Many prints failed on my Mosaic Palette 2S as the Filament Buffer inside is to small, if I print over 63mm/s in average between two sclices. Sometimes a splice happens directly after an pong which would drain the buffer completely.

Using the Parameter "Enable Print Speed Control During Splices:" inside the Pallete 2 OctoPrint plugin might help if you are willing to slow down the speed.

I've been quite happy with my Palette 2 on smaller, detailed prints with a lot of color changes. Bigger Prints with small as this one sized on 250% failed for me many times during this issue.

There are other options to prevent this issue as adding an external filament buffer, but I was not willing to print this huge thing which did not fit on my Printer/Palette configuration.

This ting is an external runout detector with a small filament buffer of 2mm just enough to slow down my printer using the M412 - Filament Runout command. I modified my Firmware to reduce the speed to 5% when the filament runs out.

#define FILAMENT_RUNOUT_SCRIPT "M220 S5\nM412 R"

The option "Enable Print Speed Control During Splices:" inside the Pallete 2 OctoPrint plugin will increase the speed-up to 100% after the splice is finished.

"Enable Print Speed Control During Splices:"

Normal Feed Rate: 100%

Splicing Feed Rate: 100% <- feel free to reduce it to your demand.
