But for Zonstar Z9 or other XY core 3d printer
With Volcano setup

I find this cooler the best. Because aloud for front maintenance of hotend. With no need of removing him every time.

Compare to my previous setup. This is much more practical and got better air spread around the nozzle

to install 5015 fan
I do not use screws. only tie rips

Still not know where to install hotbed level sensor.
Because I use it only once. After Firmware update
Catch Z Offset is automatic at menu. Then its stored at printer memory

I do not use glue or tape. And almost never adjust bed knobs
One setting is good for many many days
That's how awesome my Zonstar Z9 is
