Currently Redeem does not support tool head offsets.
We want M218 T<tool> X<xoffset> Y<yoffset> Z<zoffset> to set the offset and save it to the local.cfg file. We may want to create a new category for multiple extruders in the config file. Maybe "[Extruders]" ?
In addition, T<tool> by itself should perform an entire tool head changing sequence, e.g. drop off current tool head and pick up the selected one.
