Fixed a bug that could cause an empty Print Summary screen after proceeding through the "What do I do now?" instructions with Reduce Memory Usage enabled

Fixed a critical issue introduced in the previous release that could result in a cryptic error message and a failure to process the print

Optimized memory usage when re-generating transition towers

Fixed a bug where the print summary screen could be blank

Added a new Wanhao Duplicator 6 printer preset

If you're using this printer, you can change your profile's base model under the Printer tab

Fixed a bug that could cause variable transition lengths to not be used with Side Transitioning

Fixed a bug that could incorrectly result in Piece Too Short errors

The Eco-Friendly Update

Printing Features

- Print using Layer Batching

Multiple layers with each filament are printed before transitioning and moving back down

This technique is known in various slicers as Sequential Printing or Object-by-Object Printing

Simply slice a file this way in your slicer and load it into Chroma

Depending on your nozzle's vertical clearance, you can reduce the number of transitions in a print by 75% or more!

- Variable transition lengths by color

Requires Advanced Settings to be enabled

Set a Min and Max Transition Length in your printer profile

When selecting drive colors, a new slider allows the color's pigment strength to be selected

The transition length that is used will be interpolated based on the two colors' strengths

- Increased the maximum transition length to 230 mm

- Improved transition tower logic drastically reduces the number of Transition Inconsistency errors

- Improved handling of start sequence purges and layer changes

- Removed the "Layer Too Thin" limitation, allowing tower layers to be arbitrarily thin

- More settings for transition tower generation

Print Speed

Infill-Perimeter Overlap
