Purge Line settings difference between MK4 and Mini

Hello all:

I have a question

Strange women, laying in ponds, distributing swords, is hardly a basis for a system of governance!

RE: Purge Line settings difference between MK4 and Mini

Ok, somehow I lost everything I just typed... 😫 

I would like to know if i can modify the Mini purge line settings to resemble that of the MK4 and have the Mini do the same "swirl" purge that the MK4 does.  the MK4 starts purging filament as the print head moves towards the steel sheet and it makes for a very clean purge.  The Mini does the same type of purge that it always does, just a straight line once the print head reaches the plate.

I am unsure if it is only the difference in the printer custom Start G-code commands in PrusaSlicer or if there is a mechanical difference in the steppers between the MK4 and Mini that allows the MK4 to do the swirls when purging that the Mini would not be able to do.

I pasted the two different areas of the custom G-Code in the printer tab of PrusaSlicer for Start G-Code below to show the difference.

Do I have the right thing to copy paste?  just copy from MK4 start print custom Gcode and paste to the mini and that would work?
