If you do multi color prints and in your project you have plate 1 with a multi-color print and a purge tower another plate also has a multi color print with a purge tower there is a bug in the slicers where, if you print any plate with a purge tower except plate 1 the print head will crash into the side of the printer.
This is on GitHub and they are working on it.
So for the time being if you print multi-color print ONLY PRINT PLATE 1.
UPDATE!!!
I have in my “Printer” Settings under “Extruder” tab the setting “Wipe While Retracting” UNCHECKED.
This seems to make a difference. When it is checked, which is the default, I do not see this issue.
So, for most people this probably isn’t an issue they would run into.
