created first material - aurarum nintendo purple PLA
created first machine - prusa i3 mk3/mk3s - didnt change default values
created first test session
	named first run
	material aurarum nintendo purple
	machine prusa i3 mk3/mk3s
	optimization strategy aesthetics

first layer track height
	0.12 - 0.22
	15-30mm/s (changed due to less than 10 clogging in my previous experience)
	60 heat bed temp
	215 extruder temp

Generate .GCODE file button fails. asks to enter a valid number in the 0.12 first layer track input field
at this stage I was using microsoft edge. opened chrome and Generate .GCODE file button works now.

copied file to card, running gcode
machine bed leveled twice which was abnormal compared to other gcode generated with prusaslicer
	probable cause is double g28 without addition of W
	line 2 and again at line 6
	https://forum.prusaprinters.org/forum/original-prusa-i3-mk2-s-others-archive/g28-w-g80-solved/

settings for test lost from edge, speed reverted to default 5-20. this wasnt noticed due to text field failure in edge bug

bed leveled again after print completed caused again by the use of g28 without addition of W. should look like G28 W;
printer LCD information output stuck in heating... loop.
the fifth line from the bottom in the gcode m190 s20 in the end footer

rebooted printer just in case.
re-doing test with lower extruder temp and a slight increase in speed
	0.12 - 0.26
	10-30mm/s
	60 heat bed temp
	205 extruder temp
significantly improved results. 0.17 at 23mm/s centred around good results chosen as best.

extrusion temperature vs printing speed test
	using values on the spool of PLA 190-220
	using suggested 30-70mm/s
	track height 0.15 (as shown in video)
	other settings left default
		commented out line 10 which is the second bed leveling
		edited end of test routine added suffix W to g28
		edited end footer bed temp to 0 instead of 20 and commented out g28

filament jammed during the pause from 190 to 195. my guess the temp was too low
	i have found in the past the temp guides on the rolls of filament are lower than what i find usable
attempting again with increased temps and speeds
	205-235 temperature range
	30-90 mm/s
	0.15 track height
test completed successfully. cannot visually discern a difference between any of tests
under closer inspection near a lamp top right looked a little better than the bottom left
30mm/s 205c chosen as best

retraction distance test using default values
prusa slicers default retraction settings are significantly lower 0.8mm at 35mm/s
filament continued to jam here at various temperatures.
