Blobs on Prime Tower - initial load too big?

I'm running TZB's FW, but he swears he hasn't touched this code - just an FYI.

I've gotten my MMU set up working wonderfully with semi-flex/98a. Thinking I was King of the World, I loaded up PLA and was right back in crashyfail city.

On filament change, the old filament is removed, then the new one loads to Bondtechs. It goes forward, putting a large blob of the previous filament on the tower, retracts and reloads as normal.

 

If I further decrease "extra reload distance" I can make the Prime Tower as rarefied as I'd like - but this does nothing to prevent the blob which is ejected on the first load.

 

Is this something I can fix in the slicer settings? I feel the distance in the firmware (again, Robert has assured me this is perfect and doesn't need tweaking, though I am unconvinced) of the initial load should be set shorter, and use "extra reload distance" to get the filament to the nozzle after the initial load-and-check procedure.

 

Does that make sense? Any advice?
