Using the E3D Toolchanger.
I keep seeing unwanted retraction for every tool change. The gcode for the retraction is generated by S3D and NOT by the TFree, Tpre or Tpost gcode.
These retractions cause a blob of material every time the newly selected tool extrudes.
Anybody know where in S3D this is set or is this yet another automatic, unwanted thing that the slicer does which makes S3D a BAD choice???
Here's a sample of the gcode, note the E-5000 and E5000 retractions:
