Description

The Snapmaker U1, with its multi-color and multi-material tool-changing capability, is well suited for printing colorful objects such as figures. Most U1 users are not printing parts that require strict dimensional accuracy. The Arachne wall generator better supports this use case than the classic wall generator. This change also brings the U1 process in line with other Snapmaker printers, such as the J1, which inherits fdm_process_common and defaults to Arachne.

Tests

This is a default profile change. I made the change to the profile and all Snapmaker U1 processes are now defaulted to Arachne.
