very. I spent the last 3 weeks fiddling with the timing. If you are not willing to troubleshoot and work on it I’d go for a ready-built solution like the AMS. I like the challenge, but definitely underestimated it

Most of it was me not fully understanding what was happening in the filament swap gcode. Once I understood that I was able to tweak settings to make it work. Once I found out certain filaments are just trouble I have had better luck. Still working on getting it to be less picky.

the updated version in April is going to have sensor-less detection of where the filament is in it’s path, which will make timing a non-issue. Any Chameleon sold until then will have the hardware needed, and can be updated for free in April.
