i used the PLA

The zheight was way easier to adjust because there was more time to compare against old one. vs running multiple tests

thank you jeff jordan 🫡

20260615 -0.200 still ass but better
20260615 -0.00 ass 

20260615 -0.250 much better but still ass

20260615 -0.300 has some spotting but is ok (lets try a benchy)
20260615 -0.350 looks same as 300
20260615 -0.400 looks good (im supprised my old shitty method worked at all
20260615 -0.450 WOW HUGE CHANGE no bubbling
20260615 -0.425 cant tell


final verdict stick with -.425 good smooth stuff




ask:
why isnt it sticking
does the screws cause a issue if fucked with?
assumptions
	zhight is bad
	
learning
- its really crackly i assume its water
- i cleaned really good with water soap and iso
- using Jeff jordan z life adjustment method so much BETTER! than standard zhight adjust
