One Prime Tower to Rule Them All

I know this has probably been addressed but I can’t seem to find anything specific to the H2C.

I understand the prime tower is necessary however, is this size prime tower needed or is there some setting adjustment I should be making to make it smaller? I do not want to negatively affect quality so if it needs to be this big to assure the best print then so be it.

Yeah, you scroll down on the settings in the second picture.

I assume you mean under the Prime Tower Settings. Which setting should I change?

I’m very interested to see what Prusa are doing with prime tower removals - just having a tiny off bed prime - I hope it works out well enough for them for it to finds it ways into BambuStudio as an Option.

Start by clicking the purge mode button next to Project Filaments and select Prime Savings. Next you can play with prime tower parameters (under Others) with Infill Gap and Rib width to reduce its size and make a test to make sure your model will end up OK.

On H2C I don’t play with purge volumes as unless you use more than one color one the left and/or more than 6 colors on the right there will be no change in colors so no need for purge volume.

Edit: In your model, not sure what color7 is but it calculates at 0g and being apparently so close to color1, is there any way you can get rid of 7 (or 1) and end up with a 7 color model (no purge) rather than 8?

Color 7 is the BL Support Interface for PLA/PETG on the left nozzle and so reflects 0 grams in the model but 12.7g over all .05g support/12.65g tower.

I just noticed I took the screen print after I added a 7th color, Dark Gray. The actual printed model in the picture was with 6 colors.

I also had an issue on this print where Color 4 Green was mixed with Color 1 Black to the point where the areas that were supposed to be green printed out mostly black on the actual model (the original version I printed with 6 colors had Color 1 as Black and not Gray). I have a separate thread to try to figure out why that happened.

Normally I would play with some different setting to see if I could reduce the size of the massive prime tower but this print is almost 62 1/2 hours so trial prints are somewhat prohibitive.

Don’t try to print that one but just add some primitives in BS with some bit of color to see if they turn out OK. With H2C and no change of colors you can really reduce the prime tower to a minimum

Good idea, I’ll need to try that. I made some changes to the model so was going to print at .24 layer height to test instead of the.08 of the previous.

I will say the .08 really came nice
