I just got the Chameleon a few days ago and have been having problems since I started. I figured out how to use Prusa Slicer (I normally use Ideamaker) and I put in the auto generated gcode in the tool change section. The tip shaping is just not working properly. I was able to tinker with it enough for it to be removed and slide back in, but it becomes too wide to fit back into the hotend after about 5 layers. The ramming function is not working well either, there is always a string about 2 inches long on every tool change. I use and Ender 3 pro with the Micro Swiss Direct Drive with Hotend upgrade. I tried to use what another post with my setup said for the same problem, but it did not work. Can anyone help?
