Background: When changing tools,
gcode_Tascertains the position, in coordinate-space, of the new nozzle. The offsets are specified in physical space, so when leveling is active some additional adjustments are needed to get the position in the adjusted coordinate space.Meanwhile, when tools share the same carriage, tool change works like
G92in coordinate space w/r/t the carriage. So the software endstops need to be adjusted in XY to provide proper movement limits for the active tool. This adjustment must be made in linear space, with no leveling adjustment, in all cases where tools share the same carriage.This PR makes the following changes:
Note that Z software endstops are not changed because only the configured offsets apply, and the only tool with a Z adjustment (switching extruder #3994) manages that earlier, and transparently.
