Am a new Palette 2 Pro user and am very happy with my first 36 hours as an owner. I initially completed two single material four color prints through connected Canvas (modified an existing octoprint instance) using a Prusa i3 MK3 to get my initial setup done.
Having shaken out configuration and connectivity, I moved to Chroma as I am a long term Simplify3D user.
My experience has been good, but certainly not flawless I have suggestions for fixes to problems I encountered that might help other new users in the future.
1. The Simplify3D end script for a Prusa i3 (and maybe other printers as well) begins with a "G4" code (no paramters) to allow existing moves to complete before shutting down the extruders, fans, etc. Chroma throws a syntax error when processing this gcode file.
But, Marlin firmware claims a "G4" issued alone without parameters is valid and is effectively the same as a "M400".
I changed to end script and replaced the "G4" with a "M400" which Chroma accepted. But, it would be a simpler out of the box experience if you modified your parser to accept this valid syntax.
2. My only failed prints have been due to first layer transition tower adhesion.The first layer tower outline sticks well as there is a parameter in the printer profile to set the perimeter print speed. The model's first layer also adheres well as Simplify3D specifies a first layer slowdown by default in its profiles. But, when the first layer of actual transition extrusion occurs within the tower, it's mm/s rate is much higher than either the tower's perimeter or the model's. This first layer does not adhere well and is usually ripped up by the second layer when it prints.
To work around this, I have been entering the printer's tuning menu and slowing the speed down to 40% until the first layer is completed. But, this is a hassle and should not be necessary.
Thank you in advance for your consideration.
