Print pausing over part during 'tool change'

[Sam_I_Am 1]

Using an Ender 3 with a Mosaic Palette 2 with Cura. Everytime it does a 'tool change' the print seems to pause slightly and extrude some filament in the last place it was before the colour change. This is causing small bits of the wrong colour to be deposited in the model. Does anyone know what cura setting could help stop this? I've already checked that the temperatures are all the same across each extruder settings.

I got same problem with Geeetech A10T. Its stop above printing element and make tool change and unretract leave blob behind. 

On s3d forum I was read than if you put tool change retraction distance to 0 that can help. 

Not tested it yet, I will do it tomorrow morning.
