Purge Line settings difference between MK4 and Mini  

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?

RE:

Yes, you can copy fragment of start gcode from MK4 printer profile and paste it instead of the current fragment in the Mini profile.

Mini has single line purge with a comment as you pasted.

Notice that Mini probably does not need that line:

M569 S0 E ; set spreadcycle mode for extruder

Also notice you pasted gcode and some newline chars were removed.

One more thing, at the start there is move to X0 Y-4 which may be outside of the print sheet, so you may need to tweak it to something like G1 X10 Y-4

Also remember to save it as new profile so that the original one will not be overwritten on next profile update.

Hmmm looking at the that MK4 gcode it just does short purge line, no swirls because there are no Y moves...
