Hello. I go this a few days ago, and finally got around to testing it out today. The chameleon, as the title states, is installed on a K1 Max. I have gone through the forum here looking for solutions to my issue, and I came up empty. I have learned how the unit works, and I just can’t get it to print. When I start the print job (the item from Printables that comes with the profile) it feeds the T0 filament, drops a blob of filament onto the bed, makes the purge line, and then starts to print the first layer of the object. When it gets to the object it is massively under extruding and making lots of noises. I have checked for excessive tension at the chameleon, but I don’t know exactly what I am looking for. Before I print lots of little pieces and start rebuilding the brand new chameleon, I want to know if I am on the right path. I have bypassed the chameleon and I am currently printing an object that I sliced in PrusaSlicer, though not with the same profile- I think I got this profile from EmbraceMaking. It is printing just fine, though I had to manually turn on the fans (I will check into that later). Does this video help with pointing me in the right direction? I am looking forward to multi color prints, and I feel like I am so close. Thanks in advance for any help you guys can toss my way.

This might be a silly question, but what should the "g-code flavor" be under Printer Settings/General? I feel like I researched this at one point for the K1 Max, and Creality said to use Marlin, but mine is currently set to "Klipper".
The PA is being set here with a custom g-code in the filament setting
So just make sure you delete this ^

First off, if you have a blob you need to lower your Load time a tiny bit. maybe 0.5 seconds
You say T0 is under-extruding.
Can you check if the filament is able to move freely in the chameleon when T0 is loaded and ready to go? Manually load T0, and when you stop moving it the filament should be able to slide in and out of the chameleon relatively freely.
If you still feel grip then either your cam is not going to the right positions, or possibly your tension sliders need to be changed. Something is preventing that path from opening up all the way.
While your chameleon is not mounted run it to each of the 4 positions. Is the notch on the top of the selector gear at exactly at 0, 90, 180 and 270 degree positions? If not, your cam might be bad, easy re-print if so.
IDK if you saw, but I have somewhat of a guide for the K1 Max
Not sure what is happening there, but it has nothing to do with the physical 3DChameleon. That's clearly a slicing/configuration issue. We've seen a couple report that the printer is receiving commands to change the pressure advance, which isn't correct. Can you change filament profile to a local Generic PLA or PETG (whatever you are using) and see if that changes it? The profile I saw was injecting an M900 command with a pressure advance of 30, which is a lot higher than the .04 it's supposed to be, which was causing the issue. (Edited for correct PA.)
