transition problem not realy good

hello i’m french. after 4 kilogram of melted plastic I'm losing my patience. to start my printing is simple, the writing is black (0.4mm thick) the rest white.

the result is identical with other STLs. I have trails in my color (there, in white) and the higher the print, the more flagrant it is. I put in transition 150mm then 300 then 400 but nothing changes there.

I tried to reset the palette calibration, the problem is the same. I go through canvas and the canvas hub. Thank you for your help.

Thank you ! I tested in gray indeed it is less visible. I will therefore switch my printer to full metal in order to limit residues;)

Hi Bastié, thank you for contacting us. I am sorry to hear you are frustrated but hope we can provide more assistance here.


The color issue you are seeing here doesn’t look to be related to calibration, and I suggest to avoid resetting Palette again so that you don’t have to tune your printer profile once more. If this was calibration related you would likely see colors begin transitioning too early or too late, or have layers mismatched in colors.


This looks primarily to be color bleed, and you have taken the right steps by increasing the transition length. Unfortunately black filament does tend to bleed quite a lot, and some residual black filament may stay in your nozzle despite the longer transition lengths. While we do allow for larger transition lengths in Chroma to help with this, going from black to white is still a great color contrast. To purge a nozzle of black completely can still be challenging, which is why for prints like this where you’re going from a very dark/pigmented color to a very light one, you may see better results using dark grey or even translucent black filament. With these colors and a higher transition length (200mm or more) you will still get the visual contrast in the print. Sorry if this is not the answer you are looking for but I hope it provided some further explanation for your issue.
