yeah, that's what i found when i had the ender 3, though didn't have a nice kit with a burner and had to use an arduino from my cnc.
Yeah, mine came with the magnetic bed.
So..... Does your printer have the magnetic bed? I just replaced my original print surface with a fresh one and while I'm happy with that product (exact replacement for the original surface) I'm considering buying the magnetic bed replacement next time around.... I did however notice that the replacement bed (Linked to above) states that it's got a 70c bed temp ceiling.... does yours (or did the one on the ender 3 pro) come with a similar warning?
Default PETG is 70c, but ABS is 100c.
Speak of the devil , I just fininshed printing 3 belt tensioners for my ender 5. used PLA though, Just need some god damned m5x8 screws to mount em...
Also have the petsfang going.. I have to modify the base though.. doesnt quite fit.
Next up for me , bed support struts ( down the line I want to get a dual z mod going)
Im so far down this rabbit hole, i doubt ill be able to crawl out lol
And like you said, be prepared to spend the next few months printing mods, I havent really printed anything else but that fan cage so far.
edit: taking it to another level?
