G28 ; having changed go home
G1 X-60.0 Y98.0 F9000 ; edge of bed to wipe
G1 Z0.05 ; close to bed
M109 S185 ; raise extruder back to normal
G92 E0 ;reset extruder axis to zero
G1 X-10.0 E5 F200 ;wipe a blob
G1 E-1 F1200 ;retract
G1 Z9.2 F9000 ; which is where we started from
I have used this code several times - the only issue is that the nozzle can ooze hot filament during its travel back to where it started - judicious use of tweezers helps to pull this away if needs be.

Am I right in understanding that you put the nozzle on the bed after a filament change and do the ooze-free wipe again? Presumably this can only work if you're not changing filaments at a height where dropping Z back to zero causes the x-carriage to strike the object on the bed?
