receiving this error: Prime Tower is too close to others, and collisions may be caused.
I tried to move the tower around the plate to open areas but nothing will make the error notification close. What do I need to do to fix this?
Welcome to the forum.
A link to the model and/or pictures are always helpful.
I added the link to the original post.
A screenshot of the sliced plate youre refering to would be more helpful
Timelapse smooth requires a pt also
Yes, I changed the color of the pegs in the upper right to black. Additionally, the Tower was placed by default just to the left of the pegs, on top of the top part.
If this is the issue, can you give me a quick and dirty on the function of the Prime Tower? I know itâs used to âstabilizeâ the flow before working directly on your model. Why am I getting this error? What is the proper placement for the Tower? Etc.
Thank you for your help!
Prime towers seem to have a skirt/brim that makes their footprint bigger than it appears in the prepare tab of Studio. You only see it in the preview tab, though, where you see all the printed bits. Itâs easy to think the prime tower is clear but have it encroach other things when sliced.
But what Jon said is true - you only get prime towers when printing multicolor (if you enable them). You somehow changed filament colors and missed something or added something and itâs in a different color.
changing the colour of a plate shouldnt require a prime tower
Thatâs exactly the function of the prime tower. After a filament change (or apparently an image is captured but know nothing of that) printing in the prime tower gets temperature and pressure stabilized somewhat in the print head. I donât know what else but it can affect surface smoothness/uniformity.
Itâs not perfect. Manually pause a print and when you resume, it doesnât visit the prime tower. But it can also help grab bits from the print nozzle and get you a better print.
You can turn them off if you donât want to use one.
Proper placement is maybe a personal choice but I put them near the parts Iâm printing so there isnât much time between the prime and printing parts.
You say upper-right, this could mean the 3rd plate or the 1st plate - you did not specify.
I am going to assume you mean the first plate and the âpegsâ are the small round things.
If this guess is correct and you have changed one or more parts on the same plate to be a different colour from the other parts - this is the cause.
If you have two or more different filaments on the same plate a prime tower is automatically added (you can turn it off). This is so the constant swapping of filaments on each layer will be clean each time.
You can change the size of the prime tower and the position.
More importantly, if you want a few items in one colour, move them to a new plate. Printing two different colours for this purpose will slow the overall printing time vs printing two plates. It will take less time to print two plates than to print one plate with constant colour changes.
It doesnât unless you add things of a different color. If prime towers are on by default in your settings you still wonât get one unless you have 2 or more filament colors in your print.
Maybe Iâm not following what youâre saying though.
And waste much less filament. 
far be it for me to correct somebody with left and right
The best thing to do is to move the pegs to a seperate plate. This will save you hours of colour swapping which isnât really needed as the objects are not multi coloured.
Here is the summary from the wiki article.
In 3D printing, we usually need a prime tower in multi-color printing tasks or when the smooth mode time-lapse is enabled. After the tool head travels or purging the filament, some residual material may still be left on the nozzle. Enabling the prime tower can clean up the residue on the nozzle and stabilize the chamber pressure inside the nozzle, to avoid appearance defects when printing objects.
The placement is not usually a problem but the plate is pretty full and the models are rotated to fit which doesnât leave much room. Each part has a bounding box (Highlighted in yellow in the picture below).
If the prime box is inside of this bounding box it will generate this error. Itâs a yellow error so itâs only a warning and the file should slice and print without issue.
Thank you! The part about it being a yellow error helps.
Yeah, that one is annoying. Itâs overly cautious and in case you are printing by object. Itâs warning that the print head would hit previously printed things on the build plate.
Printing by layer means everything steps up a layer at a time and there are no objects to hit. Studio should suppress the warning message if no true interference and printing by layer.
But putting those bits on their own plate will save time and filament.
I agree that putting the parts on a separate plate would be the most ideal situation as its not really needed for this print. For future prints where one is needed you can also reduce the size of the prime tower to help with fitting it.
