I just upgraded from Monoprice Select 3d (not what you want) to an Ender 3 S1 and am super happy. I’d recommend the S1 over V2 for you if you think you might want to ever print flexible filament
I got mine for $299 USD on Amazon
You’ll want an enclosure if you want to contain smell or if you want to print in ABS (of any size, as drafts will fracture the print before it cools)
My experience has consistently been that Cura gave superior prints
Might need to set up a VPN server so you can access (if your Pi is behind a firewall) - this is what I do so I can access when away from home.
I’ve had best results with Cura, trees, support interface on using “grid” with “0.8mm interface thickness” and “75% interface density”, and when printing with 0.2 layer thickness and 0.1 gap between support and model (which then snaps to the 0.2 layer thickness)
Slicer plugins are available in Octoprint
Bad bot
I have 5 family members using Synology Photos (on a 4-bay Synology NAS) and it’s a great solution for us.
I don’t see myself going back to a cloud-based solution - this one is easy for me and secure.
I’ve got SHR running on my storage, and daily offsite backup to another family member’s house (protects against house fire etc for loss of 20yr+ of photos and videos).
Once you offload from your phone, you can pare down the photos remaining on the phone to whatever you want to be left.
