I swapped out the parts cooling fan on my SV06 for a 5015 (Works Awesome)
Next step was to swap out the 4010 hotend fan for a 5015 fan aswell. (Works Awesome aswell).
Here is what i found interesting. I found when i removed the 4010 fan an oily substance on the fan and fan mount. Apparently its a fluid filled fan bearing, Thats a bad choice of fan to use.
I would switch out this fan with either a sleeve bearing or preferably a ball bearing fan.
I’m slowing improving some of the small ( and i mean very small ) imperfections of this machine.
Next i want to rebuild my own Marlin Firmware to add flow rate % and some other minor stuff missing in the GUI.
Then prob move to installing Klipper at some point.
I have no complaints with this printer. The quality of my prints are outstanding. It was calibrated perfect out of the box. Its fast.
We will see how all the bearings hold out. So far so good.
Usually when this happens it means the fans are dirty.
You can clean them by using canned air. Do this with the printer off or you will damage the fans.
Yeah, did use canned air several time and it does help, wasn’t aware fans could be damaged so easily. The noise only last for 30 to 40 seconds then goes to normal.
Any reason not to take the fans off and clean with a soft toothbrush? Also, what’s the life expectancy of a Hotend nozzles?
Thanks,
Mike
Yes, you can take them off to clean, sometimes there is filament string in the blades & it’s the only way.
Nozzle life depend on how much you print & if you use abrasive filaments or not.
So with that said, average life could be 6-12 months. I’ve had my SV06 Plus since the 2nd set of per-orders 2/23 and am still running the original nozzle.
Great info! Most of my printing is PLA & PLA+, replaced first nozzle after 6 months and so far this nozzle (7 months) is still printing fine.
Think my biggest issue with SV06 is on start-up when it hits the top rail. Now I use a caliper to set Z, unless I change the Filament. Once again thanks for your help.
